rework of the User Interface for plotting. The text based, command line
input has been replaced by an interactive GUI that allows for immediate
feedback of changes made to plot or calculation parameters. Please
check it out!
In an effort to allow XDAP for Windows users connect and share their

May 2009:
A bug fix for Version 3 of XDAP for Windows has been released.
March 2009:
Version 3 of XDAP for Windows has been released. The most important new feature is the
ability to do Data Reduction for up to 10 files at the same time using an already Data Reduced
file as a template.
Upgrade pricing can be found in the licensing section.
Oct 2008:
An updated demo of XDAP for Windows has been posted.
May 2008:
An updated demo of XDAP for Windows has been posted.
The current version number for XDAP for Windows
is still 2.2.7. Work on a new feature that facilitates analysis of
QEXAFS and / or DEXAFS measurements is continuing. In order to
streamline product development and speed up implementation of new
features the decision was made to discontinue the XDAP versions for
MS-DOS, MacOS, UNIX and Linux effective immediately. However, these
products will continue to receive support . A new license and upgrade fee schedule has been posted as well.
September 2006:
Work on a new feature that facilitates analysis of QEXAFS or DEXAFS measurements has started.
May 2006:
The current version number for XDAP for Windows is 2.2.7. There have been a number of bugfixes since January 2006. Work on several new features has started. Let us know at info@xsi.nl if you have suggestions or wishes.
January 2006:
The current version number for XDAP for Windows is 2.2.6.
There have been a number of bugfixes since June 2005 and part of the Help files has been rewritten. Licensed users
can request an updated set of Help files.
Mulitple
Shell Analysis has been expanded with the ability to fit third and
fourth order cumulants in every shell. This is of particular importance
for analysis of spectra measured at room temperature or above.
There
is the usual set of bug fixes and interface improvements. An
improvement in the conversion of files with just energy and absorption
to the internal XDAP format should also be mentioned.
January 2005:
The current version number for XDAP for Windows is 2.1.5.
September 2004:
XDAP for Windows
has received a number of interface enhancements and several bugs have
been fixed. The Help function (not available in the Demo version) now
works correctly. The current version number for XDAP for Windows is
2.1.4.
May 2004:
XDAP for Windows
has received a number of interface enhancements and several bugs have
been fixed. Support for datafiles from the Photon Factory (Tsukuba) and
Spring-8 has been added.
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.
November 2003:
A new XDAP for Windowsdemo has been released. Bug fixes and small improvements have taken the version number up to 1.3.18.
A routine to convert FEFF chi.dat files to XDAP .CHI files was added..
Increases the number of points that can be deglitched to 50.
Averaging of .INI files is back by popular demand.
Besides these new features there are numerous bug fixes and interface
improvements, particular in the Multiple Shell Analysis section.
February 2002:
Version 1.2.0 of XDAP for Windows
has been released. Several new GUI features have been added. Among
these are file selection. Another important new feature is the option
to compare five sets of background parameters as EXAFS, FT, background
or derivatives of the background.
September 2001:
An updated demo of XDAP for Windows
is available. This demo will expire on December 15, 2001. Besides a
number of bug fixes, it contains a new GUI for XANES analysis. Try it
out!
June 2001:
Over the past few months
several bugs have been fixed and a couple of new features have been
added to the background subtraction GUI. A new version of the XDAP for
Windows demo has been made available.
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.
December 2000:
The demo of the Windows version of XDAP is now available! The familiar
menu structure has not disappear alltogether, but where appropriate
menus and dialogs have been used to make XDAP easier to learn and use.
It is possible to print to any windows compatible printer. For more
information click here.
June 1999:
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.
August 1998:
The demo of XDAP is now available in a native PowerMac version. Go to the download section to retrieve your copy.
In
the process of the development of the PowerMac demo a couple of
glitches and omissions in the 68K FPU demo were discovered and
corrected.
