> I agree that more information to referees is desirable, & I've often wanted to see the coordinates and the structure factors to check things. But to follow up after publication, there are still a lot of structures deposited without structure factors - why is deposition of structure factors not compulsory? And who can change things so that This is probably an idiot newbie question, but the vast majority of structures I've seen in the PDB w\ "structure factors" only have amplitudes. Granted, you could calculate phases from the model; but shouldn't a structure factor be a complex number instead of a real number? I'd think there should be the experimental phases, or at least model phases with the weighting scheme the authors used for their final maps for it to be called a structure factor...but evidentally I'm wrong.
