Thanks Matt - installing g77 and then recompiling perl/Tk and horae did the
trick!

Bruce - sorry, I meant Perl/Tk...

Paul, you may want to upgrade the installation notes to mention that g77 has
to be installed first. Installion with Fink was a pleasure.

Thanks again guys!

I would add to Bruce's comment that the FEFF.INP file then gives coords
in
terms of angstroms, rather than the cell coordinates ATOMS uses. So if
you
create or modify a FEFF.INP file directly, use angstroms. For an
ATOM.INP
file use cell coordinates.

Hmm...  weird.  I did not know that.

I feel compelled to point out that anyone -- Anatoly, Mark Mark,
*anyone* --
can change the source to feff6L, the version that ships with Ifeffit, to
fix
this or any other user interface shortcoming.  If you do so, let us know
about
it here on  the list so the change (if it's a good one) can be rolled
back
into the Ifeffit distribution.

"And that," he pontificates, "is the beauty of open source...."

Subject: [Ifeffit] rbkg
To: XAFS Analysis using Ifeffit 
Message-ID: 

Hi, I'm a new reader of the list.  Thanks for all this very useful
software and impressive documentation.

I'm having trouble understanding the role of rbkg in spline (or
autobk).  Ravel's Exafs Analysis with FEFF and FEFFIT describes it as
"the cutoff between the portion of the Fourier transformed spectrum
dominated by the background function and the portion containing
information about the local structure".

This would seem to imply that after removal of the background spline,
the signal will have NO frequencies below rbkg -- that is, in the R
domain, it would be 0 (or close to 0) for R < Rbkg.  But this is not
quite what I see; varying Rbkg has a large effect throughout the plot
of chir_mag versus R. In particular I observe sometimes that with Rbkg
= 1.3 (say) I get a very different R-plot than with either Rbkg = .9
or 1.5 -- not just at low R but throughout.  And yet the Rbkg = .9 and
1.5 R-plots look similar to one another, much more than to R-plot for
the intermediate value of R.  Moreover changing Rbkg shifts the peaks
in the R-plot noticeably.

What does the algorithm actually do with this parameter?  It would be
nice to understand that without having to decipher the code.  Forgive
me if this information is given somewhere, but I couldn't find it.

Note: I'm working with compounds for which I don't yet have a good
theoretical model, so I don't know how to choose between Rbkg values
based on the position of the peaks.

Thanks

Hi,

While I had no problem following Matt's instructions to get Ifeffit
working
on my desktop after upgrading to 10.4, I'm still stuggling to install
ifeffit on the new laptop. I've tried different combinations of the
binary
installer  and manual compilations of Tcl/TK and horae, but I run into
this
error:

That would be true if an infinite Fourier transform were possible.
Alas, our
FT is finite (no negative values of k and positive values only go out to
12 or
so).  Since the FT is finite, the Fourier components leak to the left
and to
the right.  In practice, this means that our signal has non-zero
spectral
weight below Rbkg and our background has non-zero spectral weight above
that
value.  Thus, in practice, the background spline and the parameters we
eventually use to fit the data are correlated.

Although there are many things in that document that I would state
differently
today, the language I used to describe Rbkg is valid.  Rbkg *is* the
frequency
we choose as that cutoff, but the cutoff is never as clear as you
anticipated.

All the details of the Autobk algorithm are in Physical Review B47:21
(1993)
p. 14126.

See page 30 in this PDF file
  http://cars9.uchicago.edu/xafs/NSLS_2003/Kelly.pdf
for a nice graphical demonstration of what Rbkg means.  (The rest of
that
document is pretty useful, as well.)

   I thought I would bring up the Wiki entry regarding installation
on Tiger 10.4 at (http://cars9.uchicago.edu/cgi-bin/ifeffit/faqwiz?
req=all#2.12). If there is a problem, I would like to modify the
text.  In short, I have (re)installed horae on two 10.4 systems
upgraded from 10.3 as well as on a brand spanking new dual G5.  It
works without error on each.  For the G5, I installed the new version
of Tk (as explained in the Wiki entry) and then just ran the binary
installer (as I recall).  I don't recall having any problems with the
installation and it works fine on all three machines.  Please excuse
me for mentioning the obvious, but if this a new machine with the OS
pre-installed, it is necessary to install X11 which is an optionally
install on the included installation DVD's.  Once this is installed,
download Tk (tcl is included and does not require reinstallation) and
install it, and then the binary installer for ifeffit.  I don't
recall if the binary installer has the latest version of horae and
ifeffit, but once the base installation is in place, you can upgrade
any time from terminal by typing "sudo horae_update".

No, you don't need to do that!!

What's missing (and we forgot to put it in the instructions) is
that you need Fink's g77 installed as well as the new version of
perl/Tk and the "developers disk", including the X11 libraries
-- I hear these are labelled differently for 10.4, and that
installing XCode might be the best approach.

For Fink, see http://fink.sourceforge.net/.  Using Fink is not
always easy (and requires root access, which for most Mac users
means using 'sudo').  There are reasonable instructions for
Fink, and FinkCommander is a very nice front end to use.  I'm
pretty sure you won't need anything besides g77 from Fink.
It should be that after installing Fink you can open a Terminal
and do:
 ~> . /sw/bin/init.sh
 ~> sudo apt-get -f install g77

Sorry for the confusion,

--Matt
