PubChem nodes


According to this link

there should be PubChem nodes available, but I can't find any information on how to install these.

Please advice!

Look at the "More community Contributions" section in the following page for the latest URL:


i followed the topic and also downloaded the newest community contributions package (zip archive).

Does somebody have an idea what might be the problem`?

Hi @Alkaline -

To fix this, make sure that you have enabled the KNIME Community Extensions (Experimental) in KNIME -> Preferences -> Install/Update -> Available Software Sites:

Then you should see the CIBI extensions appear when you search for “PubChem”:

Thank you :slight_smile: This worked!

it seems that page is not available anymore. The link takes directly to KNIME hub but not trace of the original tutorial. Does anyone have a copy of it by any chance? thanks!
