NOSYMM TOGGLE

When this option is active (i.e. shown RED), No symmetry expansion is done in the geometry calculations.

This toggle has effect only when activated before any explicit or implied CALC INTRA instruction is executed.

No symmetry expansion can be useful when the application of symmetry relations results into undesired infinite networks in the subsequent analysis.

Similarly, undesired infinite chain expansion is avoided in the ORTEP display.
