Hello,
I am trying to make a study specific template based on the instructions at: https://surfer.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates
However, on running the first step: make_average_subject --out newtemplate --subjects subj1 subj2 subj3 ...
I get an error while running the recon-all is trying to run the aparc to aseg step:

recon-all -s newtemplate exited with ERRORS at Thu Dec 5 11:29:52 EST 2019
On inspecting the mri folder, it seems the norm.mgz file has not been created at all. Looking at the flowchart of steps for the recon-all command, norm.mgz is supposed to be created in the CA Normalize step, which requires the talairach.lta in the newtemplate/mri/transforms folder, which seems to be missing as well. The only transform created in the transform folder is talairach.xfm. The talairach.lta is created in the EM GCA registration step. Do I re-run the EM GCA registration, CA normalize, and then contonue from aparc to aseg? I am not sure if since I am creating my own template, the EM GCA step requires any modifications? Any help will be appreciated.
Thanks, Nandita
