Hi Craig,
I'm cc'ing this to the Ifeffit mailing list, as others may encounter
similar problems.
It's not your novice-ness that's causing the problem; it's a version
issue. I wrote the ZnO example when an older version of the software
was current. Since then, "dr" became a reserved variable, and can't
be user defined. (Bruce could probably give the reason for that
change.) I fixed that, but it looks like the older version of the
tutorial is being included with the current distributions of Ifeffit
and friends. We'll fix that. In the meanwhile, though, you can just
change the variable names by hand to "delr" or something like that
(you have to change them in both the GDS screen and the path screens,
or course). Sorry about that.
Incidentally, there's a related bug in Artemis itself. If you have it
automatically come up with variables for you on a new fit, it will
name one "dr", and then can't do the fit! :(

Dear Scott,
Sorry to bug you on what may be a very trivial issue - but if
its a quick fix a bit of guidance would be very much appreciated.
I've been working through your ZnO demo tutorial on Artemis and
everything worked well until I received the following warning message from
Artemis after trying to Fit at the beginning of part 2. The Fit then aborts.
"This parameter uses a name which has special meaning in Ifeffit:
dr
You must change this parameter name before attempting to fit.
One common example of this sort is a variable named "dr1", which
should be changed to something like "dr_1" or "drone"."
The warning message doesn't make a great deal of sense as "dr" is a defined
parameter within Artemis.
Running ifeffit-1.2.9-mac10.4_horae64pre_pkg on a Mac PPC G5 Dual 2GHz under
OS X 10.4.8. Presumably I'm doing something dumb (very much the novice EXAFS
is not my area). Have checked a number of the Ifeffit Archives, but so far
have not spotted a reference to this.
Kind Regards
Craig Klauber
