Hey all you SUMA gurus,

I'm interested in averaging a couple datasets in SUMA space. From the documentation it looks like I need to map all my subjects to Icosahedron space, extract a functional dset for each subject (3dVol2Surf), then I can use 1deval to average the subjects.

First, I'm wondering if running MapIcosahedron space on each subject yields a common surface. Should I be able to load subject 1's dset onto subject 2's Icosahedron surface (without losing alignment)?
Or do I need to further align each subject's surface?
From the documentation, I'm assuming that the averaged dataset could be loaded onto any subject's Icosahedron surface (so I'd think individual datasets should be able to be loaded across subjects).

So far I have run MapIcosahedron on all my subjects and extracted dsets using 3dVol2Surf. When I load subject 1's dset in onto subject 1's Icosahedron surface, the result looks the same as if projecting from AFNI. However, when I try loading subject 1's dset onto subject 2's Icosahedron space, the alignment looks way off (not in the correct anatomical locations). Not sure if I'm doing something incorrect in 3dVol2Surf (although data looks fine when loading within subject data), or perhaps I'm missing a step.

On a seperate note I'm wondering if there is any way to convert a palette into a cmap file? I have a particular color map I want used in SUMA, however it is 16 colors, not continuous.

I'd prefer a cmap file, but I also tried getting a .col file:
Scale2Map -input file.1D.dset -cmapbd multi_rh.pal -cmap multiRH_n16 -anr 3.14 -nointerp > colormap.col

I keep receiving an error: Could not find colormap multiRH_n16.

My .pal file has this: ***PALETTES multiRH [16]
The scale is from 1 to -1

Any suggestions?
