ABSORB is a program for Windows to calculate and apply absorption corrections to X-ray intensity data from any source and any detector type (lab or synchrotron, point detector or area detector). Corrections can be made for spherical crystals, and crystals with regular or irregular shapes, and for the effects of absorption and gasket shadowing from diamond-anvil pressure cells. It will handle Rfine and Shelx datafiles.

ABSORB-7 first released in July 2012 contains several significant new features. It includes ABSORB-GUI (shown above), written by Javier Gonzalez-Platas (Universidad de La Laguna, Tenerife) which allows much easier specification of standard experiments. The program that does the absorption calculations has been re-configured to allow it to be called directly from other software as well.

ABSORB-7 and ABSORB-GUI to run it can be installed by downloading and running this installation package. After installation a system restart is performed in order to ensure that the environment variable ABSORB is correctly installed on your system. This variable points to the location of the Absorb executable.

We recommend that you install the programs in a separate folder, and not in the folders where you work on data. The installer will create two sub-folders. One folder has the full users' manual, programmers' guide, and copies of publications, and the other folder has some example files.
