Dear phenix list,

My 0.75 A refinement has some problems in its higher resolution bins, so I thought I might try adding in IAS scatterers. However, the phenix.refine (version 2008_09_13_0905) crashed when I set "ias = True". I hope someone here can help me figure out the problem. I include snippets of output below, as the entire error message was very lengthy. Am I misusing the command, is there a problem with my system setup, or what?

Regards,
Anna Gardberg
