Biocrystallography programs
BioMolecular Crystallography From phases determination to final structure

These programs are usually integrated into packages controlled by easy-to-use graphical interfaces (such as CCP4 and Phenix).

CCP4 is an example of the collaborative integration of various programs using a common data format (mtz files). These programs require a minimum of data input from the user, and use numerous default parameters that can therefore replace a user's lack of crystallographic expertise and knowledge. They run on most operating systems (Linux, Windows, MAC OS) and are relatively easy to install. Some references to biocrystallography programs are given in the Software Tools section [Doc. P 1 111].
