# ChemDraw

ChemDraw is a [package](https://datagrok.ai/help/develop/develop#packages) for the [Datagrok](https://datagrok.ai) platform that registers PerkinElmer's ChemDrawJS molecule sketcher as one of the sketchers available through `grok.chem.Sketcher`. Once installed and licensed, it appears alongside OpenChemLib, Ketcher, and other registered sketchers wherever Datagrok prompts the user to draw a structure. The sketcher exchanges structures in SMILES, MOL V2000, MOL V3000, and SMARTS notations.

ChemDrawJS is a licensed PerkinElmer product. A valid license XML URL must be provided through the package's `LicensePath` setting; without it the sketcher displays "Licence is not available" and will not load.

## Installation

1. Install the latest version of the ChemDraw package from npm via the **Packages** tab in Datagrok.
