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

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
