Hi Wei, this is a bug in the error msg. It is trying to say that your source subject is not in the $SUBJECTS_DIR. doug

Dear freesurfers,

I am trying retinotopy analysis in freesurfer. For "fieldsign-sess", I encounter the following problem when I type "fieldsign-sess -a rtopy.self.lh -occip -s SUBJ01" or "fieldsign-sess -a rtopy.self.lh -occip -sf sessid":

*/media/users/zhouw4/testf/retinotopy/SUBJ01/log/fieldsign-sess.log* *subject: Undefined variable.*

my structure of retinotopy fold is : retinotopy | |--sessid |--SUBJ01 |--subjectname

     |--bold
         |--001
             |--f.nii
             |--rtopy.par|

I really appreciate it if you could give me some idea about that problem. Thanks a lot in advance.
