Description (last modified by Nick Draper) (diff)
When doing homering (transformation to energy) for ISIS instruments, you are getting resulting ws with correct source position in it:
mem = mtd['calculated.spe'] s = mem.getInstrument().getSource() print s.getPos() Result: [0,0,-1.65] : CORRECT
=== after saving this workspace in file and loading it again, the source position is lost:
mem2 = mtd['loaded'] t = mem2.getInstrument().getSource() print t.getPos() Result: [0,0,0] : WRONG

From Alex:
Save was NeXus switch selected in ConvertToEnergy algorithm.
AFAIK -- SaveNexus algorithm.
LoadNexus for load correspondingly.
