"Conditional Restraints": Restraining the Free Atoms in ARP/wARP.
Amsterdam, Netherlands. In Structure, 2009
In the ARP/wARP approach, model building is facilitated by initially interpreting a density map with free atoms of unknown chemical identity; all structural information for such chemically unassigned atoms is discarded.
A knowledge-driven approach for crystallographic protein model completion.
Netherlands. In Acta Crystallogr D Biol Crystallogr, 2008
The average root-mean-square deviation of the C(alpha) atoms in the loops built during validation was less than 0.4 A. When implemented in the context of automated model building in ARP/wARP, Loopy can increase the completeness of the built models.
