MarvinSketch license update - changes in license handling in KNIME

ChemAxon has updated the terms of use for MarvinSketch. As of May 2020, MarvinSketch usage is tied to a license. The license is available through ChemAxon's website, for corporate accounts, for personal commercial, and non-commercial accounts. By updating your MarvinSketch node, you will need a license to proceed. ChemAxon continues to provide free licenses for non-commercial users.

1) In case you already have a MarvinSketch license, activate it in the KNIME node : https://docs.chemaxon.com/License_Installation.html and continue using within your KNIME workflow as you did before.

2) If your company also uses MarvinSketch (MarvinView) for other activities, contact your system administrator and ask him for a MarvinSketch license - which you will be able to install in KNIME nodes as well.

3) Neither you nor your company use MarvinSketch. In this case, you must get a MarvinSketch license. For commercial use please contact sales@chemaxon.com. For non-commercial use, you can ask for a free license here: https://chemaxon.com/products/marvin/download#non-commercial

Please follow the steps of the download page. While commercial licenses remain entirely confidential, ChemAxon collects data on usage patterns of the free, non-commercial users. Please select the relevant option from ChemAxon's download page and let ChemAxon know if you have any questions or comments.

The Marvin Family nodes contain:

 

Marvin Sketch – a power full editor to draw chemical structures, queries and reactions

 

Marvin View – an advanced chemical viewer for single and multiple chemical structures, queries, reactions and non chemical data included in a table

 

MolConverter – Converts chemical structures between industry standard formats like SD File, Marvin, Mol Files, SMARTS, SMILES and others.

 

 

 

Enjoy
