Function

   Secondary structures of RNAs with partition

Description

   This is a port of the Vienna RNA package program RNAfold.

   The original program has additional inputs and produces different
   outputs, depending on the options selected. In the EMBASSY
   implementation it is split into vrnafold for a single sequence and
   vrnafoldpair for a pair of sequences See the original documentation
   for the Vienna RNA package http://www.tbi.univie.ac.at/~ivo/RNA/

Algorithm

Usage

   Here is a sample session with vrnafoldpf

Author(s)

   This program is an EMBOSS conversion of a program written by Ivo
   Hofacker as part of his VIENNA package.

   Although we take every care to ensure that the results of the EMBOSS
   version are identical to those from the original package, we recommend
   that you check your inputs give the same results in both versions
   before publication.

   Please report all bugs in the EMBOSS version to the EMBOSS bug team,
   not to the original author.
