Adds a function to correct task data from an early version of the tablet touch app, where
cursoris set to NaN & disappears whenever there is no touch input. This causes problems becauseuser_screenis also set to NaN (to indicate there was no touch). When bothcursoranduser_screenare NaN, there is no continuous signal that can be used in frequency domain analyses.In later versions of the touch app, the cursor remains visible at the last valid position until the next touch input. In both versions,
user_screenis set to NaN whenever there is no touch. This function updates thecursorfield in task data to always be non-NaN after the initial touch input and uses theplant_visiblefield to indicate whether the cursor was shown or hidden.I've re-preprocessed tablet data w/touch app and checked that it works as expected.
