Calculates new 2D coordinates for the molecule.

Clean 3D

images/download/thumbnails/1805497/clean3D24.png

Calculates new 3D coordinates for the molecule. Clean3D builds up conformers of fragments from which the best, that is, 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
