First of all thanks for the amazing dataset, it really is full of useful information.
I am working on the neuropixel data and I am trying to track the pupil movement of the mouse over the screen to compensate for the saccade when estimating the receptive fields of units. I noticed that through “session.get_screen_gaze_data()” (where session is “cache.get_session_data(<session_id>)” I am able to get the raw_screen_coordinates_x_cm and for y. However I was wondering a couple of things:
Are the raw screen coordinates found in the get screen gaze basically the coordinates of where on the screen the mouse looks at?
What is the reference point of these measurements. Are these measurements taken with respect to the centre of the monitor or one of its corners or even an external reference point?
How big is the screen? I have seen on the white paper it says width of 21.93 inch while on another thread on this forum it says 53.3 cm which are different. (By the way, the screen should be 1920x1200 even though the natural movies have a much lower resolution, am I correct?)
When you get the natural movie stimulus, what you obtain is what the mouse should have seen taking into account that the image on the screen was warped and that the mouse field of vision “warps it back” am I correct? So there is no need to apply a mask to the natural movie when estimating the receptive field since the return of the function get_natural_movie_one is effectively what the mouse sees?
I am sorry if I have asked so many questions, but I thank you in advance for your time and much appreciated consideration.
(PS: I know there is a question with a similar title asked already, but effectively there is no answer to the particular questions I am asking)
