Update to the latest version of biobakery_workflows

Dear biobakery_workflows development team,

I have met one problem — UnboundLocalError: local variable ‘qmax’ referenced before assignment.

So, I want to update my current version of biobakery_workflows. But how to update?
biobakery_workflows 16s --version
wmgx.py v0.1

biobakery_workflows wmgx --version
16s.py v0.1

Could you give me some suggestion?

Thank you very much.
