Re: [HCP-Users] volume to average surface with Nearest Neighbour interpolation

The fs_LR 32k spheres use a resolution (vertex spacing) that is suitable for 2mm fMRI data, but it sounds like you are using structural-resolution voxels. As Matt says, I would put the fs_LR surface into your volume space, and do only a single mapping, because nearest neighbor or enclosing voxel

Re: [HCP-Users] volume to average surface with Nearest Neighbour interpolation

I think I would probably resample the subject’s own FS_LR registered surfaces into the FreeSurfer space (an exact transformation) and then do a single mapping from volume to surface. You would need to figure out the affine matrix that describes this transform. Peace, Matt. From:
