OMG - I've ignored them in my .coot.py file ... This explains the strange mt rotamer with (-65, 51) without correction by Coot. However, if I let Coot correct the nomenclature errors, the mt rotamer on the same leucine looks okay, now, and the externally measured Chi angles are indeed (-65, 175), but "Edit Chi Angles" in Coot displays them as (-65, -61). Could you please check this? Best regards, Dirk.
