Analyzing information for each cluster

Hi,

I would need help and advice for this problem with RM. I am trying to cluster in 5 clusters and get the topic of scientific documents (I have it in PDF and in TXT and I tried with both so the format is not the problem). As you can see in the process after extract cluster prototypes I try to separate each cluster to analyze the most common words in every cluster and exctract the topic of them. I would like to filter the words, for example the ones that appear less than 0.01 using  select attributes or remove useless attributes, but this operator is not working. I have to transpose the rows and then I can remove the words that have 0 value adding another operator filter examples. I tried to add text to nominal because I thought maybe RM does not detect that the frequency after separate the clusters is a number, but still is not working.
I hope you understand the proleblem. I write the code below.

    I don't know why is added an emoticon when I write the code.
