Installing buccaneer and parrot development versions: First you should have a licensed, working install of CCP4 version 6.0.99 or later. This 'buccaneer' package contains binaries of buccaneer & parrot compiled for Linux/x86, and distributed as proprietary software. You may install this software for your use within your site for testing and structure solution. You may not modify or redistribute it. This software includes Clipper and kiss-fft, see the accompanying COPYING* files for license details. To install the software, you must have write access to the directory in which CCP4 is installed, and you must have sourced the ccp4.setup file. Then change directory into the directory in which this README is located, and type './install.sh'. -- The automatic installation described above should work. If for any reason it does not, then you could try making the steps manually: cp bin/cbuccaneer_dev $CCP4/bin/ cp bin/cparrot_dev $CCP4/bin/ cp bin/ccp4_pipeline_python $CCP4/bin/ cp html/cbuccaneer.html $CCP4/html/ cp html/cparrot.html $CCP4/html/ cp -r lib/data/reference_structures $CCP4/lib/data cp ccp4i/tasks/* $CCP4/ccp4i/tasks/ cp ccp4i/scripts/* $CCP4/ccp4i/scripts/ cp ccp4i/templates/* $CCP4/ccp4i/templates/ The start ccp4i and select 'System Administration/Edit Task List' Add a new task to the 'Density imrovement' module.
