External Email - Use Caution

Dear Experts,

Having installed Freesurfer on WSL2, I was able to get the basic FS segmentation to run without error (i.e., recon-all runs just fine).  However, when I tried to run_samseg (--lesion) on a pair of T1/co-registered FLAIR images, I received the following error messages

Is there anything in the trace (below) that provides a clue?  Particularly, I don't understand the "unknown data type ID: 10".  Freesurfer accepts NiFTI files

My command: run_samseg -o $SUBJECTS_DIR/T1T2-samseg-test -i o_ADNI_002_S_4654__MRI-m072.nii rT1_o_ADNI_002_S_4654__MRI-m072_FLAIR.nii --pallidum-separate --lesion
