[Freesurfer] FreeSurfer development version masks

Hello,

I am trying to freeze the development freesurfer version for today and I am denied access to copy the following files:

/usr/local/freesurfer/dev.backup/average/mult-comp-cor/fsaverage/rh/cortex/mask.mgh /usr/local/freesurfer/dev.backup/average/mult-comp-cor/fsaverage/lh/cortex/mask.mgh /usr/local/freesurfer/dev.backup/subjects/fsaverage6 /usr/local/freesurfer/dev.backup/subjects/fsaverage/scripts/fix-surf7.log /usr/local/freesurfer/dev.backup/subjects/fsaverage3 /usr/local/freesurfer/dev.backup/subjects/fsaverage_sym/scripts/fix-surf7.log /usr/local/freesurfer/dev.backup/subjects/fsaverage4

Are they instrumental? Are they the same as stable6? How can I have access to these? (I am in the Martinos cluster)

Thank you,

Aura M.
