Function

RNA eval with cofold

Description

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

The original program has additional inputs and produces different outputs, depending on the options selected. In the EMBASSY implementation it is split into vrnaeval and vrnaevalpair

Algorithm

See the original documentation for the Vienna RNA package http://www.tbi.univie.ac.at/~ivo/RNA/

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.
