Clean 2D

Calculates new 2D coordinates for the molecule.


Clean 3D

Calculates new 3D coordinates for the molecule. Clean3D builds up conformers of fragments from which the best, i.e. the lowest energy conformer is given back. The quality of the structures is measured by a simple energy function (Dreiding type molecular mechanics).


Convert to Aromatic Form

Transforms the molecule to aromatic representation using the transformation method set.


Convert to Kekulé Form

Transforms the molecule to non-aromatic representation.
