External Email - Use Caution        

Hello to all, I am new to FreeSurfer. By executing recon-all I get the permission error.
Is there a way to change the $SUBJECTS_DIR, such as /share/users/my user/subject name ?

$ recon-all -subject 102109 -i T1w.nii.gz -all

mkdir: cannot create directory `/share/Application/FreeSurfer/Install/freesurfer/subjects/102109': Permission denied
mkdir: cannot create directory `/share/Application/FreeSurfer/Install/freesurfer/subjects/102109': Permission denied

cp: cannot create regular file `/share/Application/FreeSurfer/Install/freesurfer/subjects/102109/scripts/build-stamp.txt': No such file or directory
cat: /share/Application/FreeSurfer/Install/freesurfer/subjects/102109/scripts/build-stamp.txt: No such file or directory
/share/Application/FreeSurfer/Install/freesurfer/subjects/102109/scripts/patchdir.txt: No such file or directory.

Thanks for the help!
