two hopefully relevant points:
- phenix.refine always produces an MTZ file that contains the copy of
all inputs plus all is needed to run refinement (free-r flags, for
example). So if you use that file for deposition you have all you need.
- Unless there are strongly advocated reasons to do otherwise in your
particular case, you better use in refinement and deposit the original
data and NOT the one touched by any of available these days magic sticks
(that "correct" for anisotropy, sharpen or else!).

Phenix supports complete input / outputs of mmcif/cif format. For
example, phenix.refine can read/write model and reflection data in cif
format. It's been this way for a long time now.
