Install pipesnake

Hi I am new to Nextflow. Does anyone have specific experience with pipesnake? During the set up, I encountered the following error.

nextflow run ausarg/pipesnake -profile test,singularity --outdir /path/to/output

ERROR ~ Error executing process > ‘AUSARG_PIPESNAKE:PIPESNAKE:IQTREE (batch of 4120 fasta files)’
Caused by:
Process AUSARG_PIPESNAKE:PIPESNAKE:IQTREE (batch of 4120 fasta files) terminated with an error exit status (2)

Is there a /path/to/output in your filesystem? exit status 2 is unrelated to Nextflow, but it could be this --outdir path.
