[Ifeffit] correlating number of nearest neighborst to the particle size

Hi All,
I would like to estimate the size of Cu nanoparticles grown in my sample by EXAFS fitting. I can refine the number of nearest neighbors in these Cu nanoparticles up to 4 shells (say NN1, NN2, NN3 and NN4), by constraining S02 to the value obtained by fitting the data of Cu reference foil. But, how do I correlate the refined values of nearest neighbors to the actual size of Cu nanoparticles ? Any help in this regard would be much appreciated.
Regards,
Jatin

Dear Dr Ravel and Demeter users,
I recollect that the Athena and Artemis user guides used to be available as PDF files (which I found useful). Am I correct that the latest guides are now only accessible as internet pages, as I can't seem to find a download link?
Best regards, Leon

I just put links to PDF copies of the two Users' Guides on the Demeter home page: http://bruceravel.github.io/demeter/
A couple things to note:
1. When you install either from source or from the Windows installer,
full HTML copies of the users' guides get installed as well.
2. The PDF files are generated from the same source as the html. I
have spent a lot of time making the html look reasonable. (Not
great, but reasonable!) The PDF are pretty rough and have some
obvious layout problems. But I just skimmed through both of them.
They are usable, though certainly not beautiful.
Thanks for asking. I had stopped updating the PDF versions because I didn't know that anyone was using them. How 'bout that!

Hello Bruce and thank you for your hard work!
instructions to install on OS X 10.6.8?
There is not a Mac package. I do not own a Mac and and so do not have the ability to develop a Mac package on my own.
Over the years, no one has ever stepped up to help me develop a Mac package for Demeter. (Or Debian packages, or RedHat packages, for that matter.)
Well, I have *tried* many times, and put a fair amount of time in
getting Demeter to work on a Mac. What I have not done is *succeed*.
I can tell you that getting wxPerl to work on Mac OSX is far from simple. Though Demeter is many years old now, and I've tried many times over the years (and I using wxPython on Mac all the time), it is only within the past few months that I have ever gotten wxPerl to actually build on any Mac, and this was a 10.8 machine. Currently (though I haven't looked at it in more than a month), getting the Ifeffit-Perl interface to build properly with Mac OS 10.8 has me stumped, as Apple is now using llvm/clang, making it challenging to work well with gfortran.
Migrating Demeter to use Larch should simplify the situation, as it would remove the need for the Ifeffit-Perl interface.
Frankly, the work I do on the Windows package takes a lot of time. The only way I can claim that time fits in my job description is because my group uses Windows machines at our beamlines. Help would be welcome to develop packages for Mac and other platforms, but despite repeated requests over many years, no one has ever volunteered and actually seen it through to completion.
Yes, help building Demeter for Mac OSX would be great.
I too have put a lot of work into making Demeter run on OS X. I have been attempting to make a port of it in Macports [1] so it is easy to install and/or have a package installer created.
The good news is that along the way I have successfully created a port of ifeffit [2] that builds fine for me on 10.9 and should work all the way down to 10.6. I utilize gcc for gfortran. I believe the ifeffit-perl bindings [3] work too. After you install Macports [4], you can simply type:
sudo port install p5.16-ifeffit
The bad news is that my in progress Demeter port does not work yet. The problem I?m stuck on is getting the perl-wx port [5] built. I have not been able to get it built with the new wx-widgets version 3.0.0 that is in Macports. The perl-wx people apparently don?t have support for that version of wx yet and they never respond to my queries about it on the mailing list.
I encourage people to test out ifeffit on OS X through Macports and give me feedback - positive or negative. Thanks to Bruce for his support during this endeavor.
Cheers!
Frank
