Sorry, I've just seen that this has already been reported. Ian
From: Godfrey, Ian Sent: 27 January 2016 11:21 To: 'XAFS Analysis using Ifeffit' <ifeffit@millenia.cars.aps.anl.gov> Subject: Data summation - missing groups Dear All, When using the data summation tool in Athena (0.9.24 x64 on Win10 Pro) the first group in the group list seems to be missing from the dropdown showing the potential components of a summation (see attached screenshot). To reproduce: 1) Open attached project file and import with "select all" on the import dialogue box 2) Change to data summation window 3) Try and add the first data group (234) to the summation from the dropdown menus. (In the screenshot I've changed the default normmu(E) to mu(E), but the same behaviour is displayed in both cases.) On a related note, I'm not sure I fully understand how the data summation is different from the merge? Clearly data summation allows you more control (arbitrary weighting of groups etc.) and is intended for XANES analysis, but is it a fundamentally different procedure or just a different interface for the same thing?
