[Chimera-users] Will ChimeraX deal with data in Fourier space (MTZ format)?

Yes it would be nice for ChimeraX to be able to do the Fourier transform and other steps to convert an MTZ structure factors file to a density map. Others have requested this but no one has ever pointed me to documentation on how missing data and NCS symmetry are handled in this conversion. I’ve looked online but never found good enough info to make it easy for me. If you have detailed info on this I’ll look at it.
We are working with Paul Adams at LBNL to make ChimeraX and Phenix talk to each other, but our focus will likely be on cryoEM more than x-ray.
