Hi Tom,

you could try mris_convert with the -c option. E.g.:

mris_convert -c ~/data/study1/subject1/surf/rh.sulc.nii.gz ~/data/study1/subject1/surf/rh.white ~/blah.gii

The command requires an existing surface file that matches the per-vertex data as the 2nd argument (for reasons I don't know). You should be able to use the fsaverage surface files that come with FreeSurfer for your use case ($FREESURFER_HOME/subjects/fsaverage/lh.white and rh.white).

If one does not have a surface file, one could do the conversion in Python using nibabel or in R using freesurferformats (an example conversion script for R is at [1]).

Best,

Tim

Hello,

I have a question regarding the conversion of functional fsaverage lh and rh files (created from the Yeo lab MNI to fsaverage projection software: https://secure-web.cisco.com/1nRJbdVDTJHwxxGMU9q1fmvcPt_Df0AIfr6uIaGGD96UkPw...) to a *gifti file*.

For example, 'rh.sub-13_ses-fmri1_task-awak_run-1_space-MNI152NLin2009cAsym_desc-preproc_bold_cleaned.allSub_RF_ANTs_MNI152_orig_to_fsaverage.nii.gz'

This is necessary because my end goal is to then transform that gifti file, using wb_command, to the fs_LR HCP surface.

Any help would be greatly appreciated,
