Handling time resolved data
Dear Bruce, Recenetly we did some time resolved measurements, QEXAFS mode. While the old Athena arranged the file as we want i.e file 1, 2, 3 etc, the new did it bit different 1, 11 12 and again 2, 21 etc. Screenshot attached. Why is it doing diffrently for the two version? Can it be fixed some how. Thank you, Ditty -- Ditty Dixon, Anorganische Chemie Karlsruhe Institute of Technology Kaiserstr 12 Karlsruhe, Germany Ph no: 004972160848093
I think you just need to rename the spectra with a '0' in front of the single digits and it will order it correctly. Do this in advance when collecting more data.

You haven't explained exactly where these data come from, so I am assuming that each scan was written to its own file and these files were imported into Athena. In Athena, data are imported in "ascii-betical" order, that is, sorted in order of characters in the ASCII chart: http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters In that sense, Athena sorted your data as expected. As Chris pointed out, if you want things like nr_1.spec nr_2.spec ... nr_10.spec to sort numerically by the number between the _ and the .spec, you need to format the them so that numerical and ascii-ordered sorting come out the same. This is done as nr_01.spec nr_02.spec ... nr_10.spec For a quick exafs experiment, two digits is probably not enough, so you'd want something like nr_00001.spec nr_00002.spec ... nr_00010.spec I don't recall quite how the sorting worked in the old version of Athena (it has been over 5 years since I stopped working on it), but my vague memory is that, on Windows, they were imported in the order that they were clicked upon the file selection dialog. The way it is currently done is much better in that it is reproducible. -- Bruce Ravel ------------------------------------ bravel@bnl.gov National Institute of Standards and Technology Synchrotron Science Group at NSLS --- Beamlines U7A, X24A, X23A2 Building 535A Upton NY, 11973 Homepage: http://xafs.org/BruceRavel Software: https://github.com/bruceravel
