RNA Folding Form

Enter the sequence to be folded in the box below. All non-alphabet characters will be removed.
FASTA format may be used.

force bases i,i+1,...,i+k-1 to be double stranded by entering:
F i 0 k on 1 line in the constraint box.
force consecutive base pairs i.j,i+1.j-1, ...,i+k-1.j-k+1 by entering:
F i j k on 1 line in the constraint box.
force bases i,i+1,...,i+k-1 to be single stranded by entering:
P i 0 k on 1 line in the constraint box.
prohibit the consecutive base pairs i.j,i+1.j-1, ...,i+k-1.j-k+1 by entering:
P i j k on 1 line in the constraint box.
prohibit bases i to j from pairing with bases k to l by entering:
P i-j k-l on 1 line in the constraint box.
