Negative Mouse Reaction Time in Csv on Pavlovia

Online experiments
,
1

In my csv files of Pavlovia online experiments, there are two columns called “mouse_2.x” and “mouse_2.y”. As the experiment has a mouse component, I think they recorded the onset of mouse and the time when the mouse was clicked.

However, for most of the csv files, the numbers of the two columns are negative. I am wondering whether the two columns recorded the onset of mouse and the time when the mouse was clicked. Could anyone help me with this? Thank you so much!

Hey oliver! The x and y tell you the coordinates of the mouseclick. Depending on which units you use they can indeed be negative with that being perfectly normal; for instance with “height” units.
