Hi Lizanne,

A possible solution would be to create a symbolic link to change your fsaverage 
symbolic links when you source a different Freesurfer version:


Source 7.2.0
Go into $SUBJECTS_DIR
rm fsaverage
ln -s $FREESURFER/subjects/fsaverage


Best,
Avnish

Subject: [Freesurfer] ERROR: Label BA1_exvivo does not exist in SUBJECTS_DIR 
fsaverage


        External Email - Use Caution

Dear freesurfer Experts,



I’ve been trying to run the fMRIPrep container on multiple subjects using two 
different versions of fmriprep (fmriprep-22.0.2.sif and fmriprep-22.1.0.sif) on 
a Linux computer. Most of the time, the container runs without errors, however 
occasionally, it exits with the error message: “ERROR: Label BA1_exvivo does 
not exist in SUBJECTS_DIR fsaverage! The fsaverage link probably points to an 
older freesurfer version”



I have checked the mailing list where this error has been mentioned but haven’t 
found the solution yet.



Here’s some additional information that might be helpful:

-          The …/fmriprep/sourcedata/freesurfer/sub-096/label directory, the 
rh.BA1_exvivo.label file is present (and has viewing permissions), but the 
lh.BA1.label file is missing (not sure if this needs to be included).

  *   The recon-all log file has been attached



I would appreciate any insight or guidance on what may be causing this error 
and hot to resolve it.



Best,



Lizanne
