Can TORTOISE use field mapping to correct distortions?

There is a way to make DRBUDDI (blip-up blip-down data) to initialize with fieldmap data but we do not directly support fieldmap correction.

Are the fieldmaps in units of Hz or mm?

Basically DRBUDDI is to generate a fieldmap. Its solutions are generally better than typical fieldmaps.

So if you really want to use a fieldmap, first it needs to be converted into a displacement field, and then provided to DRBUDDI as an initial solution so that DRBUDDI makes it better.

But if you dont have blip-up blip-down data, it doesnt really apply.
