How to extract transistor terminal coordinates ?

Hi,
How can I extract the coordinate of transistor terminals from cadence in the layout?

For one transistor which has <B,S,D,G> terminals, I need four rectangle coordinates that contains these terminals. For example, G(Gate) is a rectangle of poly located in (10,8) (12,8) (10,18) (12.18). For multi-finger transistors, I need all finger coordinates.


Thanks for your help
