Hi Gyuchul, Have you tried using Stand Alone Atoms (it comes with the demeter package) instead of webatoms? In my experience, stand alone atoms should not have a problem with 10 angstrom cluster. Hope this helps, Cecilia -----Original Message----- From: Ifeffit On Behalf Of ifeffit-request@millenia.cars.aps.anl.gov Sent: Wednesday, November 20, 2019 12:00 PM To: ifeffit@millenia.cars.aps.anl.gov Subject: Ifeffit Digest, Vol 201, Issue 11 Send Ifeffit mailing list submissions to ifeffit@millenia.cars.aps.anl.gov To subscribe or unsubscribe via the World Wide Web, visit http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit or, via email, send a message with subject or body 'help' to ifeffit-request@millenia.cars.aps.anl.gov You can reach the person managing the list at ifeffit-owner@millenia.cars.aps.anl.gov When replying, please edit your Subject line so it is more specific than "Re: Contents of Ifeffit digest..."

I got the atomic configurations of molybdenum from molecular dynamics simulations, and I'd like to import it into FEFF 9. In order to do that, I converted lammps file into cif file, and I am trying to convert cif file into feff.inp. I am using Webatoms to convert cif file into feff.inp. The default value of cluster size and longest path is 8 and 5, respectively (in angs). However, when I try to increase the cluster size and the longest path to 10, it stops working, and I got the internal error. I am working with 1024 atoms (8x8x8 cells, bcc crystal structure). Are 1024 atoms too many to deal with in webatoms? or is there other ways to convert cif file into feff.inp? I don't have any problems when I use the ideal cif file (not from molecular dynamics simulations). Sincerely, Gyuchul Park
