Seeing which rows Psychopy uses in excel when randomizing

I randomize the position of stimuli. I introduced x,y coordinates in a excel file. I want to see which coordinates Psychopy use at specific times through the output data. How can I write the code for this and which part should I add it(begin routine, begin exp etc.)?

Hi there,

This info should be auto saved in the output. say your column header is ‘thisLocation’ you should have a corresponding column header for each trial in the output .csv file.
