Download instructions

 

Click on the appropriate link to download the latest version of compressed files for both EXAFS123 and f7f8runner. Programs like WinZip (for Windows users) and MacZip (for Mac Users) can be used to unzip the files. If you are a Mac user and use Stuffit Expander, the .sit file will decompress better. Please read the instructions below for important steps to be followed after downloading the programs.

Important steps after Downloading

 

The unzipping program (MacZip or WinZip) will create a folder containing many files and a few sub-folders. This folder must be renamed EXAFS123 (you may have to remove ".zip" extension from the name) and moved within Igor's User Procedures folder.

 

User Procedures is a sub-folder of the folder on your computer that contains the Igor Pro program.

If you are using WINDOWS (98 or later), the Igor Pro Folder should be listed in the WINDOWS start menu. On a Mac, use the Finder to search (Sherlock) for "User Procedures", and verify that the folder lies within a folder named Igor Pro or something similar.

 

It is recommended that you avoid saving your own files within the EXAFS123 folder. This way, if you download a newer version of EXAFS123, you will not overwrite your work.

 

 

Getting Help

 

Both the applications have help files. If you are a first-time user, you can learn the basics of the program using this Tutorial which is specifically designed to walk you through the steps of using EXAFS123.

 

You can start by downloading some data files. The data given below is for Mn(acetate)2.4 H2O, ground with Boron Nitride and placed in a 2 mm thick sample holder with 1 mil (0.001") thick Kaptan windows. The I0 detector was filled with N2 gas and was 32 cm long; there was an 11 cm air path between the I0 detector and the sample, and 3 mil thickness of Kaptan windows (so a total of 4 mils of Kaptan in the beam path between I0 and the sample). The fluorescence detectors have a deadtime estimated as 5 microseconds. A calibration sample is between the It and Iref detectors (both after the sample), and KMnO4 was used as the calibrant (the pre-edge peak is at calibrated energy of 6543.3 eV; note that the edge shape of the calibration data is not quite right because the "offsets" on the Iref channel was drifting.)

 

 

We will be using the results contained in these data files in the Tutorial.

Version History

 

EXAFS123 was first released on May 12, 2003.( EXAFS123_12_May_2003.zip) ( EXAFS123_12_May_2003.sit)

It was released again, with a few changes, on June 11. (EXAFS123_11_Jun_2003.zip) ( EXAFS123_11_Jun_2003.sit)

The major changes on the later version are:

·         You can change font and font-size in the help files.

·         In the original version, the help display changes according to the actions of the user. For example, if you open the LX Panel, Help topics about the LX Panel are displayed. If you switch to the EXAFS Panel, Help topics automatically change to display topics on the EXAFS Panel. This function is meant to provide appropriate help based on the actions of the user. In the new version, you have the option of letting the help window display topics according to the dialogue boxes you open or keep displaying topics of your choice.

·         Few changes that will make the new version more compatible with the older IGOR PRO versions (3.15).

The revision of November 7, 2003 fixed some minor bugs, and also some major ones in the auxilliary FEFF runner package. (EXAFS123_07_Nov_2003.zip) ( EXAFS123_07_Nov_2003.sit)

The revision of January 14, 2004 fixed some more minor bugs mostly having to do with the deadtime correction routines within LX.( EXAFS123_14Jan2004.zip) (EXAFS123_14Jan2004.sit)

The revision of October 18, 2004 changed the name of one of the help files to be Windows compatable, and also includes a revised "RCS useful macros.ipf" file (although the new useful macros are not used in EXAFS123). (EXAFS123_18Oct2004.zip) (EXAFS123_18Oct2004.sit)

The revision of January 22, 2005 added two EXAFS123 help files explaining the output in the "refinement record" window and how to make tables of results from refinements (EXAFS123 refinement record.ifn and EXAFS123 tabulating results.ifn).

(EXAFS123_22Jan2005.zip) (EXAFS123_14Jan2004.sit)

The revision of March 17, 2005 includes the ability to edit labels for the different data sets and refinement types that can be automatically used in the plot legends (so you aren't stuck with the data folder name). You can also add note that appear in the menus to help you keep straight what data sets and refinement types are which. Some of the help files have been updated, and the use of larger and smaller font sizes in graphs and panels now works better (this is implemented using font size multiplier in the EXAFS123 > Housekeeping > Graph and Table Appearance menu item). There is also a new section of the EXAFS123 main panel that allows you to control what sort of textual information is displayed. (EXAFS123_17Mar2005.zip)(EXAFS123_17Mar2005.sit)

If you encounter any error messages while using the programs, or if you have any suggestions about the programs then please send an email to rscarrow@haverford.edu Most errors occur when routines are run in an unintended order. Learning the basics of IGOR Pro and its programming language will certainly prove helpful.
