Good to hear that. :-)
In regard to the rpm’s - where did they point? and where would you have liked to have them point? (Then there is a chance things will be OK for 2.2… ;-) )

Thanks Peter,
That worked.
Incidentally it still took a bit of hacking to install mcstas 2.1 from rpm.
The soft links still point at some strange places.
Thanks again
Rob

Subject: Re: [mcstas-users] mantid output test
Dear Rob,
You have indeed stumbled across a proper bug - it seems what I implemented in mcdisplay for generation of the IDF implicitly assumes n>1 bins… :-) I will test for the special case of n=1 bins in the next released mcdisplay.
I am able to generate the IDF and NeXus output if I define an event monitor with 2x2 bins which loads OK into Mantid.
(My Mantid then on the other hand crashes when I attempt to show the instrument… This may or may not be my recently updated Mac OS X Yosemite, not clear…. - But “color fill plot” can be done)
Best,
Peter

Hi,
I’ve been brave and tried the Mantid output option in mcstas this morning.
I’m using mcstas 2.1 and mantid 3.2.1 on a Redhat 6.4 box.
There seems to be no problem with the installed NeXus and hdf libraries the simulation runs fine.
The problem comes when I try following the instructions to generate the IDF file.
This is the simple instrument I’ve tried some of the variables would be picked up in later components.

The xml file resulting from this when I run the command
mcdisplay --format=Mantid Test_Mantid.instr -n0
after compiling chucks out this message
Illegal division by zero at /usr/local/bin/mcdisplay line 391, <IN> line 73.
And proceeds to dump an enormously long xml file with a huge number of weird repeated components.
Any hints as to what is messing things up would be greatly appreciated.
Thanks
Rob
