Singularity & Nirvana

[yr542]

I was wondering if I could know what Singularity path to use with Nirvana?

I know that in order to pull the package I need to do the following:

singularity pull docker://annotation/nirvana:3.14

but what path would I use in a singularity exec command to run Nirvana. Given what I see from looking into the singularity file the path will be /opt/nirvana/:

singularity exec nirvana_3.14.sif /bin/bash -c "cd /opt/nirvana/ && ls"

however, I would like to confirm this?
