Hi all, I've been having some difficulty using FEFF8 generated files with Artemis. Here's what I've tried: I've run a somewhat modified version of FEFF 8.28 on a Mac. It generates files as it should (I've used them with feffit before). I open Artemis...I've tried on a pc running Windows XP, and on a PowerPC Mac running OS 10.4.9. In both cases, the result was similar. After opening Artemis, I choose "New Feff input template," and then "Import feff.inp." I choose the feff.inp file from the folder where I ran Feff. I ask for just the first path, and I get an error (this one's taken from the pc): Use of uninitialized value in pattern match (m//) at /PerlApp/Ifeffit/Path.pm line 1623. main::_ANON_('Used of uninitialized valye in patern match (m//) at /PerlApp/If...') called at /PerlApp/Ifeffit/Path.pm line 1623 Ifeffit::Path::pathlabel('Ifeffit::Path=HASH(0x2195580)', 'Path %i: [%p]') called at artemis line 6150 main::fetch_nnnn(data0.feff2', 'C:\New ifeffit 2\horae\stash\artemis.project.1\data0.feff2', '._feff0001.dat') called at artemis line 340 eval {...} called at /PerlApp/Tk.pm line 340 Tk::MainLoop() called at artemis line 2127 The result is that although the feff.inp screen in Artemis looks fairly normal, the "Data & Paths" screen just shows "Path 0:[]" beneath the new feff calculation. I can also try adding a new path from under the theory menu and I get a similar response (different line numbers in the error message). I've never tried bringing a Feff8 calculation into Artemis before. Is there something obvious I'm doing wrong? I've attached the feff.inp file and one of the path files to aid in diagnosis. --Scott Calvin Sarah Lawrence College
