Sharon, yes, you do need SSRL plugins to import SSRL files. It is because Athena expects to have X-ray energy as the first column, whereas SSRL data files have time as the first column. Open Athena, click on Main Window, find Plugin Registry and enable all SSRL plugins. Good luck, Ned ________________________________ From: Ifeffit [ifeffit-bounces@millenia.cars.aps.anl.gov] on behalf of Bone, Sharon Elizabeth [shbone@lanl.gov] Sent: Monday, May 01, 2017 2:18 PM To: Ifeffit@millenia.cars.aps.anl.gov Subject: [Ifeffit] Error importing data into Athena Hi, I’m running the current version of Athena on a windows 10 machine. It had been working fine, but now I get an error whenever I try to import new data (.dat file from SSRL). The error tells me the program can’t read the file and asks whether I need a plugin. Do I need a plugin? How do I uninstall and reinstall the program? I’m guessing this might be the best fix? Thanks! Sharon
