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
