Information for PsychoPy Users
The CABI facilities are set up to support PsychoPy experiments. Depending on the demands of a given experiment, users may need to create their experiments in one of two possible versions of PsychoPy. These versions piggyback on the restart system that CABI employs to allow for switching between E*Prime versions 2.0.8 and 2.0.10.
Video Experiments – PsychoPy 10.1.80
Users who wish to present any kind of video stimuli in PsychoPy must currently build their experiment(s) in PsychoPy version 10.1.80. This is due to a known problem in the more recent version that causes video stimuli to break when running the experiment. To run this version of PsychoPy, start the computer system on the E*Prime 2.0.8 version.
Stimulus Resizing – PsychoPy 10.1.83
Users who are dynamically resizing their stimulus images using the “WIDTH” and “HEIGHT” attributes may find that a warning is produced upon all or most stimulus presentations notifying the user that the stimulus may not be in the expected aspect ratio. In version 10.1.80, this warning message itself is broken, which will result in experiments breaking any time a stimulus must be resized. Version 10.1.83 has fixed this warning; it will still show, but will not break the experiment. To run this version of PsychoPy, start the computer system on the E*Prime 2.0.10 version.
