Hi Daniela,
The Controller element, as such, is supposed to go inside a trial created with newTrial (previously PennController). In your script, you are trying to use it like a regular native-Ibex definition, which won’t work because your newController commands appear outside newTrial/PennController. If you want to use the old Ibex definition, just build on Option 1 in my first message. If you want to use the Controller element, build on the example I gave in my Edit instead.
Also, I’m not sure what you’re trying to do with your arrays of variable. in the s parameter: what should happen to all those values?
