Description:
development environment for CCP4 compatible programs
The goal of the ggp4 project is to provide a standalone replacement for the CCP4 library for macromolecular crystallography. The library performs a number of common tasks in standardized manner. These tasks include file opening, parsing keyworded input, and reading and writing of standard data formats for electron density maps and X-Ray diffraction data. Programs may call this library to ensure compatibility with the CCP4 program suite, as well as a similar look-and-feel. . This package provides the FOTRAN API library for developing free CCP4 compatible programs.
