NetLogo: How to ask to turtles who on the cells except the origin cell?

I want to ask to turtles who on the cells except the origin cell (x, y) = (0, 0) in one-dimensional cells spaces. The following is sample code, however, this syntax includes the origin cell (x, y) = (0, 0). Any other ideas if you have, please advice here. Thank you.
