== What is XDS, and how to obtain it? ==
XDS is a program package written for the "reduction" of 2-dimensional data images ("frames") obtained from crystals irradiated with monochromatic X-rays. The package mainly consists of the programs [[XDS]] (which processes a single dataset), [[XSCALE]] (for scaling of several datasets) , [[XDSCONV]] (for conversion of output file to other formats) and [[VIEW]] (for visualizing).

The package mainly consists of the programs [[XDS]] (which processes a single dataset), [[XSCALE]] (for scaling of several datasets) , and [[XDSCONV]] (for conversion of a reflection output file to other formats). Additional auxiliary programs are [[cellparm]], [[2cbf]] and [[merge2cbf]]. [[XDS-viewer]], for visualizing frames, can be downloaded separately (see [[Installation]]).


The author of the program package is Wolfgang Kabsch (Wolfgang dot Kabsch at mpimf-heidelberg dot mpg dot de).

Since version 30-Jan-2009, the format of the control images written by [[XDS]] (and [[XSCALE]]) [http://www.mpimf-heidelberg.mpg.de/~kabsch/xds/html_doc/Release_Notes.html changed]. An open-source viewer [[XDS-Viewer]] is [http://xds-viewer.sourceforge.net available]. Latest versions of [[Adxv]] can also visualize XDS output files.

There is another program available, which serves to produce additional output of tables and plots. This is not part of the official XDS package; its name is [[XDSSTAT]] (written and distributed by Kay Diederichs).

A graphical interface (beta) to XDS is available, that allows processing of multiple datasets with minimum user effort. It is called
[[XDSGUI]], a graphical user interface, serves to help using XDS.
