CAVER is a software tool for analysis and visualization of tunnels and channels in protein structures. Tunnels are void pathways leading from a cavity buried in a protein core to the surrounding solvent. Unlike tunnels, channels lead through the protein structure and their both endings are opened to the surrounding solvent. Studying of these pathways is highly important for drug design and molecular enzymology. 

=== Job CAVER (single node) ===

Example script ''slurm-caver-script.sh'' to run CAVER on 1 node of the ''cpu'' partition using 1 core and at most 16 GB of memory:

<code bash slurm-caver-script.sh>
#!/bin/bash

#SBATCH --time=1-00:00:00
#SBATCH --ntasks-per-node=1
#SBATCH --mem=16GB
#SBATCH --partition=cpu
#SBATCH --qos=cpu
#SBATCH --job-name=run_caver
#SBATCH --output=%x.o%j
#SBATCH --error=%x.e%j

echo "JOB NAME    : $SLURM_JOB_NAME"
echo "PARTITION   : $SLURM_JOB_PARTITION"
echo "MEMORY      : $SLURM_MEM_PER_NODE MB"
echo "HOSTNAME    : $HOSTNAME"

module load caver
