Marvin JS as molecule sketcher in webportal: license required?

Java applets are now deprecated and Chemaxon stopped availability of Marvin Applet

We switched the KNIME webportal molecule sketcher from Marvin sketcher to MarvinJS skecher.
But MarvinJS skecher shows a "Valid license cannot be found" message in the webportal.
We tried the GGA ketcher, but it doesn't satisfy our needs.

Is a dedicated Marvin license required in order to use MarvinJS as sketcher in KNIME Web portal?

Thanks in advance,


It looks like you need a license. But in order to be really sure, you should ask someone at ChemAxon. We are only providing the sketcher extension as a convenience for users.

You can contact them directly by following this link.
