compatibility with local and Compute Canada installations (qsub not found)

Hello,

I am trying to install pydpiper and run the test_MBM_and_MAGeT.py script on the downloadable test-data example, but can't get much to work:

1) I tried installing the Singularity container on my local workstation, and cloned the latest version of pydpiper into the container (just so that I could get the testing script. I didn't install pydpiper because it seems to be part of the Singularity container). I then changed sample.cfg queue-type to "local" and removed the "time-to-seppuku" line. The command I use is:

python3 pydpiper_testing/test_MBM_and_MAGeT.py test-data

Unfortunately the program does not seem to move, with the number of stages processed being stuck at zero. Changing the queue-type back to sge comes back with an error that originates from "qsub" not being recognized.

2) I tried installing the Singularity container onto Compute Canada, and ran it with sge as the queue type, but this also seems to fail because of the absence of qsub:

Singularity> python3 pydpiper_testing/test_MBM_and_MAGeT.py test-data

If I am understanding this correctly, I assume that pydpiper really isn't intended for running on a single workstation, but rather a computing cluster? If so, what are the key requirements for a cluster to be compatible with the use of pydpiper?

Thanks!
