Need help performing Duplicate Anaylsis


I am currently working on a project along with a few other doctors on the Corona Virus. I am unfamiliar with how to use the Knime software. The doctor I am working under wants me to perform a duplicate analysis as depicted below but I do not know how to. Can anyone briefly describe how to perform the duplicate analysis and the activity cliff analysis.

Thanking you in anticipation,
Anas Hussain

Hi Anas

the workflow that you show in the screenshot is already executed. I can judge that on the green little circles underneath every single box (we call them nodes). That means that the duplicate and activity cliff analysis is already done (if the circle would be red the node would need configuration, if the circle would be yellow it means it’s configured correctly and ready to do its job. A bit like a traffic light). You can check the output/results of every step by rightclicking on the nodes and selecting something with a magnifying glass in the icon.

If you want to run the analysis on new data, you have to change the reader nodes on the left side (rightclick > configure) to get your new data you want to analyse. The green button with the two triangles in the top row then executes the workflow.
However you might need to adjust some configurations.

You might also check out our Youtube channel (, there are plenty of videos about how to use KNIME. If you need more help, check out the event page ( We offer Recap & Office Hours sessions every now and then where you can get help in a one-to-one session.

Best wishes
