Hi Juan, Robert,

OK, I was able to reproduce the problem on a Fedora 23 Linux system with the latest versions of Demeter and Larch.

I can see that the conversion of energy from eV to keV. Clicking different combinations of the Numerator/Denominator buttons can alter the energy by factors of 1000, and is not completely reversible. I see a factor of 1000 as a multiplicative factor in the Energy Text Control window when "keV" is selected, but this appears to not be editable.

I also see that this only happens when using the Larch backend and not the Ifeffit backend. And, I can also see that the energy is being set to the very large value in Larch. So that's a good set of clues to work with.

Hi Juan,

I can open your file. It displays without issue.
My system is amd64 with ubuntu 16.04 LTS.
The version of Demeter I cloned from git is 0.9.26 (using the git clone
instruction), mostly following the 'David Hughes' guide" from here
https://bruceravel.github.io/demeter/documents/SinglePage/demeter_nonroot.html
which seems to be what you found elsewhere.
There were a couple of differences I had to work around:
libpng3-dev had libpng12-dev substituted for it by apt
libgif4 and libwxgtk2.8-dev were not found. I manually installed giflib-5.1.4 and apt installed gtk2.0

I had to ctrl-c out of a loop regarding "can't find apache" when doing ./Build installdeps
(Googling suggests this might be due to perl/build/cpan trying to use mod_perl-1.31 instead of -2.0.4
since 1.31 is slightly newer).

I am still tweaking my system, so this is a fresh install of demeter this morning - no larch yet,
so I get a 'no larch_server' message, but your file displays without issue.

You indicated you have version 0.9.24. What other differences did you encounter?

-R.

Hi,

I send one of the data files we are currently acquiring (SPLINE beamline at ESRF).

I have checked that my compiled 0.9.24 version works with the examples cu10k.dat file, but it is true, as Robert confirmed, that strange things happen if you mark ev instead of kev.

With our data files like the one enclosed, dathena chokes on the scale. Actually it opens the window but it has x10^9 scale. On the other hand, the 0.9.24 for Windows opens the files ok. Now, the files are MSDOS-ended files, I tried converting them to Linux-ending, but same result. I also tried putting a # comment on the first line.

I stress that Athena 0.8.061 (included in the horae package in ubuntu) opens the file like a charm.

One additional detail (just in case), I have Ubuntu 16.04 LTS 64-bit.

Best,

Juan
