ovrnafold |
Please help by correcting and extending the Wiki pages.
It reads RNA sequences, calculates their minimum free energy (mfe) structure and output the mfe structure in bracket notation and its free energy. It produces plots of the resulting secondary structure graph and a "dot plot" of the base pairing matrix.
The original program has additional inputs and produces different outputs, depending on the options selected. In the EMBASSY implementation it is split into ovrnafold for a single sequence and ovrnafoldpf for a pair of sequences
