Hi all, I'm trying to improve Python handling of FreeSurfer-generated .nii surface files (https://github.com/nipy/nibabel/pull/315).
If I'm reading load_nifti.m (https://code.google.com/p/fieldtrip/source/browse/trunk/external/freesurfer/load_nifti.m) and load_nifti_hdr.m correctly, there are three possible shapes, given a surface with x nodes: x < 2^15 => (x, 1, 1) x = 163842 => (27307, 1, 6) otherwise => (-1, 1, 1) (and glmin = x) On the other hand, https://surfer.nmr.mgh.harvard.edu/fswiki/mri_surf2surf#line-37 suggests that there might be other reshaping cases. For example, this suggests that ico6 should result in a shape of (6827, 1, 6), however I have found that mri_surf2surf[0] produces a volume with (-1, 1, 1). So I want to verify that the above are all of the possible shapes, or get more information to account for any undiscovered possibilities.
