Save overlap matrices to files

[andreyl]

Dear EPW community,

can somebody please tell me a way to save Amn and Mmn matrices to disk and reuse them on new run, if such exists.
It takes significant amount of time, when, for example I need to change some wannerisation parameters leaving the rest of the calculation the same.

Dear Andrey,

I would suggest you use wannier90 to test different wannierization parameters, and when you are happy you run the epw calculation

Thank you, Carla, indeed an option

Actually, I overlooked the existence of pw2wannier.
So, just for a note, if one starts from finished scf and nscf calculations, an QE example for pw2wannier "Examples/PP/WAN90_example"
provides a routine to obtain overlap matrices (*.amn and *.mmn files). From this point one can start W90 calculations and play with the parameters.

Yes, sorry, I meant that but I didn't specify it properly - using pw2wannier and wannier90 one can do that easily
