Hello!
I was curious what controls the dropdown options for the renderer to image node.
For example, I see that some people have the RDKit as an option. However, my node does not have that option, but I have Indigo and Marvin as options (no Marvin license, fyi).
Any help would be appreciated.
Thanks,
Angie
Hi @chemgirl36
You need to install RDKit to have its renderer added to the list of molecule types recognized by the -Renderer to Image- node.
If you grab one of the RDKit nodes from the KNIME hub, the following one for instance :
and you place it on your workflow, KNIME will suggest to install RDKit. Once the plugin is installed, you will see the RDKit option among the Renderer options of the -Renderer to Image- node.
Hope it helps.

This is partially why I asked the question. I do have RDKit nodes installed. Maybe I should have led with that 
I appreciate your response nonetheless.
Just a double check. If you open the table of other nodes that have molecules in your workflow, can you see the “RDKit 2D Depiction” option like in the snapshot below?
I do not see RDKit 2D depiction as an option. I wonder if I do not have all of the RDKit nodes because I do not see anything regarding 2D for RDKit in my repository.
Double checking again:
If you click on “Help” → “About KNIME Analytics Platform” → “Installation Details”, in the “Installed Software” tab list, do you see an entry called “RDKit node feature”, as follows:
Yes - mine looks exactly like yours
In this case, I believe the RDKit renderer should be available in the -Renderer to Image- node.
Did you add a -RDKit from Molecule- node before the -Renderer to Image- node, as follows:
Otherwise, you may not get the “RDKit renderer” option among the renderers even if RDKit is installed.
Maybe this is why. Hope it helps.

YES! That’s it! Thank you! I knew it had to be “operator error” LOL
