Support-Agglomerative clustering performance [SOLVED]

edited November 2018 in Help
Hello,

I am struggling with clustering processes and more specific agglomerative algorithm.
I have used all the available core studio clustering performances and none method seems to be compatible with the hierarchical clustering...I am always getting errors.
I suppose that I have to combine some other operators to get it work, but I am a beginner and I need help.
Any suggestions?

My process is really simple : 
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.3.015">
  <context>
    <input/>
    <output/>
    <macros/>

    hi,

    what do you want to do in first place? For a simple agglomerative clustering, try this: 

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="6.4.000">
      <context>
        <input/>
        <output/>
        <macros/>
      </context>
      <operator activated="true" class="process" compatibility="6.0.002" expanded="true" name="Process">
        <process expanded="true">
          <operator activated="true" class="text:process_document_from_file" compatibility="6.4.001" expanded="true" height="76" name="Process Documents from Files" width="90" x="45" y="30">
            <list key="text_directories">

              <parameter key="sport" value="C:\Users\vassiliki\Desktop\bbc-fulltext\sport"/>
              <parameter key="tech" value="C:\Users\vassiliki\Desktop\bbc-fulltext\tech"/>
            </list>
            <parameter key="prune_method" value="percentual"/>
            <parameter key="prune_above_percent" value="80.0"/>
