Hello,
I have an annotation file for fsaverage, which I would like to map it to a particular subject. What would be the best way to do so?
I tried a combination of calls to mris_ca_train and mris_ca_label, but the latter gave me an error.
First I ran
mris_ca_train lh lh.sphere.reg fsaverage/label/<file>.annot fsaverage /tmp/<output>.gcs (where <file> and <output> are some file names)
and that executed without any problems.
Then I ran
mris_ca_label <subject_id> lh lh.sphere.reg /tmp/<output>.gcs ./lh.<newfile>.annot (here <subject_id> is some subjects' name, and <output> and <newfile> are some names)
and I got the error: could not open translation file $FREESURFER_HOME/Simple_surface_labels2002.txt
Maybe there is a simpler way to perform this task? Or maybe an easy way to fix this error? Any help will be much appreciated.
Thank you,
Peter
