During ratings (4 seconds each), there were some rare but still present cases in the data where participants clicked to lock their response before 3.5 seconds, but moved their mouse 3.5-4 seconds whose trajectories were recorded. The previous code did not consider this scenario and used the first mouse move as the mouse trajectory onset time for all trials. In the case stated here, it will lead to a mouse trajectory onset time larger than the response time, further leading to a negative duration of the mouse trajectory.
In updated codes, the case stated here will have NaN for both the onset and duration of mouse trajectory.
