RNAstructure, Version 4.6

updated 5/6/2008

RNAstructure is a Windows program for the prediction and analysis of RNA secondary structure. It works with Windows ME, Windows NT 4, Windows 2000, Windows XP, and Windows Vista. (Note that with Windows Vista, you will need to install the older Windows help reader by following the instructions provided by Microsoft to use the online help. We are working to change this.) Version 4.6 includes a secondary structure prediction algorithm, a sequence editor, an integrated drawing tool, the OligoWalk program, OligoScreen, Dynalign, and a partition function calculator. RNAstructure uses the most current thermodynamic parameters from the Turner lab.

New for version 4.6 are stochastic sampling of secondary structures and the ability to constrain the prediction of the lowest free energy structure with SHAPE data.
