Directory cannot be locked if previous snakemake run failed

[clody23]

I often get this error when the first run fails and have to rerun the analysis. This occurs when I run MToolBox as:

MToolBox-variant-calling -rpk -j 5 --cluster-config cluster.yaml --latency-wait 60 --cluster 'sbatch -p cluster7 -n {cluster.threads} -t {cluster.time} -o {cluster.stdout}'

This is the error:
Error: Directory cannot be locked. Please make sure that no other Snakemake process is trying to create the same files in the following directory:

If you are sure that no other instances of snakemake are running on this directory, the remaining lock was likely caused by a kill signal or a power loss. It can be removed with the --unlock argument.

The way I usually solve this is to do:

MToolBox-variant-calling -rpk -j 5 --unlock

and then rerun the command line above
