Re: [Ifeffit] Error in Running XANES on FEFF8.4 for Cobalt based cluster (Joshua Kas)

1 Sep 2015

      Dear Josh,

Thanks for the altered input. It seems fine now as you mention. I ran the
XANES calculations and compared with the existing literature of
experimental XANES and it looks good.

Thanks again,

Ganesh

Hi Ganesh,
It is common to see the
WARNING:  TWO ATOMS VERY CLOSE TOGETHER.  CHECK INPUT.
warning from feff when you have H atoms since the bonds tend to be very
short. However, these are not the ones that are causing the problem. These
warning can be ignored if the structure is reasonable. If the structure at
the bottom of this email is the input structure that you used, then there
is indeed an oxygen atom that is less than 0.1 angstrom from a carbon atom,
which is of course unphysical. That is probably what is causing the
problem, however, there are some other things that could be causing
problems as well. In particular, there are what I like to call "floating
atoms" in your file, i.e., single atoms or several atoms that are
disconnected from the rest of the cluster. I am sending a new input file
below that has fixed this problem. I  deleted the O atom that was too close
to the C atom, and deleted all of the structure that wasn't connected to
the central atom by a string of bonds. You might worry about weather the C
or O atom is the one that should have been deleted in the structure, but
you can always test using both possibilities. I doubt that it will make
much difference since C and O look pretty similar, and the O atom is pretty
far from the Co. Also, the H atoms look a bit messed up, but I don't think
that will make much of a difference either. You can check by taking the H
atoms out and running and see if the results change much.
Cheers,
Josh Kas

Dear Bruce,
Thanks for the response and sorry for the delay in getting back to you.
I retried the FEFF simulation using structural information from another
article (Randaccio, Lucio, et al. *Inorganic chemistry* 39.15 (2000):
3403-3413). The structural data from this article seems to be widely used
by many others in simulating for optical absorption. But here with FEFF,
I
still run into the same issue of "ATOMS VERY CLOSE TOGETHER" and a couple
of other issues. With two different articles suggesting smaller bond
distances for a few of their atoms, it seems like the distances are what
they are.
I have attached the log files and input file for this trial run.
Is there any way to circumvent this error without altering the structure
?
Thanks,
Ganesh

tried the FOLP with the recommendation for Hydrogen of 0.8, I seem to
get a syntax type error, that i cant figure out. I checked the
crystal
structure and the smallest hydrogen bond distance is 0.89 A. (I have
attached the corresponding input and log file with suffix 'full

In Feff the "TWO ATOMS VERY CLOSE TOGETHER" message gets shouted at you
when you have atoms that are separated by 1.75 Angstroms or less.  That
message has nothing to do with the FOLP setting.
...
2. *SCF for small cluster*: Since the problem with the hydrogen
distances persisted, I decided to run the calculation for a smaller
cluster (about 50 atoms). I used the conditions as prescribed for
small
clusters - SCF 5.0 1, FMS 5.0 1, RPATH -1. Those hydrogens that were
too
close (within this smaller cluster, there were about 3 of them, and
none
in the first or second shell of co-ordination) were removed manually.
Now, I did not have the error on distances, did not require the FOLP
card to be manually altered, but the log1 file seems to suggest that
the
SCF is not calculated. I cant figure why that is the case. (I have
attached the corresponding input and log file with suffix 'small
cluster')
When I ran feff 8.40, I got same the contents of the log1.dat file, but
with these additional lines:
Core-valence separation
   WARNING: fatal error in subroutine corval. Try
     to reduce ca1 in SCF card. If does not help,
   SEND bug report to AUTHORS
   CORVAL-1
I don't quite know what that means, but it gives some hints.  The
source
code corval.f tells us that is "Finds the core-valence separation for
the cluster of atoms."  I simply am not knowledgeable enough about the
details of Feff to know why your cluster triggered this warning.

Oops!  That message is triggered for atoms separated by 1.75 bohr,
which
is about 0.92 Angstrom.

Message-ID:

Dear Ie-Rang,
I?m the demeter maintainer on MacPorts, but I admit I am anything but a
MacPorts guru.
I notice that the error you showed is a failure to install gcc49. I
don?t
know if that new GCC is compatible with your old version of OS X, but
that?s an issue that?s beyond my expertise. You might edit your
variants
file (it?s /opt/local/etc/macports/variants.conf on my installation) to
insist on an earlier version by adding a line containing, e.g.,
?+gcc47?
or
whatever is your installed and preferred version of GCC.
In fact, the port demeter does not depend (directly) on gcc, which you
can
see by issuing the command
...
port echo depof:demeter
port echo depof:demeter-devel
So it looks to me like you have several steps to get ready for
installing
demeter.
I admit that I recently discovered?but have not fixed?a flaw in the
demeter port description file. The code depends on ports
p5.16-file-which
and p5.16-math-round, but these are not made explicit. I need to figure
out
how to add these to the explicit dependency list. I?m just back from
vacation and a conference, so I have no excuses now. If you get far
enough
that you can install *but not run* demeter?s executables, then a
workaround
for this is
...
sudo port install p5.16-file-which p5.16-math-round
And for MacPorts users in general: I understand that the project as a
whole is in the process of trying to move to Perl 5.22 instead of 5.16.
I?ll be updating the port file to reflect that change, too.

Hello,
I'm trying to install MacPorts package on my mac (v.10.6.8), and I
can't
do this. Below are error messages that I got.
Could you please help me to figure out what the problem is?
Thank you.

Perhaps there's anything useful in that log file?
