Hi @Paria_akhdari and welcome to the forum. I moved your topic to the KNIME Analytics Platform category since it’s large and gets more visibility.

About your question: you haven’t provided much detail about what you want to do, so it’s hard to say. But I can recommend searching the KNIME Hub for workflows involving clustering. Here’s one that might be helpful to get you started:

The blog post associated with the workflow is here:

Best, Ael

Thanks again @Daniel_Weikert ! I very much appreciate it ! … and it motivated me to eventually put in place a possible solution [image] 20211201 Pikairos Handling missing value in clustered data.knwf (687.0 KB) @m1k here you have a workflow which should answer your second question. I did not use a set with missing values as reference but if you replace the data set used here by yours with missing values, it should do the job. Otherwise, let us know and we will amend it. H…
