Hi, I'm trying to use latest coot-0.7 (4149) and do "Real-Space" refinement, but after refinement the RNA (ribosomal RNA) sugar-phosphate backbone is broke, all the individual RNA residues remain as monomers. With 0.62 version of coot there was no problem to get RNA residues back to polynucleotide form, and you were able to anneal the broken residues by "Regularize Zone". Is there problem with monomer library, as I got restraints for RNA residues from "Get monomer" for Ar, Gr, Cr, and Ur or other reason?
Best, Arto
