XtalView is a complete package for solving a macromolecular crystal structure by isomorphous replacement, including building the molecular model. It runs on Sun, DEC, SGI, IBM and PC/Linux computers and takes full advantage of the modern workstation environment. It has a simple but comprehensive windows based interface. The xtalmgr, the main menu drives a suite of crystallographic modules by click of an icon. XtalView maintains log files of the computations done. Standard file formats are used, which facilitates communication between XtalView and programs such as CCP4, X-PLOR, TNT, and MERLOT.

XtalView is described in the book 'Practical Protein Crystallography' by Duncan McRee, who also designed the program.

The CCMS distributes a on-line User Guide 4.0 and a suite of manual pages of XtalView 4.0 package in html.

If you use the programs in work you publish we ask that you reference XtalView with:
