i am trying to extract timings of events in my e-prime experiment and e-data files and make sense of them.
I have a fixation point at the very beginning of the procedure:
it has a small delay
than i have my PicDisplay.OnsetTime timings.
My question would be: If i have any Delays are they accounted for in OnsetTime or should i subtract them from those timings before choosing given time during data analysis.
In other words, to give you an example:I know that my first event of interest should start 24 seconds into the procedure.
My timings are:
Fix1.OnsetTime : 44856
Fix1.OnsetDelay : 39
My first event of interest is:
XX.PicDisplay.OnsetTime : 69056
What should be my accurate pic display time for SPM or any otherstatistical software. Should i account for delay or this information (Fix1.OnsetDelay : 39) is mainly informative?
What if PIcDisplay has his own delay?
I would be grateful for your help with this interpretation.
