Now that I'm able to view caret rendered volumes in SUMA (thanks Ziad), I find that I still can't do what I set out to do: mapping functional data from afni onto these. What I need to be able to do, if I understand correctly, is somehow assemble a spec file along the lines of what is created with either of the SUMA_make_spec scripts. Since these don't appear to work with caret data, I think I may have to create it from scratch. (Though maybe it's possible to adapt the surefit script to caret data, since caret is supposed to be using surefit for its segmentation anyhow.) For the sake of completeness, let me see if I can give you some background:
This is the method I'm currently using to visualize the data. Apparently I'm not passing a .param file to it properly this way, hence the error.

Error SUMA_Load_Surface_Object_eng: Volume Parent specified without .param file.
Parent Volume Alignment will not be done.
It subsequently won't link to afni. I am not by any means opposed to hand-crafting a spec file, but when I tried to peanut butter something workable together by looking at a sample SUMA spec, I didn't have any luck. Sorry to trouble you so often, but I'm very close to being able to do what I want to do with these, which would bring great joy to many.
Thanks for your help so far, and I hope that you can help me with this part.
