Column 1: trial number
Column 2: internal timing of trial
Column 3: coding for position of start and end location (1 is rightmost combination; 3 is leftmost combination)
Column 4: x position on touchscreen for start location
Column 5: y position on touchscreen for start location
Column 6: internal timing of reach onset
Column 7: stimulus intensity (multiply by 0.00316 to convert it to peak to peak displacement in mm)
Column 8: internal timing of reach end
Column 9: response to tactile stimulus (1 is detected; 2 is not detected)
Column 10: x position on touchscreen for end location
Column 11: y position on touchscreen for end location

x direction is along the participant’s mediolateral axis
y direction is along the participant’s anteroposterior axis
