Hi list,

I have carefully assessed the guidelines by surf2surf --help, but I need for your help.

I want transform the z.nii.gz, which I obtained from seed-based functional connectivity by FS-FAST, from the fsaverage to fsaverage5.

I have run:

mri_surf2surf --s fsavarege --hemi lh --sval-tal-xyz ../fc.Xseed.surf.lh/g1v0/intercept/z.nii.gz --trgsubject fsaverage5 --tval lh.zfsaverage5.nii.gz --tval-xyz

./fc.Xseed.surf.lh/g1v0/intercept/z.nii.gz is the FS-FAST output in fsaverage

lh.zfsaverage5.nii.gz would be the FS-FAST output in fsaverage5

but this error occurs
/Applications/freesurfer/subjects/subject_prova/fsavarege/surf/lh.sphere.regNo such file or directory
