Description

Trying to load e.g. HIFI00023391.nxs_v2 or HIFI00047745.nxs_v2 we get following error: 

Error in execution of algorithm LoadMuonNexus:
Error opening data in group "raw_time"

Tried with latest run data files from EMU, MUSR and HIFI - get this error for all of them. Argus v2 data files in AutoTestData seem to be loaded fine, but I couldn't check any recent real data because there are problems with Argus archive.

  • Blocking 6974 added

(In #6974) First of all, need to investigate why Muon Nexus v2 files fail to load in Mantid for those runs outlined by James Lord:

HIFI00023391.nxs_v2, HIFI00047745.nxs_v2

Ticket for that: #8335

  • Milestone changed from Release 3.1 to Release 3.0

Is actually quite an important one, will try to fit into this release.

  • Milestone changed from Release 3.0 to Release 3.1

After speaking with Adrian and Freddie it seems that something went wrong on data acquisition side. The number of detectors is incorrect as well, as a consequence of the system thinking there are monitors in the instrument. This needs much more rigorous investigation and discussion, so leaving it for the next release.

Muon v2 files are not heavily used by scientists, and all of them seem to have v1 alternatives, so it isn't a blocker problem.

  • Milestone changed from Release 3.1 to Backlog

It doesn't seem that scientists are hugely interested in this one and I am not aware of any progress on fixing version 2 files.

bulk move to assigned at the into of the triage step

comment:9 Changed 7 years ago by Arturs Bekasovs

  • Priority changed from major to minor

Version 1 files are always available, so scientists are not too concerned about that for now.
