2. Modify the main_job.sh script with your desired commands and SLURM directives. For example:

   #SBATCH --output=%x.%j.out # %x.%j expands to slurm JobName.JobID
   #SBATCH --error=%x.%j.err
   #SBATCH --partition=general
   #SBATCH --qos=standard
   #SBATCH --nodes=1
   #SBATCH --ntasks-per-node=1
   #SBATCH --time=01:00  # D-HH:MM:SS
   #SBATCH --mem-per-cpu=4000M
