Report the count of rows after several filtering operations

Hi everyone

I am doing a workflow for virtual drug screening and I would like to report the total nr. of molecules (essentially row count) at different steps in the workflow. E.g. at the beginning when loading in the dataset, after different following filtering operations as the nr. of molecules decreases when i remove duplicates, missing values, filter on different molecular factors etc.

Does anyone have a hint to the easiest way to do this with the “data to report” node?



Hi @Soren_Therkel

Another user had a similar request some time ago. Have look around in that topic, some ways to approach this are described in there. Hopefully it provides some inspiration:
