Hallo, This must be a naive question, but following Dr. Zwart's previous post and as I found in the web (http://www.phenix-online.org/phenix_wiki/mmtbx.twin_map_utils) this should be a utility to calculate a detwinned map. I just installed phenix and everything seemed to be fine during installation. But, where is this utility ? I cannot find it.

It spits out the maps afterwards. Unfortunately, refniement against twinned data is not yet fully implemented in phenix.refine but we are working on that. HTH Peter

i see there are map utilities for twinned data.

but before i go try refinement of a twin - will phenix.refine refine against twinned data?

if so, is alpha determined each time, thus, alpha is not specified in the .def?
