Hello!
I have a volumetric mask of the cuneus and I would like to convert it to a
label and then convert that label to fsaverage space.
So far I did mri_vol2label --i cuneus.nii.gz --l cuneus.label
But how can I now convert cuneus.label to fsaverage?

Hi,
I'm trying to understand mri_surf2vol and mri_vol2surf but I'm not able to

Hello!
I performed two registrations: diffusion-to-orig.dat and

How can I get a transformation matrix that maps orig.mgz to rawavg.mgz? I

My first thought was to simply convert the aseg.mgz to native functional

Hi,
In a Freesurfer help webpage it says that to convert an image (eg

should use mri_vol2vol, but for a segmentation (aseg.mgz) we should use
mri_label2vol. I converted the aseg.mg
