Hallo, Bruce, Robert. I'm using the 0.9.21 (64)Version with Windows 7. When I try to import the attached file.txt, the warning message appears (see screenshot.png). After clicking OK the file is imported. The log file (dathena.log) and the message (log.txt) are attached. The file from you, Robert, I can read without problem. I would be interesting if the warning message is caused by any strange/hidden signs in the file or some incapability of Win7 with Athena. Thank you for your response, Anna.

Could you provide the file? I have version 0.9.21x64 and encounter no difficulty importing a 2-column text file such as the attached. With regards to your other query, there is a stand-alone version of atoms that came with 0.9.21. It is visible in the windows start menu for me and opens the same window that I get if I try to import an atom.inp or feff.inp from D'Artemis. best regards, Robert On 4/8/2015 4:47 AM, Zimina, Anna (IKFT) wrote: I get the following error message when I read the txt file with two columns of data (energy and intensity): "11:42:20: Use of uninitialized value $line in pattern match (m//) at C:/strawberry/perl/site/lib/Demeter/Files.pm line 188." Still the data can be read. What is the problem?
