Pairwise RNA Structure Comparison with Stochastic Context-Free Grammars
نویسندگان
چکیده
Pairwise stochastic context-free grammars ("Pair SCFGs") are powerful tools for finding conserved RNA structures, but unconstrained alignment to Pair SCFGs is prohibitively expensive. We develop versions of the Pair SCFG dynamic programming algorithms that can be conditioned on precomputed structures, significantly reducing the time complexity of alignment. We have implemented these algorithms for general Pair SCFGs in software that is freely available under the GNU Public License.

Pairwise RNA Pseudoknotted Structure Prediction Based on Stochastic Grammar
RNA secondary structure prediction is one of the major topics in bioinformatics. A prediction method based on a parsing algorithm for formal grammars is a promising approach. Also, it is expected that comparative sequence analysis achieves higher accuracy than the one using a single sequence since the former approach can use evolutionary information that homologous RNAs are likely to conserve a...
متن کاملIntroduction to stochastic context free grammars.
Stochastic context free grammars are a formalism which plays a prominent role in RNA secondary structure analysis. This chapter provides the theoretical background on stochastic context free grammars. We recall the general definitions and study the basic properties, virtues, and shortcomings of stochastic context free grammars. We then introduce two ways in which they are used in RNA secondary ...
متن کاملStochastic Context-Free Grammars and RNA Secondary Structure Prediction
This thesis focus on the prediction of RNA secondary structure using stochastic context-free grammars (SCFG). The RNA secondary structure prediction problem consists of predicting a 2-dimensional structure from a 1-dimensional nucleotide sequence. The theory behind SCFG is explained and an overview of the research literature on various methods in the field of secondary structure prediction is g...

متن کاملSmall Subunit Ribosomal RNA Modeling Using Stochastic Context-Free Grammars
We introduce a model based on stochastic context-free grammars (SCFGs) that can construct small subunit ribosomal RNA (SSU rRNA) multiple alignments. The method takes into account both primary sequence and secondary structure basepairing interactions. We show that this method produces multiple alignments of quality close to hand edited ones and outperforms several other methods. We also introdu...
