'Parrot' is a density modification/phase improvement program, designed as a replacement for 'dm', but more automated and using up-to-date methods. On my JCSG test datasets I get 10% more model built and sequenced after parrot than 'dm', and yet it is runs almost as quickly. Parrot also features automated NCS averaging, using operators from either heavy atom positions, or from a MR or partial model. This code is significantly more reliable than the version in pirate, and faster too.
Warning: this new version of buccaneer requires a pre-release version of CCP4 6.1.. Test releases 6.0.99c or later should be suitable. The binaries are available for Linux(x86), MaxOSX(x86), and MacOSX(ppc) (only the Linux version is supported).
Note: This package will also install the latest version of the 'buccaneer' model building software.
The software includes Clipper and kiss-fft, see the accompanying COPYING* files for license details.
After installation the graphical user interface should be available at the bottom of the 'density improvement' module.
For normal calculations, an MTZ file and sequence are required. For NCS averaging, a file of heavy atom coordinates or a partial model are also required in order to determine the NCS operators.
