SINGLE
SINGLE is a control program for four-circle diffractometers equipped with point detectors. It is especially optimised for precise determination of lattice parameters from single crystals, but will perform intensity data collections and other types of scans and diffraction measurements on single crystals. It handles the restrictions on diffraction from crystals held in a variety of furnaces and diamond-anvil pressure cells.

SINGLE runs under WindowsXP and Windows7. It drives the Huber SMC9000 and SMC9300 controllers, the Stoe Stadi4 and the Siemens P4 motor controllers. It is installed and used in many single-crystal laboratories around the world. The software can also be run in "dummy" mode without a diffractometer to do diffractometer calculations off-line. If you have other diffractometer controllers you want to automate, or requests for new features, please contact us by e-mail.

The program is described in an article published as Angel and Finger - 'SINGLE: a program to control single-crystal diffractometers'. Journal of Applied Crystallography, 2011, 44, 247-251. A reprint is available as a pdf file, Copyright © International Union of Crystallography.

Download a zip archive that includes the program, auxiliary files and manuals. Extract the installation guide and read it for instructions as to how to install and configure the software. The installation guide also includes examples of how to configure your diffractometer hardware. If you would like help in installing this software on your diffractometer, please contact us.

If you download and use Single, please register with us by e-mail, so that we can inform you of new releases and updates of the software.

Last Update: 26-Oct-2015. This includes full implementation of intensity data collection, and a very important bug fix. If you are using an older version, please upgrade to this version; old versions will not be supported. If you are upgrading from a previous version of Single 2014, you only need to extract the executable and replace the previous version, and extract the new manuals. See the User's manual for details.

Important: If you are upgrading from Single 2010, you must perform a new installation as described in section 2 of the Installation Guide in the distribution zip. This is because Single 2014 has a lot of improvements, new features, bug fixes, and was ported to a new Fortran compiler.

The development of SINGLE-2014 was supported in part by ERC grant 307322 to Fabrizio Nestola. To learn more about this project go to the INDIMEDEA project web site.

If you have been using WinIntegrStp to process your data from Single2010, please download the latest versions of that program as well to process data from Single2014!
