Welcome to the bipartition Web Server

The bipartition server calculates the partition function of two interacting nucleic acid sequences, either RNA or DNA. It only considers intermolecular base pairs (those between the two strands). The output is the estimated base pairing probabilities. Small changes in temperature may cause a substantial difference in the result.
