Data processing when no darks/flats are associated with the data

[yousefmoazzam]

It's possible that in the future we would have to deal with data that has no darks/flats at all. Currenty, httomo doesn't support this option, so this feature would need to be added. This raises the question of how this situation would be presented inside httomo.

One option would be to have the darks and flats params for the loader have type Optional[DarksFlatsFileConfig], and then use None values for both when there are no darks/flats associated with the data.

@yousefmoazzam I think this is done now?

Perhaps the issue title should be more specific; I believe the issue was intended for the situation of processing data that has no darks/flats and we want to skip any kind of normalisation. Ie, there's no darks/flats at all (no darks/flats in the dataset which contains the projections, and no external darks/flats either).

With that in mind, I'm not sure if this issue is done, I've personally never tried to run httomo on data that has no darks/flats at all and skipping normalisation entirely, have you?

ah right, yes the issue tittle slightly confused me. I reckon we can have something like Data processing without flat/darks provided? That is a valid case indeed that might need attention later.

Haha yeah that's fair enough, feel free to reword the title if it helps 🙂
