[Ifeffit] Exchange Dirac Hara on Artemis

Dear Dr. Bruce Ravel,

Thank you for your quick reply.  If my problem is using Artemis, do you
mean I should not use Run Feff under Artemis [Feff] Atoms and Feff, if I
want to incorporate Exchange 1 0 0?

My other approach was running the feff.inp on feff6 and have it calculate
all the paths with Exchange 1 0 0.  Is this the solution you have in mind?
 However, when I am in Artemis 0.9.13, I cannot find the option for Artemis
to pull those pre-calculated paths into the project file.

Kind regards,

Siri

There's your first problem.

Dear Dr. Matt Newville,

Thank you for your quick reply and attention to my inquiry.  I have change
the exchange card so that it has only 3 numbers: EXCHANGE 1 0 0.

Please find attached the input file, feff.inp.

To replicate my error, please:

- open this data file in Artemis 0.9.13 and
- refer to Artemis [Feff] Atoms and Feff
- click Run Feff

You should see the following error report:

Feff executable: C:\strawberry\c\bin\feff6.exe)

 Feff 6.01l

 Token            0

 See FEFF document -- some old features
 are no longer available.

Hi Siri,

Hmm, not sure -- running feff6L with exchange 1 works for me.   The
exchange card only takes 3 numbers (index v_real v_imag).

If you're still having troubles, please send a complete input file, plain
text format, or the complete project file.   Sending the full plain text of
the output you get would be helpful too.

In general: Please don't send screenshots -- they're too hard to read and
don't tell the whole story.  We're willing to help, but it's very hard for
us to guess what might be going on with a partial story.

--Matt
