[open] Timing issue
I'm running an fMRI experiment an therefore the timing is very important. While analyzing the data I realized that I was accumulating ms delays during the experiment that by the en of the experiment amounted to over 2 seconds (which of course means that my analyses were measuring the wrong stimulus. I was able to correct the issue afterwards using all the different timestamps but it would be better to be able o use the planned timed sequence. this means using absolute rather than relative time during the presentation of stimuli.
Is it possible to code the experiment so that stimuli appear as a number of ms from the beginning of the experiment instead of as a number of ms from the previous stimulus?
