== 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 author of the program package is Wolfgang Kabsch (Wolfgang dot Kabsch at mpimf-heidelberg dot mpg dot de). | |||
The program is free for academic use, and can be downloaded from http://www.mpimf-heidelberg.mpg.de/~kabsch/xds/html_doc/downloading.html (if the download from that site fails, there's a copy at ftp://turn5.biologie.uni-konstanz.de/xds ). | |||
Documentation is at http://www.mpimf-heidelberg.mpg.de/~kabsch/xds or [http://strucbio.biologie.uni-konstanz.de/~dikay/XDS_html_doc/index.html here]. | |||
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). | |||

== Purpose of the Wiki == | |||
The purpose of this Wiki is to provide an accurate resource for XDS users, and to provide explanations and hints for the successful use of XDS. I (Kay Diederichs) try to keep the Wiki up-to-date with XDS versions and insights. I collect [[Tips and Tricks]] for XDS usage, explanations of its output, and recommendations for the parameters in [[XDS.INP]] (if it appears useful to deviate from their defaults). | |||
To see what's there already, go to [[Special:Allpages|List of all pages]]. A good starting point is the article about [[XDS.INP]] where the keywords and parameters for running XDS are described. There is also a [[wishlist]], and [[Known Bugs]], and [[Quality Control]] (under construction). | |||
== Contributing to the Wiki == | |||
* The MediaWiki software used here works in the same way as the well-known Wikipedia. This means that anyone can read articles, but for editing existing pages, and creating new ones (this happens automatically when you click on a [[red link]]), you need a [[Creating an account|userid and password]]. Due to the amount of spam created by abuse of Google mail accounts, we are no longer allowing account creation for @gmail.com email addresses. | |||
