Dear Phenix users, I am trying to solve a big RNA/protein complex at 5A resolution. Phases come from MR solution with a partial model in Phaser. Thanks to NCS the map after density modification in RESOLVE is of reasonable quality for this resolution and new secondary structures, out side of the model, can be detected. I would like to improve the maps and model with something like a poor man's version of AutoBuild. An Autobuild for very low resolutions that does not include refinement but iteratively carries out density modification and identification of helices/strands outside of the model with phenix.find_helices_strand. Does this sound feasible, Are there already scripts the follow such a scheme ? Many thanks in advance for your advice -- Peter
