Dear Freesurfer users,
I've been trying to map a Qdec contrast sig.mgh to the native volume of a subject using mri_surf2surf (to get from Qdec fsaverage surface to native surface) and mri_surf2vol (to map from native surface to native volume cortical ribbon). However, the last step goes wrong: I get a nii with the same range of values as were in the surface, but the nonzero voxels are scattered all over, so I guess there is something wrong with the surface-to-voxel coordinate mapping. Below is my code, any ideas on what goes wrong?
Best regards,
Rene
mri_surf2surf --hemi rh --srcsubject fsaverage --noreshape --sval sig.mgh --trgsubject subj01 --tval sig_2subj01.mgh
mri_surf2vol --surfval sig_2subj01.mgh --hemi rh --fillribbon --identity sub01 --template subj01/mri/orig.mgz --o sig_2subj01_volumetric.nii
