Python framework for working with atomic configurations, potentials, and algorithms.

I have been experimenting with ssneb in tsase, and have observed that the example fails to complete, with the following error 'RuntimeError: No pseudopotential for Se'. Although I had set the VASP_PP_PATH variable to my local copy of pseudopotentials (i.e. uspp-736), I note that while no error is raised wrt Cu pseudopotential, the vasp-ext.py cannot find the Se pseudopotential. My question therefore is: do I need a VASP license to be able to use the Vasp calculator in ssneb ? Otherwise, can one use the PAW potentials generated for another code, say PWSCF to run ssneb jobs in tsase ?
