9/9/2009
FluoRender 1.2.0


New features:
1. Scale bar for size reference. The length, unit and text of the scale bar can be set by the user. The length of scale bar is linked to viewport zoom. Though scale bar is available for perspective projection, it's recommended that use it in orthographic mode for accuracy.
2. Clipping planes. Clipping planes can be set for different channels independently, or they can be linked for all the channels.

Issues fixed:
1. Zoom of render view is calculated according to the relative size of the dataset bounding box to the viewport, rather than previously the projected voxel size to screen pixel size. Thus even datasets acquired with different objectives and scanning resolutions can generate comparable rendered results, with zoom being set to similar values.

User Interface of FluoRender (v2.10.0):


fluorender ui

Instructions for Basic Operations:


I. Click "Open Volume" icon in the toolbar (A). In the file choosing dialog select the volume dataset (multiple files can be selected at the same time). The selected datasets are loaded in the "Datasets" panel (B). The file choosing dialog contains additional options for loading 3D and 4D sequence. You can load several file formats, including TIFF, OIB, OIF, LSM, and NRRD. The chosen volume data are added automatically into the "Render View" (F) and "Workspace" (C).

II. Click "Open Mesh" icon in the toolbar (A) to choose one or multiple polygon mesh file(s). Only Wavefront's OBJ format is currently supported. If you export OBJ files with textures from a modeling tool, please use TGA as the texture format. Transparency of the OBJ data can be set either within FluoRender or through a texture with alpha channel.

III. When OIB, OIF, or LSM files are loaded, FluoRender will try to acquire meta data from these raw formats and set voxel size and channel colors accordingly. If no meta data are available, colors are assigned automatically as red, green, blue, then white, according to the order that datasets are added to the viewport. Colors can also be set with the color chooser in the "Properties" panel (H), or simply double-click on the RGB color values and type in the desired RGB values, or else R, G, B, W, or P, which are shortcuts for the preset colors.

IV. Viewport interactions are controlled by the mouse; a three-button mouse is ideal. To rotate the view, click and drag with left mouse button; to move the view, click and drag with the middle mouse button, or hold down the ctrl key and drag with the left mouse button; to zoom the view, click and drag with right mouse button.

V. Rendering properties of the volume dataset are displayed in the "Properties" panel, and each channel has its own settings. To switch between the channels, click the channel name in the "Workspace" panel (C). Settings for rendering properties are discussed in detail below.

VI. To switch render mode, click on the radio buttons above the "Render View" (F).

VII. To save the rendering results as an image, click "Capture", and enter an image file name.

VIII. Loaded datasets and their settings can be saved as a FluoRender project file. To save a project file, click the "Save Project" icon in the toolbar (A) and enter a project file name.

IX. To open a project file, click the "Open Project" icon in the toolbar (A), and choose the file. The saved project is loaded with all the datasets and their settings.

Note:
    The Project file remembers loaded datasets by their paths, and when the paths to the datasets change, FluoRender will try to search the datasets within the project file folder. So when you copy projects, copy datasets and project files together in order to open them correctly later.

User Interface Elements in Detail

A. Toolbar

fluorender toolbar
  1. Open Volume. Choose volume datasets to open. Supported formats: TIFF, OIB, OIF, LSM, NRRD. Manufacturers' raw formats usually contain meta data, which help to determine the data type. However, to load datasets without meta data, you probably need to set the additional settings in order to load 3D and 4D sequence correctly.
  2. Open Project. Open a saved project file. Starting from version 2.8, project files are associated with FluoRender executables. Double-clicking the project files will launch FluoRender automatically.
  3. Save Project. Save all current settings to a project file.
  4. New View. Open a new render view.
  5. Show/Hide UI. Show or hide the UI panels. The individual panels can be show or hide from the drop-down list.

B. Datasets Panel
fluorender datasets

All loaded datasets are listed in the Datasets panel. Double-click on a dataset, or select it and hit "Enter" to add it to the latest opened render view. Right-click an item to show its contextual menu. You can choose a render view to add the selected dataset, or you can delete, rename and save (for volume datasets only) the selected dataset.

Datasets panel has its own toolbar.
  1. Add selected dataset to the render view.
  2. Rename selected dataset.
  3. Save selected dataset.
  4. Bake selected volume dataset. It saves the volume with its property settings (gamma, thresholds, etc.) applied.
  5. Delete selected dataset.
  6. Delete all datasets.

C. Workspace

fluorender workspace
 

Workspace lists and organizes all active datasets that have been loaded to the render view. Right-click the name of a render view to show the contextual menu. You can toggle the visibility of the view, collapse or expand part of the tree, or add a new group. Right-click the name of a dataset to show the contextual menu. You can toggle its visibility, remove a dataset from the render view, or remove the dataset from the view. Double-click a render view, group, or dataset to toggle its visibility.

To create a group, choose "Add Group" from the contextual menu, or drag any data channel to the lower empty space of the scene view window. Output adjustments (gamma and brightness) can be set for each group individually in the layered and composite modes. To set these parameters, choose the group or a data channel within the group, and use the Output Adjustments panel (E). In layered and composite modes, the settings only affect the chosen group, while in depth-sorted mode, the settings will affect all channels.


The order and hierarchy of the groups and channels can be changed by dragging and dropping the selected group or channel on the tree. The order of the channels will affect their rendering order in layered mode: channels that are higher in the window will cover those that are lower.

The currently selected volume data is ready for volume paint selection and editing. You can use different types of brushes to highlight voxels of the selected volume data, and you can also extract or remove the highlighted parts from the volume data.

Workspace has its own toolbar.
  1. Hide/show current selection.
  2. Add a volume data group.
  3. Add a mesh data group.
  4. Delete current selection. Id the current selection is a dataset, it is removed from the view port, and becomes "inactive". You can load it again from the Datasets panel.
  5. Switch to painting mode and use a brush to highlight voxels of the selected volume dataset. You can also hold down the Shift key on keyboard as the shortcut.
  6. Set painting mode to diffusion. Diffusion currently highlighted voxels of the selected volume dataset. You can also hold down the Z key on keyboard as the shortcut.
  7. Set painting mode to reset. Paint on highlighted voxels and remove them from selection. You can also hold down the X key on keyboard as the shortcut.
  8. Reset all highlighted voxels from selection.
  9. Erase highlighted voxels from the selected volume data. A new volume data will be created with "_DELETED" in its name. If you apply erase operation again on a volume with "_DELETED" in its name, no new volume will be generated.
  10. Extract highlighted voxels from the selected volume data. A new volume data will be created and added to the render view in a new group. You can also save the result from the Datasets panel.

fluorender outputOutput adjustments allow you to adjust gamma, brightness and equalization for each RGB channel of the final output images, after the volume data are rendered. This is usually for fine-tuning the output images.

  1. Red channel link. Check this box if you want the adjustment of the red channel of the output image link to other channels.
  2. Red channel gamma, brightness and equalization adjustment slider.
  3. Red channel reset.
  4. Red channel gamma, brightness and equalization input values.
  5. Green channel link. Check this box if you want the adjustment of the red channel of the output image link to other channels.
  6. Green channel gamma, brightness and equalization adjustment slider.
  7. Green channel reset.
  8. Green channel gamma, brightness and equalization input values.
  9. Blue channel link. Check this box if you want the adjustment of the red channel of the output image link to other channels.
  10. Blue channel gamma, brightness and equalization adjustment slider.
  11. Blue channel reset.
  12. Blue channel gamma, brightness and equalization input values.
  13. Save as Default. Save all the settings as default. Data loaded next time is set to this default settings.


Note 1: In layered and composite modes, since channels are rendered independently, we can group channels into groups and set the output adjustment settings for each group independently. In depth-sorted mode, the settings affect all channels irrespective of how they are grouped. Refer to the instructions on Scene View to see how groups are created and organized.

Note 2: The gamma, brightness and equalization settings can be set independently for the R, G, and B channels, or channels can be linked by checking the checkboxes. Under certain conditions, some R, G, and B channels are linked automatically. For instance, when the R and G channels of one dataset have nonzero values, they will be linked; this auto-linking allows hues to be kept constant when changing the output adjustments.

Note 3: Equalization can be used to equalize uneven brightness for both 3D and 4D renderings. Equalization also enhances details at the same time.


F. The Render View Panel and Its Controls


fluorender renderview

The render view panel displays the rendered dataset; render view properties are set by the controls arranged around the border of the panel.

  1. Render Modes. Render modes control how multi-channel volume datasets are rendered. The three modes are: Layered mode: similar to Photoshop. Channels are layered on top of one another, with the rendering order specified by their order in the "Scene View" panel (C). Depth mode: channels are rendered according to their depth values; this mode is spatially faithful to the data. Composite mode: channels are rendered individually and then blended together for the final rendering. For groups, the render modes can be overriden by the depth mode. Turn on "Group: Depth" in the properties panel of any dataset within the group to set the group into depth mode. See H. Rendering Properties for details.
  2. Capture. Click to take a screen shot of current rendering and save as a tiff file.
  3. Persp/Ortho/Free Flight. Choose perspective, orthographic views, or free flight mode.
  4. Background Color. Sets the viewport background color.
  5. Center. Toggles display of the viewport camera's center of interest.
  6. FPS. Toggles display of rendering rate (in frames per second).
  7. Depth Int. The checkbox toggles depth attenuation. The slider sets the intensity of the effect.
  8. Zoom. Moves the viewport camera towards or away from the center of interest (changing the overall size). This is equivalent to dragging with the right mouse button held down, but with more accuracy. The "1:1" button sets the zoom to reflect the 1:1 voxel to pixel ratio. Click this button and it uses one screen pixel to render exactly one voxel of the volume dataset.
  9. Reset XYZ rotation angles to zero.
  10. XYZ Rot. Sets the orientation of the viewport camera. XYZ rotation values can be set by numerical entry, by slider, or by dragging with the left mouse button held down.
  11. Save as Default. Save all the render view settings as default. The next time opened views are going to use the default settings.
  12. Clipping frame. The yellow rectangle shows the area of the viewport to be captured when exporting a movie.
  13. Camera center. The camera center widgets shows the position of the center of camera and its rotations.
  14. Scale bar. This indicates the physical scale of the dataset, but will only be accurate in orthographic (not perspective) view. The length of the scale bar can be set in the Rendering Properties panel (H).
  15. FPS. Display the rendering speed if FPS is enabled.


G. Clipping Plane Settings

fluorender clippingThese settings determine the orientation and position of front and back clipping planes, which delimit the part of the volume to be displayed.

  1. Sync all chan. Check this box to synchronize the clipping planes of all the channels of the open dataset. If unchecked, each channel can have independent clipping planes.
  2. X1, Y1, and Z1 clipping plane control sliders. Use these sliders to control the positions of the front clipping planes.
  3. X1, Y1, and Z1 clipping plane position inputs. Control the positions of the front clipping planes by numerical entry.
  4. X, Y, Z clipping plane link. Use the check boxes to link the movement of the front and back clipping planes.
  5. X2, Y2, and Z2 clipping plane position inputs. Control the positions of the back clipping planes by numerical entry.
  6. X2, Y2, and Z2 clipping plane control sliders. Use these sliders to control the position of the back clipping planes.
  7. Align to View. Click this button to align the six clipping planes to the view, so that Z1 is facing to the view, Z2 is facing off the view, X1 is on the left hand, X2 is on the right hand, Y1 is on the top, and Y2 is on the bottom.
  8. Reset to 0. Click this button to set the clipping planes rotation back to zero in the object space.
  9. Clipping plane rotation angle inputs. These numbers are the relative rotation angles of the clipping planes to the object. Set these numbers to rotate the clipping planes independent of the object.
  10. Clipping plane rotation angle sliders. These sliders control the rotation of the clipping planes relative to the object.


Clipping Plane Usage in Detail

When the mouse cursor moves over the clipping plane settings panel, the clipping planes of the current selected channel will be displayed in the render view (A). Only the clipping plane being modified will be displayed when moving the sliders (B). The 6 clipping planes act like a box to clip the dataset (C). If the two clipping planes of one axis are linked, one will move with the other, keeping a constant separation, and both clipping planes will be displayed in the render view (D).

H. Rendering Properties


fluorender properties


Volume properties are displayed in the "Tools" window, when the name of the dataset is selected in the "Scene View" window. The "Tools" window is dockable, so that the user can rearrange its position by dragging its title bar. Most values can be controlled either by slider or by numerical entry.
Note: Starting from FluoRender 2.9, render view updates instantaneously without the need to hit Enter key for the above numeric inputs. Earlier versions still require user to hit Enter key after input.

  1. Gamma. Controls the shape of the nonlinear transfer curve. Setting a value greater than 1 accentuates signals of low intensities, while a value less than 1 suppresses signals of low intensities. A low value is usually desirable for confocal datasets, where noise is often present as low intensity signals.
  2. Extract Boundary. Controls how much boundary-like structures are extracted.
  3. Saturation point. Sets an intensity threshold above which all values are mapped to the highest output intensity. Moving the slider to the left results a steep transfer curve with more pixels saturated.
  4. Threshold. Sets an intensity threshold below which voxels are not displayed in the output with the first slider and sets an intensity threshold above which voxels are not displayed in the output with the second slider. This setting is independent of gamma value setting. In MIP mode, this setting is disabled.
  5. Luminance. Controls overall brightness of the final rendering by changing the highest output intensity.
  6. Shadow/Light. Check the check box to enable shadow effects. Use the first slider to adjust shadow intensity. Use the second slider to adjust highlight intensity. Shadow effects can be directional. Set the shadow direction in the Settings dialog (see below).
  7. Alpha. Controls the transparency of the voxels. In MIP mode, this setting is disabled.
  8. Sample Rate. Controls the quality of the output rendering (higher rate = better quality, slower rendering).
  9. Shading. Controls the output intensity of the shaded area of protruding structures.
  10. Colormap. Assigns a colormap instead of a single color to the selected data. The colormap has a gradual change from blue to green to red depending on the scalar values of the data. User can control the blue point (for low scalar value) and red point (for high scalar value) with the sliders and input boxes. When enabled, a legend of the colormap currently used will also be displayed in the rendering view.
  11. Color. Color used to display this dataset. Double-click to select the entire text window. Shortcuts for commonly used colors: R/r - red, G/g - green, B/b - blue, P/p - purple, W/w - white. Color is overriden when colormap is enabled.
  12. XYZ Spacing. Sets the voxel size, using the unit of length (e.g. microns) from the scale bar settings. Sizes are linked between channels, so that settings for one channel affect all channels in the same viewport. If the metadata of the TIFF file contains the voxel size of the data, these values are filled automatically by the program.
  13. Scale bar settings. The checkbox toggles the display of the scale bar on/off. The input box and drop down list set the length of the scale bar and the length unit. The "Show Text" checkbox toggles the text label for the scale bar on/off.
    • NOTE: Though the scale bar can be displayed in both perspective and orthographic views, its length is correct only in orthographic view. In perspective view, its length is imprecise due to foreshortening.
  14. MIP. Turn on MIP mode for the data. In MIP mode (without colormap), alpha and high threshold are disabled and low threshold becomes the threshold for shading only. Use the shading in MIP and adjust the shading to render the surface details properly. In color-mapped MIP mode, gamma, saturation point, luminance, alpha, extract boundary, and high threshold are all disabled. Use the Output Adjustment (E) to fine-tune the brightness and contrast. The MIP mode only works in Layered and Composite render modes. Switching to Depth mode automatically turns MIP mode off, and a warning dialog box is shown when the user attempts to enable MIP in Depth mode.
  15. Smoothing. Apply filers in real-time and remove the artificial patterns. The results are usually slightly dimmer than without the filtering due to its noise suppression effect, but the renderings should be smoother, especially in the low signal intensity regions.
  16. Synchronize Group. Enable this option synchronizes the settings of all the data within current group.
  17. Depth Mode in Group. Enable this option to set the group of the current dataset into depth mode, irrespective of the current render mode of the render view. The datasets within the current group are rendered with the correct depth occulusions, and the group are combined with other datasets according to the current render mode, which should be layered mode or composite mode.
  18. Reset. Resets all settings as the saved default.
  19. Save as default. Saves the parameter settings as the default, which are applied to volume datasets loaded later.


Open volume options

There are several options in the Open Volume dialog. Mask volumes, 3D and 4D sequence files are loaded by selecting these options.

fluorender openvolume

  1. When a volume dataset is saved as a series of 2D images, check this option and FluoRender will try to load the sequence as a volume. Please note that you probably need to edit the names of the image sequence, since FluoRender will try to find the last occurrence of consecutive digits and use them as the index for the sequence.
  2. This is the identifier for a time sequence. Similar to the above option for 3D sequence, FluoRender uses consecutive digits after the identifier as the index for a time sequence.

Note to previous version FluoRender users: Previous versions of FluoRender always use "_T" as the identifier, if you want to open 4D sequences created previously, please make sure this option is set correctly.

Edit

Click the Edit button from the Toolbar (A), and open the Edit dialog. Use the settings to control brush behavior for volume paint selection. There are two ways to edit volume datasets: 1 use the volume paint selection; and 2 use volume calculations. All volume datasets loaded into Workspace and shown in the render view are ready for volume editing.

To use volume paint selection, select the volume dataset from the Workspace, and then start with the first brush in the toolbar. You can also hold down the Shift key. Adjust the brush size with either mouse wheel or the options in the volume edit dialog. Then paint in the view port to highlight voxels you want to select. You can use the diffusion brush to diffuse the highlighted voxels into regions that are connected to the existing highlights. Or you can use the reset brush to remove the highlights. When you think you are done with painting, you can either erase the highlights with the eraser in the toolbar, or extract the highlights out with the extract tool in the toolbar.
The following figure illustrates the usage of the three brushes:

fluorender paint

You can select two volume datasets and calculate using four volume calculations:
Subtract. Subtract Volume B from Volume A.
Add. Add Volume A and B together.
Divide. Divide Volume B from Volume A.
And. Find the common parts of Volume A and B.

fluorender edit

  1. Falloff controls how low intensity voxels are selected. Setting a lower number will select more low intensity voxels. However, when you use the diffusion brush, more voxels are considered "connected".
  2. The influence of the output adjustments. You can use Gamma, Luminance, and Equalization to influence the volume painting results. This is the factor controls the strength of their influence.
  3. It controls the size of the inner circle of the brush.
  4. It controls the size of the outer circle of the brush.
  5. It controls how many iterations are used for calculating the growth. With more iterations, growth is stronger.
  6. Display this help page.
  7. Save the painting selection parameters as default.
  8. Select a volume dataset from the Workspace and click "Load", the selected dataset will be ready for calculations as operand A.
  9. Select a volume dataset from the Workspace and click "Load", the selected dataset will be ready for calculations as operand B.
  10. When Volume A and B are both ready, click any one of the four calculations to get the result. The resulting volume will be add to the Render view within a new group.


Settings

Click the Settings button from the Toolbar (A), and open the FluoRender Settings dialog. Use the settings to control the global behavior of FluoRender upon all the datasets.

fluorender settings

  1. Auto Save Project. Enable this option so that every time FluoRender captures a rendering or exports a movie, it is going to save the current settings as a project file, in the folder where the files are exported. You can go back and open the project later.
  2. Variable Sample Rate. Enable this option to automatically lower the sample rate for volume data when using mouse interactions.
  3. Micro Blending. In depth mode (including the depth mode within a group), enable Micro Blending and FluoRender is going to blend the colors from different channels at voxel level, which usually can generate more accurate colors. This is especially useful for RGB images, since e.g. green and red colocalized at the same place will result in yellow. And the blending is not restricted to three channels in RGB, any number of channels can be blended.
    • Note: This feature is going to slow down the rendering speed in depth mode. Depending on the system, the factor of performance drop may vary.
  4. Mesh Transparency Quality. This options sets the layers of transparent mesh objects to render. It only works when mesh files are opened and added to the render view. The more layers set, the more accurate of the rendering results, but it also slows down the rendering speed quite significantly as the number of layers increases.
  5. Shadow Direction. Check the check box to enable directional shadows. Use the slider to control the light source position.
  6. Set default colors for confocal channels with different excitation wavelengths. This only works for confocal raw formats that wavelength info can be acquired from meta data.
    • Note: The settings in this dialog are applied to FluoRender instantly when you change the settings. The settings will remain in effect until FluoRender exits, even the settings are not saved. FluoRender is going to use the saved settings upon next start.



Plugins


ImageJ Macros & Plugins - 3D Confocal File Conversion
ImageJ Macro - 4D Confocal File Conversion & File Format Specs

ImageJ Macros & Plugins for 3D Confocal File Conversion

The most commonly-used input data format for FluoRender is 8-bit multi-layer TIFF files; manufacturer-specific formats (Zeiss, Leica, Olympus, Nikon) can be converted to multi-layer TIFF using a custom ImageJ macro. There is a guide for basic ImageJ operations available: ImageJ_guide.pdf.

Downloading ImageJ:

  1. Download ImageJ from ImageJ website:
    http://rsbweb.nih.gov/ij/download.html
  2. Launch ImageJ.
  3. From the Edit menu select "Edit->Options->Memory & Thread", then increase the memory allocation. For 32-bit systems, use 1450MB; if a greater value is set, ImageJ fails to start. For 64-bit systems, higher settings are possible--set the value just below the total system memory.
Downloading the macro files:

  1. To use the macro, install the "loci_tool" plugin for ImageJ first.
    Download: plugins.zip 5MB
  2. Unzip the downloaded zip file and copy the files into the folder ImageJ/plugins/. Then restart ImageJ.
  3. Download the format conversion macro:
Notes on the macro files:

  • [Fluorender_RGBmarge.txt]
    This macro converts the original confocal data file (Zeiss, Leica, Olympus, or Nikon) to an RGB multi-layer tiff file. The output files are placed in a "RGB_tif" folder, with "_1ch, _2ch, _3ch" appended to the filenames.
  • [Save_8bit_multiCH.txt]
    This macro extracts channels from the original confocal data file (Zeiss, Leica, Olympus, or Nikon) and generates an 8-bit multi-layer tiff from each channel. The output files are placed in a "TIFF_Files" folder, with "_B, _R, _G, _W" appended to the filenames.
  • [Save_8bit_multiCH1024px.txt]
    This macro is similar to the macro above, except that before saving as multilayer TIFF, it resamples the data from 1024x1024 px to 512x512 px. Use this resampling when graphics memory is insufficient. Attention: This macro fails to interpret the confocal data correctly if multiple samples are stored in a single file. Instead, store each sample as a separate file.(The resulting 8-bit multi-layer file is usually mentioned as a volume dataset.)
How to run the ImageJ macro:

  1. Open the macro file with ImageJ (drag-and-drop is the easiest method), then from menu select "Macros->Run Macro".
  2. In the dialog box, select the folder where the input confocal data are. The macro reads all files in the folder, so keep only confocal data files there.
Attention: Spaces " ", hyphens "-", and wide characters (such as Asian characters) in the file path or file name cause the macro to read data files incorrectly. Use underscores "_" instead.

About the loci tools plugin

  • We use the loci tools plugin (website http://www.loci.wisc.edu/ome/formats.html) to read various formats of confocal files into ImageJ. As of April 2010, the latest version has become incompatible with the Save_8bit_multiCH macro, so use the older version of the plugin provided above (plugins.zip).



ImageJ Macro for 4D Confocal File Conversion and File Format Specifications

4D confocal files in OIB, OIF and LSM formats can usually be loaded correctly without any conversions. Other formats need to be converted to TIFF and follow certain naming conventions.

For easy converting and naming the manufacturer-specific confocal files, an ImageJ macro is provided for download. It can be downloaded here: 4DmultiCH_FluoRender.txt.zip
To use the macro, install the "loci_tool" plugin for ImageJ first: plugins.zip (5MB)
There is also a guide for basic ImageJ operations available for downloading: ImageJ_guide.pdf.

How to run the ImageJ macro:

  1. Open the macro file with ImageJ (drag-and-drop is the easiest method), then from menu select "Macros->Run Macro".
  2. In the dialog box, select the folder where the input confocal data are. The macro reads all files in the folder, so keep only confocal data files in the folder.

After the files are converted, make sure they are saved in the same folder and named properly. Just open one time point from the whole sequence. If the dataset has multiple channels, load all the channels from one time point. Choose "4D Seq." from the "Make Movie" panel (D in the manual), and the whole time sequence should be recognized. Use the time slider to browse through the data, and use "Save..." to export the whole sequence.

Attention:
1. Spaces " " and hyphen "-" in the full file path or file name cause the macro to read data files incorrectly. Use underscores "_" instead.
2. In order to convert the 4D file format, ImageJ will read all the dataset into system memory. So ImageJ 64bit version and system memory more than 6 GB are recomended.

4D file naming conventions:
In order to render 4d movies correctly, certain naming and formating conventions need to be followed, which is described below. If you have any problems of 4D rendering, please first check if the file names follow these convetions.

For multiple channel 4D data, each channel of each time point is saved in a separated file. The file name should contain a pattern as "_T###", and "###" denotes the number of current time point, which should increase continuously and has the same number of digits for all time points. Different channels of the same time point can be distinguished by any additional words, but the same channel of different time points should be identified by the same word.

For example, a 4D dataset contains 120 time points and 3 channels, and we can name each individual file like:
For time point 1,
dataset_name_T001_R.tif
dataset_name_T001_G.tif
dataset_name_T001_B.tif
For time point 2,
dataset_name_T002_R.tif
dataset_name_T002_G.tif
dataset_name_T002_B.tif
...
For time point 120,
dataset_name_T120_R.tif
dataset_name_T120_G.tif
dataset_name_T120_B.tif

In the above example, "dataset_name" can be any thing that identifies all the files within the same 4D dataset, and it should be the same for all files. "_T###" is used to identify the time point number and should be the same for all the channels of the time point. The number to identify the time point is increased by 1 for each time point and all the numbers have 3 digits with zero padding. "_R", "_G", and "_B" are used to identify channels and they should keep the same for different time points.

FAQ

1. I cannot start the software


Case1;

Q: I downloaded FluoRender and double-clicked the FluoRender icon to run the program, but it popped an error dialog window, saying "The program can't start because teem.dll is missing from your computer. Try reinstalling the program to fix the problem.". What's the problem and how can I fix it?

A: Probably you didn't extract (or unzip) the entire folder from the downloaded zip file, so you were running FluoRender without the necessary library files. Under Windows, some commonly used zip/unzip programs include WinZip and WinRAR. If you are not using any zip/unzip programs, you have to copy the entire FluoRender folder inside the downloaded zip folder to a certain directory of your hard drive, such as the C:\ root directory or your desktop.

Case2;

Q: When I run FluoRender I get the error message "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." Any ideas?

A: It's very possible that you run FluoRender on a newly installed system and the Microsoft Visual C++ 2005 Redistributable Package has not been installed. We currently compile and build FluoRender with Microsoft Visual C++ 2005 and FluoRender needs the Redistributable Package in order to run. Most systems already have this package installed, but if you get the error message you can try to download the package form Microsoft. If you are using 32 bit Windows (x86), you should download the 32 bit version of the Redistributable Package, and if you are using 64 bit Windows (x64), you should download the 64 bit version of the Redistributable Package.

Case3;

Q: When I start FluoRender, I barely see the user interface and it disappears immediately, or it won't start at all. What is the problem?

A: FluoRender uses certain graphics hardware features to render the volume data. Currently only a limited number of graphics harware is compatible with FluoRender. We recommend a recent discrete graphics card from nVIDIA. (GTX400 series)

2. I can't use FluoRender to generate any images

Q1: I can run FluoRender and see the user interface, but after I load volume data into the program, it doesn't display anything. Why?
Q2: I can run FluoRender and see the user interface, but after I load volume data into the program, it stops responding and crashes. Why?


A: If you have these problems just occasionally, please refer to the Memory problem. FluoRender uses certain graphics hardware features to render the volume data. Currently only a limited number of graphics harware is compatible with FluoRender. We recommend a recent discrete graphics card from nVIDIA. (GTX400 series)

3. FluoRender crashes when loading files/project

A: Currently FluoRender loads all the data you open into both main system memory and graphics memory, and there is a limit the total memory FluoRender can use. If FluoRender crashes, 1) you can try to load less channels or resample the data (preferably with ImageJ). 2) please use 64 bit version of FluoRender (64 bit Windows system required).

4. Does FluoRender have a MacOSX/Linux/UNIX version?

A: Currently we are only developing FluoRender on Windows platform, and we recommend running FluoRender on a Windows based PC desktop. Intel based MacBook Pro can run FluoRender by installing a Windows system on Bootcamp.
