 ===== When to use =====
-When you are looking for the binding mode or docking score of a particular ligand, [[https://mcule.com/apps/1-click-docking|1-Click Docking]] is an ideal solution to start with. It typically gives you good insights about how your ligand can bind to the target: what critical interactions it forms at the binding site. One step forward is to use the [[Dockingvina|Docking (Vina)]] filter and dock multiple ligands into a single target.

 **1. Conversion of input ligands defined by mcule IDs, SMILES or InChI strings to 2D MOL**
-mcule ID input: The [[Regsys|mcule structure registration system]] automatically associates 2D MOL files with mcule IDs, therefore 2D MOL files can be easily retrieved.

 SMILES input: SMILES string is first converted to canonical SMILES and then to 2D MOL file by [[http://ggasoftware.com/opensource/indigo|Indigo]]. Next we generate a canonical SMILES from the 2D MOL file and check if the two generated canonical SMILES are identical. In case of a mismatch, the ligand is skipped.

 Unknown or undefined tetrahedral stereocenters and cis-trans double bonds are converted into well-defined centers and double bonds by the stereoisomer generator of mcule.

-Conversion is carried out by [[http://openbabel.org|OpenBabel]]. To ensure that molecule conversions did not affect the identity of the molecule, InChI strings of the input ligand and output conformer are compared and in case of InChI mismatch, the ligand is skipped. If the conformer generation fails due to InChI mismatch, another defined stereoisomer is generated in step 2 (if possible).
