[Ifeffit] Solution to running Demeter on an ORNL computer

[Matt Noerpel]

Hello Dave,

Writing to the list to update my situation
<http://www.mail-archive.com/ifeffit%40millenia.cars.aps.anl.gov/msg05272.html>
with the EPA computers was on my list of things to do today.  While we are
both likely dealing with security issues, I don't know if this is the same
problem we were having.  We could not run Demeter even with admin
privileges.  The only possible way it would run was in safe mode.

My solution was to follow Matt's instructions
<http://www.mail-archive.com/ifeffit%40millenia.cars.aps.anl.gov/msg05386.html>
to install Anaconda Python and Larch (which I apparently didn't need admin
privileges for) and run Demeter with Larch as the backend instead of
Ifeffit.  DAthena opens using Larch, but I am having issues with some
features.  Mainly the LCF does not work quite right, but I'm not sure if
that is just a problem with the reference library I am using or due to the
issue on the Demeter to do list: "Use of stdev array in LCF is slightly
incorrect, needs to be sensitive to the space in which the merge was made."
 Rebinning all the references in DAthena seems to help, but it still
doesn't work for fitting in k space.

DAthena also runs on the slow side compared to old Athena on my work
computer and DAthena on my personal computer which uses Ifeffit, but that
could just be these computers.

I am using the 0.9.23 pre3 release.  Hephaestus and Artemis also both open
using Larch, though I haven't tried to use them.

Thanks,

Matt
