HI, Bruce and Matt I have two questions for you, please help me. 1. I collected U EXAFS data on APS 10-ID, while I input a single data file with reference data in Athena, it was OK, however, when I input multiple data files (scans) also with reference data, it was crushed. I could input multiple data files without reference data, which Matt helped me trouble shoot. The Demeter 8.24 version is used on my computer, I believe. Matt suggested me to update to the current version. I do not know if other users have this problem. 2. I have a U EXAFS data file which was collected at SSRL, however, I could not input this data file using Athena, how to fix this? format? See the attachment. thanks you so much.
