Description#
This algorithm changes the sign of Q and the label of the workspace convention. This should only be used on MD workspaces that contain only Q or HKL dimensions. If there are other dimensions, user should still run this algorithm (so that the convention flag is changed), but then run TransformMD with -1 for the non-Q dimensions.
Usage#
Example - an example of running ChangeQConvention with PointGroup option.
mdws = LoadMD('MAPS_MDEW.nxs')
dim = mdws.getXDimension()
print("X range of Q {} {}".format(dim.getX(0), dim.getX(1)))
ChangeQConvention(mdws)
mdws = mtd['mdws']
dim = mdws.getXDimension()
print("X range of Q after ChangeQConvention {} {}".format(dim.getX(0), dim.getX(1)))
Output:
X range of Q 0.0 10.0
X range of Q after ChangeQConvention -10.0 0.0
