Download instructions: The source code and binary executable for Linux, Mac and Windows can be downloaded from Github.
RCrane
Author: Kevin Keating
Description: RCrane allows for semi-automated building of RNA structure within Coot.
Current version: 1.1 (released September 26, 2012) View changelog

Download instructions: RCrane is included in Coot. Once Coot is launched, go to Extensions -> RCrane launch. RCrane will then be accessible through the newly-created RCrane menu. Coot downloads are available for Linux, Windows, and Mac. The source code for RCrane is available on GitHub.
Note: RCrane and Coot are also available through SBGrid.
AMIGOS III
Author: Morgan Shine & Chengxin Zhang
Description: AMIGOS III allows the user to perform interactive comparisons between RNA structures and to conduct database searches for specific RNA structures or substructures within the PyMOL molecular graphic system.
Download instructions: AMIGOS III is available as a PyMOL plugin at Github. An older version of AMIGOS II is available as a standalone Java applet at Github or through SBGrid.
Qnifft
Description: Qnifft utilizes the non-linear Poisson-Boltzmann (NLPB) equation to calculate the electrostatic potentials of nucleic acids.
Qnifft 1.4/2.2
Kim Sharp has developed an updated version of Qnifft that can be compiled for both Linux and SGI platforms. This program is available from his website.
Qnifft 1.2
SHEVEK
Author: Phillip S. Pang
Description: SHEVEK predicts long-range tertiary interactions within RNAs, between RNA-protein and protein-protein interactions from sequence alignments.
Reference: "Prediction of Functional Tertiary Interactions and Intermolecular Interfaces From Primary Sequence Data", PS Pang, E Jankowsky, LM Wadley and AM Pyle, J of Experimental Zoology (Mol Dev Evol) (2005), 000, 1-14.
Download instructions: SHEVEK is available on Github.
