[solved] Unable to set backdrop in Eyelink 1000 using OS portable 0.27.3
Hi, everyone. First of all, thank you for such a fine and useful experimental solution.
I'm trying to set a simple eye tracking experiment using OS; and, while everything seems to be working fine, I'm not managing to set the stimuli presented with a sketchpad to appear in the host PC, or to be saved to the EDF file.
I'm completely new to eye tracking and OS, and fairly new to python, so I might be doing something wrong.
I've added a couple of inline scripts. One, just after the sketchpad (image_pair) I want to set as backdrop, prepares said sketchpad to be set as backdrop. it goes like this:
eye_canv = self.copy_sketchpad("image_pair") prepared_canv = exp.eyelink.prepare_backdrop(eye_canv)
The other one, just before the sketchpad, only executes in the run phase, and is simply:
The experiment runs fine, but nothing is displayed in the host computer. What am I doing wrong?
I'm using OS portable 0.27.3 with the eyelink plugin (2.8.1 with pygaze gave me a "The Eyelink cannot handle filenames longer than 8 characters" exception), together with an Eyelink 1000.
