No, unfortunately not. If all you want is the template, you can run mris_make_template to get the tif files. I think that's pretty fast.

Re: [Freesurfer] Making a custom experimental template
Doug,
 
This is awesome--thank you!
 
I have one final follow-up question, and maybe a bit of a long-shot: given that this process is a little time intensive, is make_average_subject able to "add in" extra subject to the existing template? E.g. If I've collected 10 subjects currently, but will shortly collect another 10--is the intermediate alignment information from the first 10 subjects saved anywhere that can be usefully used for the average subject of the final 20?
 
Thanks again!
 
Joakim

Hi Joakim,

here are some instructions on what to do (some of which you've already
done):

doug

# Create an average subject (Creates $SUBJECTS_DIR/newtemplate)
make_average_subject --out newtemplate --subjects subj1 subj2 subj3 ...

# Register each subject to the new template (do for both lh and rh)
# Creates lh.sphere.reg.newtemplate and rh.sphere.reg.newtemplate
foreach subject (subj1 subj2 subj3 ...)
cd $SUBJECTS_DIR/subject
mris_register -curv surf/lh.sphere \
$SUBJECTS_DIR/newtemplate/lh.reg.template.tif \
surf/lh.sphere.reg.newtemplate
end

# Get thickness values in the newtemplate space for GLM analysis
mris_preproc --surfreg sphere.reg.newtemplate --s subj1 --s subj2 --s
subj3 ...

# Create another average template based on the previous one:
# (Creates $SUBJECTS_DIR/newnewtemplate)
make_average_subject --out newnewtemplate --surf-reg
sphere.reg.newtemplate \
--subjects subj1 subj2 subj3 ...
