Hi there ! 

I am still very new to RapidMiner without any background in analytics at all. So this is probably a stupid question - still I would very much appreciate your help! 

For my thesis I want to textmine and cluster a series of documents. (In the end I want to create a bubble diagram with different clusters of variabled discussed in the source files)
I created the attached process (according to an approach in a similar thesis) but struggle with the operator: ExtractClPrototypes
The following error displays: 



Any help about how to solve that error will be greatly appreciated.
Thank you in advance !! 

The process looks like this:

    I imported your process xml into RapidMiner, and ran it against a folder of my own text files (since we don't have access to your documents). I didn't get any errors, and all of the Excel files were created and saved. My only guess is that it has something to do with your document files, maybe duplicates? But, I admit it's a weak guess.
