Finding symmetry elements in P1

There's a program called zanuda (by Andrey A. Lebedev) accessible at http://www.ysbl.york.ac.uk/YSBLPrograms/index.jsp , and available from CCP4 6.4, which is meant to identify the true spacegroup based on refinement of models expanded to lower symmetry, or picked after transformation to higher symmetry. This allows one to solve a structure in P1 and then decide afterwards what the symmetry really is.
