sbatch: error: Email notification address error: No TLD found in domain

[htwangtw]

When no email address was provided to fmriprep-slurm, the generated bash script will have the mail-user option like this:

#SBATCH --mail-user=None

I did not encounter issue when running jobs on Beluga, but is having issue with narval.
A potential solution is, when no email address was supplied, remove the relevant options.

I can self assign and work on this.
