External Email - Use Caution        

Hello FS experts,

I downloaded some anatomical data. I have defaced full images and
pre-skullstripped images for each participant. I tried the defaced images
first, but FS skullstripping looks a little off (possibly because the
defacing hides bits of the cranium in some images and causes problems in
mri_watershed). So I would like to use the pre-skullstripped files as my
initial inputs.

I have placed the pre-skullstripped file for each participant in
$SUBJECTS_DIR/$subjid/mri/orig/. Each participant's skullstripped input
volume is named 001.mgz.

I then submit the following command in a script to my slurm queue (after
setting appropriate FS env vars), where the script input ${1} is the
$subjid mentioned above:

recon-all \
    -subject ${1} \
    -all \
    -openmp 40 \
    -noskullstrip

The output log from FS ends with the following error. The
function mri_em_register seems to be looking for brainmask.mgz, and fails
to open it. If the input image is already extracted from the skull, do I
need to manually call it brainmask.mgz rather than 001.mgz? Or am I missing
something else in my function call (like order of flags)? Does
-noskullstrip need to come before -openmp, for example?

Thanks!
Jim H.
