Hi,

I’m trying to do an experiment that combines eye tracker.
For this reason, I tried to load and run the “stroop_eyetracking demo” for inspiration.
In the README file is written "Please edit the config file to set the display parameters and eye tracking parameters so they are valid for your setup."
I’m using SMI iView system so I edited the “SMI_iview_std.yaml” file but when I’m trying to run the experiment I get an Error:

I’m attaching the edited file: what I have done wrong?
