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.
