[ccp4bb] Refmac automatically handles twinning?

2022-03-29 Thread Nicholas Keep
Just double checking that Refmac automatically handles twinning without 
the need for a keyword or a box click in i2.  I have a crystal in P32 21 
that gives poor Rfactors and maps (Rfree mid 40s) from what should be an 
excellent model. I have reprocessed in P32, P1 and C2 but all give 
similar results so it appears not to be hidden twinning.  There is no 
need to click a box or enter a keyword for this to be a check for twinning ?


There is severe anisotropy and a few other problems flagged up in iSPYB 
so there may be more complex problems than twinning with these crystals


Best wishes

Nick

[ccp4bb] Anomalous maps from twinned crystal

2022-03-29 Thread Petr Kolenko
Dear colleagues,
We have data from a twinned crystal (merohedral twinning with fraction of 0.71) 
for which we want to see the anomalous map. Could you please guide me how to 
calculate it using the i2? Running refinement with REFMAC5 with merohedral 
twinning does not allow simultaneous generation of anomalous maps.
Best regards,
Petr
