Hi Garth,

they need to be in the same SUBJECTS_DIR, although it can just be a symlink.

Hi Doug & Freesurfer experts,

Is there a way to run mri_label2label to copy a label from one subject to another in a different SUBJECTS_DIR, or do the subjects have to be in the same directory for label2label to work (e.g. vs_subject1 in SUBJECTS_DIR_A to subject1_anat in SUBJECTS_DIR_B)? I am having trouble with specifying the source and target registration/white matter files. The subjects in both directories are the same, the only difference being which version of freesurfer the recons were run with and a slight difference in the naming convention.

I tried just copying the file, but when I tried to visualize the label, it looked incorrect. Below are the outputs I got when running mri_label2label. When I do not use the --srcsurfreg & --trgsurfreg flags, I get very similar errors, but with shorter path names that it cannot find.

Thanks for your help!
