[Ifeffit] Is there a Artemis User's Guide like the Athena?

Hi Kefan,

I suspect that my answer to this question will be of broad interest,
so I am taking the liberty of CCing the Ifeffit mailing list.

Thank you for the very kind words regaridng Athena.  I am pleased that
you found the Athena User's Guide so helpful.  Sadly, I have not yet
written a document of comparable extent for Artemis.  I certainly
understand that there is a need for comparable user guide, but finding
the time and energy to write one has not yet happened.  Writing the
Athena User's Guide was fairly exhausting and I need to take a break
before embarking on a similarly large document for Artemis.

I have to defend Shelly's various presentations.  I think they have a
lot of good information in them.  I think that using them along with
other resources can give you enough of an overview of Artemis to get
started.  I strongly recommend that you work through Scott Calvin's
ZnO example, which can be foun at 
   http://cars9.uchicago.edu/iffwiki/HoraeSoftware#contrib
ZnO is somewhat of an idealized example -- many of us work on
problems that are pretty far removed from a simple crystal like ZnO.
However, Scott's example is quite thorough.  Working through it while
carefully following his comments in the project journals will
introduce many of Artemis' features.

As for the pod file -- those are the files that get displayed when you
click on one of the documentation buttons from within Artemis.  I
acknowledge that they are thin on details and somewhat out of date.

The last bit of advice I can give you is to read the papers written by
the names you see on the Ifeffit mailing list.  The folks who offer
answers to question on the list are also some of the best
practitioners of EXAFS analysis using Feff.  Although it might seem
funny to read papers by Anatoly Frenkel or Paul Fons if you are
studying environmental science (or Shelly Kelly's if you are a
materials scientist), I strongly recommend doing so anyway.  Their
science might be pretty far away from what you do, but the EXAFS
analysis strategies are quite instructive and are certainly
transferable.

I know that is not the answer you were hoping for, but it may be
helpful nonetheless.

Regards,
B
