Hi, when I refine a ligand with hydrogens in coot using realspace refinement, the hydrogens explode into the surrounding density. This only happens with ligand/cif files generated in elbow and not libcheck. Coot apparently needs and additional loop in the .cif file: _chem_comp_tree.xxxx, which is missing from the elbow output. Unfortunately the geometry generated by libcheck is pretty dismal, so I can probably get around this by running libcheck on the refined coords from elbow ... Nigel, is it possible to fix elbow for the next rc? PS I am running the latest phenix (rc6) and coot 0.33 if that helps. Cheers Carsten
