I experience the problem that the column names which I can pick for Reactant 1 are replicated to the Reactant 2 pull down menu, regardless of what I connect to input port 2. This allows basically to only use the same input table at input port 1 and 2. Or as a work around, one has to rename the column for Reactant 2 in the second input table.
workflow is attached. Workflow data should be included. I use the reactions defined by Hartenfeller et. al. which should be already in reaction SMARTS format. However, I couln't get them to work directly thus I am converting them to RXN using the ChemAxon MolConverter.
I am using KNIME 2.5 with latest nightly build of community nodes.
I also just tried this update. I do now find the correct columns in the node dialogue, but I get the following error after configuring the node (with a reaction SMARTS):
reaction should have exactly one reactant. It has: 2
Is this a bug in the node, or am I misunderstanding?
I get the same message using reaction SMARTS. Thus I converted the reaction SMARTS into RXN format using the free ChemAxon MolConverter. The RXN column can then be connected to the third input port of the Two Component Reaction node. Use a row filter to keep only the RXN you are interested in.
My attached workflow above has all the above steps in it.
