Hi,
I’m currently trying to program an experiment on Superlab 4.0, however there seems to be a freezing problem between trials.
Each block of my experiment (15 blocks in total) consists of 8 trials, each containing 360 JPEG files (a lot, I know) with a cue superimposed throughout. The 360 JPEG events are each displayed for a 16ms, resulting in the appearance of a continually spinning object (120 images result create one complete spin).
The events within a single trial run smoothly, however I was expecting the transitions between trials to be smooth also - this does not appear to be the case…
As opposed to the object continually spinning for the duration of the experiment between blocks and trials, there is a 4 second freeze between trials in which Superlab is unresponsive - even if I press escape, it waits until the next trial has begun. On top of this issue, which is literally doubling the length of the experiment, the software takes approximately 5 minutes to start running it!
I’ve experimented with the memory management option (i.e. loading all files before or between trials) but to no avail. Also, it doesn’t seem to be a problem related to the memory of the PC as I can multi-task during the running of the experiment, i.e. to operate explorer, etc. As such, I’m stuck as to how to resolve, or improve, this issue…
Any ideas anyone?
