Duration of stimuli presentation #11

Open mynamewh opened 6 years ago

mynamewh commented 6 years ago

Hello! Sorry to bother you. I ran vistadisp on Ubuntu 16.06 with matlab 2014a. I found the duration of stimuli is shorter than expectation. For example, when I set type=8 bars, TR=2.5s, period=360s, question appeared: [showScanStimulus]:Stimulus run time: 289.054455 seconds [should be: 359.937500]. The stimuli presented correctly, just the duration was wrong. I checked the codes and fresh rate of my monitor, they are just fine. I am very confused about that, could you help me? Thank you very much! WH

Hello WH, did you find out what the problem was? I ran into the same issue, it seems like some of the stimulus cycles get skipped. Best, MN

Hi All,

If you want to debug, I suggest calling your experiment from the command line, then saving the params file and posting it.

For example, you can do the following (or something like it),

params = retCreateDefaultGUIParams;
params.fixation    = 'dot with grid';
ret(params);

And then post both the code you ran and the saved file (which should be on your Desktop)
