Please help! I've hit a roadblock and can't identify the cause of the problem. I run the following slurm script

!/bin/sh

SBATCH --ntasks=1

SBATCH --mem=5Gb

SBATCH --cpus-per-task=4

SBATCH --time=1:00:00

SBATCH --output=maker%j.out


module purge
module intel/2018.1.163
module openmpi/3.0.0
module maker/3.01.03


****gff3_merge -d ragtag.scaffolds.fasta_master_datastore_index.log**

But keep getting an error saying that it can't find the gff3_merge command.**
