External Email - Use Caution Dear Freesurfer experts,
A quick question. I am trying to convert my cortical thickness analysis results into a gifti file preferably combining left and right, like so: mris_convert --combinesurfs lh.gamma.mgh rh.gamma.mgh both.gamma.gii I get this error: error: ERROR: MRISread: file 'lh.gamma.mgh' has 0 vertices! Probably trying to use a scalar data file as a surface! It then try to convert a single hemi: mris_convert lh.gamma.mgh test.gii but I get the same error. The gamma file looks fine to me, so I am not sure what the issue is. I am running this version of freesurfer: freesurfer-darwin-macOS-7.2.0-20210713-aa8f76b Could someone provide an example how this is done? Thank you so much! Lauri Tuominen
