I run into an error when I try to do the tutorial on ROI group analysis. I downloaded the tutorial set, but did not put it into FREESURFER_HOME/subjects, because my computer doesn't allow it. I made my own folder and copied everything in there. The error arises when I try to map a label from the fsaverage subject to a target subject:

 mri_label2label \

>   --srcsubject fsaverage \

>   --srclabel fsaverage/label/lh.BA45.label \

>   --trgsubject 004 \

>   --trglabel 004/label/lh.BA45.label \

>   --hemi lh \

>   --regmethod surface

srclabel = fsaverage/label/lh.BA45.label

srcsubject = fsaverage

trgsubject = 004

trglabel = 004/label/lh.BA45.label

regmethod = surface

srchemi = lh

trghemi = lh

trgsurface = white

srcsurfreg = sphere.reg

trgsurfreg = sphere.reg

usehash = 1

In related posts I read that it might have to do with the creation of symbolic links. I made sure that in my SUBJECTS_DIR, fsaverage is a symbolic link to my FREESURFER_HOME/subjects directory, in which surf/lh.sphere.reg etc are stored. What am I doing wrong? Does it still have to do with the fact that I put the tutorial data in another folder?

Hope you can help me,

Thanks in advance,
