I am new to freesurfer so I apologize if this is a simple answer.

i'm running mris_ca_label to get the BN atlas parcellation:

mris_ca_label -1
/users/bkavanau/data/bkavanau/temp/derivatives/fmriprep/sourcedata/freesurfer/sub-004/label/lh.cortex.label 001 lh
/users/bkavanau/data/bkavanau/temp/derivatives/fmriprep/sourcedata/freesurfer/sub-004/surf/lh.sphere.reg
/users/bkavanau/data/bkavanau/temp/derivatives/fmriprep/sourcedata/freesurfer/lh.BN_Atlas.gcs
/users/bkavanau/data/bkavanau/temp/derivatives/fmriprep/sourcedata/freesurfer/sub-004/label/lh.BN_Atlas.annot

But it seems freesurfer is having an issue reading my lh.cortex.label file: 

/users/bkavanau/data/bkavanau/temp/derivatives/fmriprep/sourcedata/freesurfer/sub-004/label/lh.cortex.label: ascii: bad interpreter: No such file or directory

Might anyone have thoughts on how to resolve? I've seen adjacent errors before, but none related to ascii specifically.

thank you!
