Cannot unlock directory

[gevro]

Hi, Snakemake will not let me unlock the directory.
I am running snakemake --unlock, but I'm still getting this when I run the drop pipeline:

check for missing R packages
Structuring dependencies...
Dependencies file generated.

Unlocking working directory.

Error: Directory cannot be locked. Please make sure that no other Snakemake process is trying to create the same files in the following directory:
/gpfs/scratch/evrong01/droptest/.drop/modules/aberrant-expression-pipeline
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.

Is there any way to run DROP without snakemake?
Snakemake causes many problems and bugs, and is generally not a good system.

Update: If I run drop update it fixes the problem. It is still a bug though. snakemake --unlock should work.

Execute snakemake unlock, without the --.
DROP is fully based on snakemake.
