 When we start this simulation McStas should now automatically output an Instrument Definition File with a .xml extension containing the minimal information required by Mantid to lay out the instrument. If we want to include all components then we can run from the mcshell:
 
 * Windows: `mcdisplay-pl templateSANS_Mantid.instr --format=Mantid -n0 --complete`
 * Mac/Linux: `mccdisplay templateSANS_Mantid.instr --format=Mantid -n0 --complete`
