Consuming Theory

[alecandido]

We considered the problem of producing a theory for the tutorial, that is what we are always doing.

Something that people might be even more interested in (at least some other people, if not everyone) is how to consume a theory.

It is simply done during a fit, just specifying the ID, but if you want to reuse FkTables and/or grids for making your own plots or inspecting them, we are providing no instructions.

Plus, the main interface for accessing full theories is validphys, but maybe we want to be a little bit more NNPDF agnostic (if theory content can be useful also for someone else).
In particular, it is not trivial also for myself to just say: I want to plot the FkTable X from theory N with PDFset Y (in particular, it would be useful also for my neutrino/thesis plots, but I'm gonna steal them from reports).

I added some notes to consuming-drafts/stuffs.md, but I will try to recast part of them as a Tutorial for the website + further content.

At the moment, the only example I have to extract content of a theory from the validphyssphere I wrote myself, following @RoyStegeman indications:
https://github.com/NNPDF/mcpdf/blob/cb43028ce8f62329cd055e21608e0a6b7bce5b3c/src/mcpdf/nnpdf/theory.py

In case I want to write something able to interact with the theory format (once you download it yourself from the server, I won't do any networking, if you can't do by hand use vp-get), where should I put?

1. in pineko
2. in pineline
3. somewhere else (propose...)
