WebJan 18, 2024 · This can be decreased by increasing the number of cores in the Bowtie2 command. For example, one could specify eight cores for Bowtie2 with -p 8 and adjust the request in the SLURM script to #SBATCH -n 10 (that is, eight cores for Bowtie2 and one each for SAMtools view and sort). The memory usage of Bowtie2 depends primarily on …
