Hi all, I'm trying to use -cifti-resample and I'm having a hard time understanding what the arguments are. After specifying the input and template cifti files, there are options for left-spheres, right-spheres, and cerebellum-spheres. How do I use these options? The help text says to provide "a sphere with the same mesh as the current left/right surface" and "a sphere with the new left/right mesh that is in register with the current sphere" - what does this mean, and how are these spheres related to the surfaces in the input and template files? Do these options override the surface information in the template? What is cerebellum-spheres, since I thought that subcortical areas are stored as volumes rather than surfaces?
My end goal is to downsample the input surface to ~10k nodes/hemisphere (for input to a very computationally-intensive model), so following the advice from this previous thread http://www.mail-archive.com/[email protected]/msg00039.html I used freesurfer to decimate the left and right hemisphere 32k spheres. FYI this required manually editing the GIFTI files to have version "1.0" instead of "1", otherwise freesurfer chokes on reading them. Now I'm trying to figure out the next step - should I be creating a new CIFTI template using these decimated spheres, or can I use the left/right spheres options? Thanks!
