Buccaneer - Statistical protein chain tracing application
The application developed by Kevin Cowtan from at University of York was recently described in an Acta Cryst. paper (D62, 1002-1011). We have installed it as part of the ccp4, version 6.0.1 distribution. According to Dr Cowtan the application is not strongly sensitive to resolution, but is strongly sensitive to the quality of initial phases. It is therefore complementary to to ARP/wARP, which is more sensitive to the data resolution but could give results with quite poor phases. The method used by Buccaneer appears to be useable at least to the 3.2A low-resolution limit. You are welcome to try it with your data and let us know how it works for you.
