PS. Tom pointed out that the anomalous measurability in Xtriage depends on the sigmas, which is obviously a problem for synthetic data - you can generate fake sigmas with "add_sigmas=True", but the resulting statistics will be meaningless.

I guess it depends on what you're looking for as the final output.  It's easy to generate an MTZ file with anomalous Fcalc (this is in the GUI too, of course):

phenix.fmodel model.pdb high_resolution=2.0 type=real wavelength=0.9792

Extracting some kind of useful summary from the data might require a little extra scripting - although this may be the kind of thing we should just add to Xtriage (which only reports "anomalous measurability" right now).
