[phenixbb] multi-xtal averaging vs twinning

Hi, I'm trying to to figure out how to transfer phases from a twinned SeMet dataset to the native one for refinement. 1) SeMet dataset (2.9A) is solved (despite twinning), structure built, refines 29/35 (ish) 2) SeMet crystals are hemihedrally twinned (confirmed by refining with twin law), native probably too. 3) Native dataset (2.7A) has 5A difference in the long cell edge (478 vs 483A). So I could (and will try to) simply copy the SeMet phases into the native dataset, even though CC Fnat and Fsme is rather low (80-20%). But would phenix.multi_crystal_average know what to do with this? It has no explicit options, so I expected not. Or how *would* one approach this? Cheers Frank
