Re: [Ifeffit] FW: Data summation - missing groups

Having said that, I've downloaded and applied the patches from github and have found a slightly annoying behaviour. Everytime I use the the buttons under the plotlist (both the orange ones and the purple ones) the component lists reset. i.e. I set up a sum with component 1 as, say, HAuCl4 standard and component 2 as, say, Au foil and plot it. I then plot a couple of datasets using the buttons on the RHS. At this point all the component lists reset themselve to blank. I can reselect the component from the dropdown easily enough, but this is annoying if I have several components set up with corresponding weightings in a summation.

Sorry, I've just seen that this has already been reported.

Indeed: http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2015-November/008320.html This problem will be fixed whenever the next version of Demeter comes out. I apologize for the inconvenience in the meantime. B

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?

Thanks,

Ian
