Introduction


What is XtalView?

XtalView is a complete package for solving a macromolecular crystal structure by isomorphous replacement, including building the molecular model. It organizes and tracks crystallographic data, maintains log files of the computations, and uses standard file formats to facilitate communication between XtalView and programs such as X-PLOR, TNT, and MERLOT.

XtalView takes full advantage of the modern workstation environment with a simple but comprehensive windows-based interface. It is organized around the concept of a crystal--all data that have a common unit cell and space group. All information for a crystal is kept together in a database file. Nearly all of the data files used by XtalView are in ASCII text and have associated history files to help you track them.

XtalView is described in the book Practical Protein Crystallography, by Duncan McRee, who developed the software at the The Scripps Research Institute. The package is distributed by the Computational Center for Macromolecular Structure, located at the San Diego Supercomputer Center.

What Systems Does XtalView Run On?

XtalView runs under the X Window system and is based on the XView toolkit. It can be ported to any system running an MIT X11 system. XtalView is available on Sun workstations (including the SPARCStation series), Silicon Graphics, DECAlphas, and DECstations running ULTRIX. It is now being ported to the Stardent machines and the Evans and Sutherland workstations.

What Doesn't XtalView Do?

XtalView does not include data collection or protein refinement. For these tasks, we recommend the use of XENGEN or XPLOR, other crystallography software packages publicly available.

To Obtain XtalView

XtalView is free for non-profit use. For-profit users should contact Duncan McRee (dem@scripps.edu) concerning licensing. A binary distribution is available as described below. Source code is also available, but requires a signed license.

To receive information on obtaining XtalView software, send e-mail to:

ccms-request@sdsc.edu

Leave the SUBJECT line blank, and type

get xtalview

in the message.

This is an automated process, and you'll receive a copy of the license agreement and instructions on how to get a copy of the software by return e-mail.

Assistance is provided by email at ccms-help at sdsc dot edu
