Hairpins ordered by length
Sequence-based queries may include
ambiguity codes. Internal loops and multibranched loops can be

For a query sequence of N bases, the input range is [0,N].
default value of 0 will be used when ambiguity codes are present in
the query sequence or the input is negative. Similarly,
N will be used if the input is larger than the length of
the query sequence.
Enter a 4-character pdb id. The search may be restricted to an individual chain,
by attaching ':chain-id' (e.g., 2tra:A), with '%' matching any chain.
