Dear AFNI experts,
I'm new to AFNI/SUMA and I have trouble figuring out how to make use of the D99 surface template. I have macaque fMRI data registered to the D99 space, and now I'd like to map the 3D volumes to a surface template for visualization. The D99 space data downloaded from your official site includes a 3D atlas, a 3D template, and a folder of 365 ROIs surface files (.gii and .dset). From my understanding after reading the instructions, I need to create a surface model via e.g. FreeSurfer, then make the spec files for SUMA use. I could not find the D99 space brain tissue segmentations on your site, so should I do this step myself? If so, what should I do if the mesh I make differs from where the D99 ROIs are defined? If this is a noob question, could you direct me to the relevant information?
I'd really appreciate your help!
