I've developed an XOP (external operation) that adds powder and isotropic EPR simulation capabilities to the Macintosh graphing and numerical analysis program, Igor Pro.
Note: You need Igor Pro v2 or v3 to use this XOP!Specifically, the XOP adds:
I've also put together a Demo Experiment (included with the XOP) that shows how the functions work, and also contains some macros to allow for easy editing of parameters.
Grab the files from our ftp server (see links at end of this page). These files are binhexed self-extracting archives.
Interface NOTE: In the PPC version of the XOP, the cursor does NOT spin during a simulation. When running on a PPC this is typically not a problem, as the simulations are very fast. Just keep in mind that during a simulation the mac is completely tied up doing numbercrunching; no backgrounding is possible.
The XOP is email-ware. Please send me a note if you download this XOP and let me know how you like it, how I can improve it, or if you discover a bug.
One plan for the future is to allow Igor Pro to use the XOP in its curve-fitting routines so you will be able to iteratively fit the simulation to an experimental spectrum. I can't say right now when this will be...
