[Market Strategy] GU and AU orientation

Strategy Market Strategy Market - Single State
1

I would like a strategy that says:

  • 2 if purine (R) (Guanine and Adenine) is to the right
  • 1 if pyrimidine (Y) (Cytosine and Uracil) is to the right

Idea background here.

This is for multiloops, in case the closing base pair isn’t GC.
