Displaying overlapping statistics
Dear developers, dear community,

I have a mesh of a subcortical brain structure and would like to add the results of two group comparisons as overlays (t-stats, FSL). The areas of these statistics partly overlap. My goal is to show which areas are uniquely affected for [group A vs. controls], which areas are uniquely affected in [group B vs. controls], and which areas overlap in the two. I successfully added the maps to the surface and set the threshold to 0.95 and 1. The statistics are displayed in a shaded way, including the colour bar. Is there any way to get rid of this shading, so that the significant area is only displayed in a single shade of colour?

What I've tried so far is thresholding and binarizing the t-map in FSL, but this procedure did not seem to be compatible with Surfice (as it resulted in a single shade of colour, but the affected area seemed odd, i.e. way too large).

Any help is greatly appreciated.
Thanks for this very useful visualization tool!
Josephine
