Reproducing pseudodata replicas in n3fit
Created by: Zaharid
I would like to reproduce both the training validation split and the actual pseudodata used to fit a given n3fit replica. I am not sure that is possible at the moment but I believe it must be. Specifically, it should be possible to look at the LHAPDF header (https://github.com/NNPDF/nnpdf/blob/5a8ee6a76cb6e6980ae299e19c2359b5ff0043f8/validphys2/src/validphys/fitdata.py#L330) together with the fit runcard and recover all the information for seeds and so on.
Looking at the code (i.e. https://github.com/NNPDF/nnpdf/blob/d35489bde7bfa5c64abd024a45320d4d442f3733/n3fit/src/n3fit/io/reader.py), it seems that that should be possible, but it should be
- Documented
- Easily doable in vp
I'm happy to do the second part, but would be grateful for guidance of what goes where (that ends up in the documentation).
