External Email - Use Caution        

Hi Ruopeng,

 

I have the colormap I’m interested in using.  It’s a 256 colormap with RGB values.  I could save it as a binary colormap if I know the precise format or an ascii formatted colormap.

 

Thanks,

Dave

There isn’t a way to do that at the moment. So you want to use a continuous spectrum with 256 color stops as the color map?

Hi,

 

I’d like to load in a custom color map to be used in color percentile-scaled functional images into FreeView (version 3.0; Build Aug 11, 2020).  I can’t seem to find a reference for defining and loading a custom color map.  I have done this for custom lookup tables and that’s all fine but now I’d like to define a ~256 RGB colors and use that in place of the standard color maps (e.g. Jet, NIH, PET, etc.). 

 

Thanks,

Dave
