Comparative methods

The single sequence methods mentioned above have a difficult job detecting a small sample of reasonable secondary structures from a large space of possible structures. A good way to reduce the size of the space is to use evolutionary approaches. Structures that have been conserved by evolution are far more likely to be the functional form. The methods below use this approach.

RNA-ensign This approach applies an efficient global sampling algorithm to examine the mutational landscape under structural and thermodynamical constraints. The authors show that the global sampling approach is more robust, succeeds more often and generates more thermodynamically stable sequences than local approaches do. Source Code [170]
IncaRNAtion Successor of RNA-ensign that is able to specifically design sequences with a specified GC content using a GC-weighted Boltzmann ensemble and stochastic backtracking Source Code [171]
DSS-Opt The Dynamics in Sequence Space Optimization (DSS-Opt) approach uses Newtonian dynamics in the sequence space in combination with a negative design term and simulated annealing to optimize a sequence such that it folds into the desired secondary structure. Source Code [172]
MODENA This approach interprets RNA inverse folding as a multi-objective optimization problem and solves it using a genetic algorithm. In its extended version MODENA is able to design pseudoknotted RNA structures with the aid of IPknot. Source Code [173][174]
ERD Evolutionary RNA Design (ERD) can be used to design RNA sequences that fold into a given target structure. Any RNA secondary structure contains different structural components, each having a different length. Therefore, in the first step, the RNA sub-sequences (pools) corresponding to different components with different lengths are reconstructed. Using these pools, ERD reconstructs an initial RNA sequence which is compatible with the given target structure. Then ERD uses an evolutionary algorithm to improve the quality of the sub-sequences corresponding to the components. The major contributions of ERD are utilizing the natural RNA sequences, a different method for evaluating the sequences in each population, and a different hierarchical decomposition of the target structure into smaller sub-structures.

Dual state design
switch.pl The ViennaRNA package provides a Perl script to design RNA sequences that are able to adopt two states. For instance RNA thermometer, which change their structural state depending on the environmental temperature, have been successfully designed using this program. Man Page Source Code [176]
RiboMaker RiboMaker is intended to design small RNAs (sRNA) and their target mRNA's 5'UTR. The sRNA is designed to activate or repress protein expression of the mRNA. It is also possible to design just one of the two RNA components provided the other sequence is fixed. Web Server Source Code [177]
Multi state design
RNAdesign The underlying algorithm of RNAdesign is based on a combination of graph coloring and heuristic local optimization to find sequences that are able to adapt multiple prescribed conformations. In addition the software is also able make use of RNAcofold to design interacting RNA sequence pairs. Source Code [178]
Frnakenstein Frnakenstein applies a genetic algorithm to solve the inverse RNA folding problem. Source Code [179]
ARDesigner The Allosteric RNA Designer (ARDesigner) is a web-based tool that solves the inverse folding problem by incorporating mutational robustness. Beside a local search the software has been equipped with a simulated annealing approach to effectively search for good solutions. The tool has been used to design RNA thermometer. [Note 1] [180]
