Hi!
I'm a new user of RapidMiner and I'd like some help for exporting the Tree model rules in some formats.

I think "Tree to rule" is a good solution, but I dont know how to link it to my model and if it's the right solution....

Any suggestions would be really appreciated. ;)

Thanks again

C.

    Hi cristiano,

    you can export the model into xml which can further process: 
    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.0">
      <context>
        <input/>
        <output/>
        <macros/>
      </context>
      <operator activated="true" class="process" compatibility="5.0.8" expanded="true" name="Process">
        <process expanded="true" height="296" width="547">
          <operator activated="true" class="retrieve" compatibility="5.0.8" expanded="true" height="60" name="Retrieve" width="90" x="45" y="75">
            <parameter key="repository_entry" value="//Samples/data/Iris"/>
          </operator>
          <operator activated="true" class="multiply" compatibility="5.0.8" expanded="true" height="76" name="Multiply" width="90" x="179" y="75"/>

          <portSpacing port="sink_result 1" spacing="0"/>
          <portSpacing port="sink_result 2" spacing="0"/>
        </process>
      </operator>
    </process>
