Hi Julius,

Your original email from last month came while I was on travel.
Happily someone else helped you get over the immediate problem, so
this issue has been languishing on my back burner. I finally got
around to looking at it this morning.

The next release of the software will fix both of the problems you
observed:

1. The "add a site" button was broken and should work in the next
release.

2. The problem you had with your original crystal data will still
happen. Robert's solution was the correct one. In the next
release, a situation like yours will fail more gracefully and
Artemis will issue a (hopefully) useful error message.

Thanks for reporting your problems to the mailing list. It really
helps make the software better.

I should also point out what an excellent advertisement for the
mailing list your original email was. I was out of the country and
unavailable, so it's a good thing you didn't try to contact me
directly. Because you used the mailing list, someone else was able to
help you. That's a system t hat works!

Hi everyone,

Did anyone figure out how to fix "Can't call method tag" error and
adding sites? Really a novice on fitting and I badly need help on this
to get going. Sorry to bother everyone.

Thanks!

Julius

Hi Chris,

Yeah, I did try "add a site" but it is not responding. Does anyone
else experience this problem? Thank you, Chris.

Julius,

While I am not certain what the error means, there is a button
displayed right above the atom list which says "ADD A SITE." I
would suggest that having a unit cell as large as you do, along
with rather weak scatterers such as N, C, O, and I assume H, it
is probably unnecessary to have sites beyond the 3rd shell or so
since these contribute negligibly to the EXAFS.

Hi Bruce,

Here's the screen shot of my work in ATOMS. It's supposed to
be more than 7 atoms in the core column but that's also one
thing I do not know how to add change and add more atoms.

When I click "Run Atoms", it gives me this error "Can't call
method "tag" on an undefined value at
C:/strawberry/perl/site/lib/Demeter/Atoms.pm line 668.'' I am
using the recent version 0.9.18.2 of the Demeter installer.

Thank you for your help!

Julius
