Thanks for the info Ziad and Anthony,

I found out what my issue was:
One of my subject's surfaces seems to have major issues when loading a 1D.dset. It seems only the lower part of each hemisphere is being mapped to the standard mesh surface (I'm including a tiff). So, when I tried displaying another subj's data on this surface it was severly distorted, as well as when I tried displaying this subj's data onto another subj's standard mesh surface.
This subject's surface reconstruction was done awhile ago, so perhaps I need to redo the reconstruction.

Also, some subjects' standard mesh flat surfaces are not displaying (their original flat surfaces display fine). Everything seems to load the same as when loading the original surfaces.
I had an issue a little while ago with flat surfaces not displaying and followed Ziad's solution to fix it:
SUMA_CenterOnPatch = YES
Is there anything special about the standard mesh space that would require additional environment variable to be set?


The colormap works great. Should have realized it was that simple.

I'll definitely try an average subj brain to project my data to in the end.
