 The "Prepare" (middle) window allows you to define your experiment through and [http://mytestbed.net/projects/omf/wiki/OMF_Main_Page OMF]  experiment script specified in [http://mytestbed.net/projects/omf6/wiki/OEDLOMF6 OMF Experiment Description Language] (OEDL).
 
-At the top of that window is a text field which you can use to search for existing OEDL scripts. Type "GEC20" in the field and then select "GEC20-learningswitch.oedl" from the list of files that are offered.
