Hi Ralf This is in relation to refining RNA/DNA structures. I'm basically trying to duplicate the restraints specified in http:// cns.csb.yale.edu/cgi-bin/cns_solve_1.2/cns_view.cgi?&file=inputs/ auxiliary/dna-rna_restraints.def. Basically, in RNA A-form helicies the sugar pucker is restrained around 3 angles, and the atoms of the bases must be planar.

Hi Francis, Currently we don't support what you are looking for; sorry. geometry_restraints.edits would be the place to look, but you'll find only bond and angle. I didn't get to the other restraint types. However, in theory you could work with .cif files, although it may be a bit cumbersome. Could you explain in some detail which atoms you want to restrain? I'll put the geometry_restraints.edits.planarity support up higher on my todo list.
