Hello,
I am having an issue with getting the correct timestamp for the most recent gaze coordinates. I have used two different functions to get the latest gaze coordinates. These functions are
1. [samples, events, drained] = Eyelink('GetQueuedData' [, eye])
2. [sample, raw] = Eyelink('NewestFloatSampleRaw' [, eye])
The issue I am having is that the timestamp of the latest gaze coordinates saved in the samples(1,end) acquired using 'GetQueuedData' is different than the timestamp of the sample.time acquired using 'NewestFloatSampleRaw'. I run these two functions one after another and the difference between the timestamps is sometimes around 500ms. What can be causing this problem? Has anyone had this problem before?
Kind Regards,
Berk
