The current version number for XDAP for Windows is 2.1.2.

January 2004:

Two exiting features have been added to the Multiple Shell Analysis option of XDAP for Windows, the first is the ability to fix the ratio of parameters, the second is the ability to fix the sum of a set of parameters. Fixing the sum of parameters (particularly coordination numbers) is really useful if one knows the structure of the surroundings of the absorber and needs to determine the size of the particle / domain. Fixing the sum of a set of parameters is important when one analyses the relative ratio of one or more neighbours to the absorber.
Another big change is the implementation of a full menu structure to select the various options of XDAP for Windows. This allows easier access to the full power of XDAP.
There have also been a number of bug and interface fixes. Current version number is 2.0.3.

April 2001:

XSI has made another step in making XDAP more userfriendly and EXAFS analysis less time consuming! Everybody who has ever seriously analysed EXAFS spectra of diluted samples knows that dealing with glitches is a major time consuming step before data analysis can even begin. With the new deglitch GUI of XDAP for Windows this step has become a breeze.
The zoom function is now completely graphical, but the possibility to enter exact data ranges has been retained.

It is possible to print to any windows compatible printer. For more information click here.

An option to batch process data files has been implemented. This is extremely usefull in doing Data Reduction on multiple spectra of the same sample. It will also proof handy in the analysis of Dispersive EXAFS experiments.

November 1998:

Principal Component Analysis (PCA) for XANES, EXAFS and Fourier Transforms have been added to the already extensive analysis capabilities of XDAP. A nice introduction to the use of PCA in XAS is given in the paper by M.J. Fay et al., Mikrochimica Acta, 109 (1992) 281 - 294.
