[Freesurfer] fsfast preproc question

The volume produced from the -mni305 option in preproc-sess, does not look like a brain (it seems to be mostly cerebellum. I have attached an image). Is this the expected behavior? I have included the relevant path and information below:

source /cluster/neuromind/dwakeman/wmh/software/nmr-stable53-env #<note this just points to the Martinos stable53 env> setenv SUBJECTS_DIR /cluster/neuromind/dwakeman/wmh/analysis_1

preproc-sess -surface fsaverage5 lhrh -s $SUBJECT -fwhm 6 -fsd e_o -mni305 -per-run -stc odd

Any of the subjects in that subjects directory have the same effect. including nmr00809 (if you want a specific example).

The only guess I have is that maybe fsaverage5 is somehow interacting with the mni305 option?

Thanks, D
