Designed especially for neurobiologists, FluoRender is an interactive tool for multi-channel fluorescence microscopy data visualization and analysis.
Deep brain stimulation
BrainStimulator is a set of networks that are used in SCIRun to perform simulations of brain stimulation such as transcranial direct current stimulation (tDCS) and magnetic transcranial stimulation (TMS).
Developing software tools for science has always been a central vision of the SCI Institute.

Release Notes

FluoRender 2.15.2

These issues were fixed:
1. It failed to read a TIFF file with multiple strips when saved with LZW compression.
2. Memory leaks when multiple GPUs were installed and an OpenCL kernel was used.
3. A volume data set could not be compressed with OpenGL RG texture compression.
4. The application icon looked jagged under Windows.
5. Rulers were not saved in a project file.
6. Applying paint brush strokes on a data set larger than 4 GB caused FluoRender to crash. After fixing, it performs best on the latest graphics cards with 12 GB of memory (Geforce GTX Titan X or Quadro K6000).

These improvements are included:
1. When the keyboard shortcuts for the paint brush tool are used, it allows single mouse clicking to select/unselect a circular region.
2. Speed of applying a paint brush stroke is significantly improved, especially for large data on slow computers.

These new features are included:
1. A probe tool to create a two-point ruler along the viewing direction. When used in combination with the paint brush tool (via key board shortcut), it creates a cylindrical selection along the ruler.
2. A profile tool to calculate intensity profiles along rulers. This tool is best used along with the probe tool to generate an averaged intensity profile within the cylindrical mask region.
