Function

RNA melting

Description

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

It reads RNA sequences and calculates their specific heat in the temperature range t1 to t2, from the partition function by numeric differentiation. The result is output as a list of pairs of temperature in C and specific heat in Kcal/(Mol*K).

Algorithm

The program will continue to read new sequences until a line consisting of the single character "@" or an end of file condition is encountered.

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