Duration of stimuli presentation

[mynamewh]

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!

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), ``` Matlab 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)
