External Email - Use Caution
Dear FS's experts,
I am trying to downsample some surface data from fsaverage to fsaverage6 with the following command:
mri_surf2surf --hemi lh --srcsubject fsaverage --sval ./lh.fsaverage.s8mm.mgh --trgsubject fsaverage6 --tval ./lh.fsaverage6.s8mm.mgh --cortex
However, the output surface data is a binary file contrary to the source one (please see attached).
Would anyone have an idea of the problem?
Best,
Matthieu
