Hello,
I am familiar with afni's volume-based tools, but I have no shifted toward using surface-based tools from freesurfer and CONN toolbox. In order to upload an visual cortex atlas consisting of 50 ROIs I first converted it to a .nii file. I'd now like to determine the coordinates of each ROI center of mass. For a volume-based data set I would use something like 3dClust. However, SurfClust does not allow .nii files.
Is there a way to obtain surface ROI information from .nii files? Or to convert a .nii file to the spec and surface files required for SurfClust?
