[mcstas-users] Mantid Nexus export again

[Peter Kjær Willendrup]

Dear Rob,

That should be entirely possible - but an important detail is the use of the min=offset keyword to define pixel enumeration on subsequent monitors/panels.

In the attached I have added an extra monitor_nd like this:

COMPONENT nD_Mantid_1 = Monitor_nD(
    options ="mantid square x limits=[-0.2 0.2] bins=128 y limits=[-0.2 0.2] bins=128, neutron pixel t, list all neutrons",
    xmin = -0.2,
    xmax = 0.2,
    ymin = -0.2,
    ymax = 0.2,
    restore_neutron = 1,
    filename = "bank01_events.dat")
  AT (0.15, 0, 3.2) RELATIVE sampleMantid

COMPONENT nD_Mantid_2 = Monitor_nD(
    options ="mantid square x limits=[-0.2 0.2] bins=128 y limits=[-0.2 0.2] bins=128, neutron pixel min=1e6 t , list all neutrons",
    xmin = -0.2,
    xmax = 0.2,
    ymin = -0.2,
    ymax = 0.2,
    restore_neutron = 1,
    filename = "bank02_events.dat")
  AT (-0.15, 0, 3.5) RELATIVE sampleMantid

And that seems to work for me - see attached graphics.

Best,

Peter

A further question on the Mantid Nexus import/export.
Is it possible to export more than one detector at a time?

I seem to get empty detectors when I import into mantid unless I limit the number to 1.

If not is it planned that this will be available?
It’s a bit tedious running the same simulation with different configurations and then having to somehow conjoin the Nexus data in Mantid.

Additionally, the hdf5 file seems to be appended after each simulation. This rapidly results in a very large file when using events.
Could the append be an option?
