RAGTOP

 

Description:

The RNA-As-Graphs Topology (RAGTOP) software suite is developed in the lab of Prof. Tamar Schlick at New York University. The different features offered by this software include representing RNA secondary structure as three-dimensional tree graphs and sampling different graph topologies [3, 4]; fragment assembly for RNA graphs (F-RAG) to generate 3D atomic models of RNA for graphs [5], and design of sequences to fold onto RNA-like tree graph topologies [6].

Copyright Statement:

The RAGTOP software suite was developed in the lab of Prof. Tamar Schlick at New York University. The package is provided for use in research purposes only; for other applications please contact Prof. Tamar Schlick. We require everyone who publishes or presents results from RAGTOP to please cite our program, names of individual components, and associated original publications, as below:

Citation Requirements:

Please cite the papers below when using RAGTOP. Papers 1 and 2 are for RAGTOP's JunctionExplorer component to predict coaxial stacking and family for 3-way and 4-way junctions; papers 3 and 4 are for RAGTOP's Monte Carlo/Simulated Annealing component to sample 3D tree graph topologies; and papers 5 and 6 are for RAGTOP's F-RAG component to generate atomic models for RNA 3D structure prediction and design of RNA-like topologies.
