Dear all Hello again.
We have another protein-RNA dataset which we are trying to refine. For this dataset we have three OMU nucleotides modelled. We got the monomer from Coot 'Get Monomer'. Refmac returned the following error: ERROR : atom :OP3 OMU 2 CCC is absent in the library ERROR : atom :OP3 OMU 3 CCC is absent in the library The library version is 5.44. I tried to download a OMU.cif (from this link https://www2.mrc-lmb.cam.ac.uk/groups/murshudov/content/refmac/Dictionary/dictionary.html) for use in Refmac but the same error occurs. So... what should I try now? Many thanks in advance!
