(In [12900]) Extend event loading to handle ISIS files. Refs #3274

comment:2 Changed 9 years ago by Freddie Akeroyd

(In [12902]) Fix test. Refs #3274

comment:3 Changed 9 years ago by Freddie Akeroyd

(In [12903]) I think this test was using the wrong data file and so broke when I made the check in LoadEventNeXus stricter. Refs #3274

comment:4 Changed 9 years ago by Martyn Gigg

(In [12904]) Refs #3274. Ensure that the custom spectra-detector mapping can be found.

(In [12906]) Minor fixes for loading ISIS style event files needed for WISH. There was a bug surrounding monitors and spectra that didn't show up with LET as the bug only shows when the monitors are at the start, as with WISH. Re #3274

(In [12907]) Add a WISH event NeXus file for testing. Re #3274

Has events, histograms, and monitors. Instrument view OK. Logs are not loaded correctly

comment:11 Changed 9 years ago by Martyn Gigg

Viewing the NeXus file with HDFView gives me 14 log entries and once loaded I can see these from the right-click 'Show Logs' option in MantidPlot.

Works for SNS. Logs for ISI show 0. see ticket #3280

Andrei, thanks for checking all this - the WISH00002868.nxs file has only detector data in it (it was generated from an existing histogram raw file WISH00017713.raw and i didn't bother with the logs). When we have a proper instrument run on WISH we will upload a real file. Regards, Freddie
