Thanks for your input, John. I see, so from what you say, anything installed via pip in the virtual environment then exists in the module/class include namespace within galaxy python command line tool code. Good to know.

I'll note that this approach is compatible with toolshed tools (I'm testing it via one) because it relies on a galaxy admin managed .loc file to list the generic and customized reporting modules. The (toolshed) reporting tool ships with a .loc file that doesn't reference any customized reports, e.g. blast_reporting_templates.loc.sample is

#value name description # Add list of html templates here templates.html_report Standard Report Provides report with sections and table sections

And then a galaxy admin adds an entry: # Customized templates listed below templates_custom.html_report Customized report Test customized report

Task for getting a customized report in place does require manual steps though: customized module, addition of the .pth file, and editing of the above .loc file.

Cool to know, that is very nice. However, I meant that these steps requiring external modules outside the context of job execution will require the Galaxy admin to setup these dependencies - they are not installed with the tool shed installs. It sounds like this is not a large problem though. Glad this working for you. -John

If this is working it sounds reasonable. I think my approach might be to setup Galaxy inside a virtualenv (as recommended here https://wiki.galaxyproject.org/Admin/Config/Performance/ProductionServer) and just install your extra dependencies inside that virtualenv using pip.

$ . <path_to_virtualenv>/bin/activate $ pip install dependency1 $ pip install dependency2 ...

After that you should be able to just do a normal Python import.

I think you have another open question about the next steps of this - but just to make it explicit - everything is going to work better in "the Galaxy ecosystem" if you can avoid calling code from tools like this and just use the sort of stock options. For instance - neither of these approaches will work with the tool shed. Sometimes that is not possible - I understand that - but I just thought I would put the disclaimer out there.
