Cannot run ants.registration in HPC (slurm)

Describe the bug When I submit running command of the bash file to the HPC, the process got stuck at ants.registration step. It seems that the forward transformation and other output of registration cannot be saved. I created a tmp folder (default for ANTsPy) to save these outputs, but it still did not work. Does anyone have ideas about this issue? Thanks in advance.

Ans use sbatch sbatch --cpus-per-task=8 unittest.sh to run, but it is always in the Pending Status instead of Running, do you have any idea about this?

This is exactly the time to ask your HPC support, this is unrelated to ANTs

This sounds to me like resource restrictions on the jobs as being submitted to SLURM (low CPU count and RAM). I suggest contacting your HPC support for help with requesting appropriate resources.
