SpectrumList not working for LoadISISNexus data

[Anders Markvardsen]

Running the following (using data from

ws = LoadISISNexus('LOQ49886.nxs')
print ws.getNumberHistograms()
ws = LoadISISNexus('LOQ49886.nxs', SpectrumList='5,6,9')
print ws.getNumberHistograms()

produces the output

17792
17795

where the expected output would have been

17792
3

Note that LoadMuonNexus gives the right output, i.e.

ws = LoadMuonNexus('ARGUS0026287.nxs')
print ws[0].getNumberHistograms()
ws = LoadMuonNexus('ARGUS0026287.nxs', SpectrumList='5,6,9')
print ws[0].getNumberHistograms()

produces the output

192

This may be fixed im #9989

[Federico M Pouzols]

This works for me. Alex is right that #9989 must have fixed this ticket. I checked with LOQ49886.nxs and other files (see below), and variations of the example command using 'SpectrumList' always produce the expected output.

To test:

• check that you get what you expect from commands like

  ws = LoadISISNexus('LOQ49886.nxs', SpectrumList='5,6,7,9')
  print ws.getNumberHistograms()
  

  => should print 4 (length of SpectrumList)

You can also check other files, like systemtests/Data/LOQ/LOQ74014.nxs, systemtests/Data/INTER00013460.nxs, or systemtests/Data/SANS2D/SANS2D00000808.nxs.
