Same as ADDSYM + transformation & Plot of new averaged structure in new space group.
Following is an example ( ex3.spf) taken from the Cambridge Crystallographic Database of a structure published in the orthorhombic space group Pbca with one molecule in the asymmetric unit which transforms easily to the cubic space group Pa-3.
The structure in the orthorhombic description looks a shown in Fig1.
Either by clicking on 'ADDSYM-PLT' or with the instruction CALC ADDSYM PLOT it will be shown by PLATON/ADDSYM that a better description of the structure in the cubic space group Pa-3 is possible (Fig2) with only 1/3 of the molecule in the asymmetric unit.
The non-conforming hydrogen atoms on the methyl moiety are either disordered or misplaced in the original model.
