Rnall: RNA Local secondary structure prediction

Introduction

Rnall (RNA Local secondary structure prediction by Local symmetric mapping) predicts local RNA secondary structures for multiple sequences in the Fasta format or scans local secondary structure of a single genomic sequence in the Fasta format. Rnall scans the RNA sequence with a sliding window and extracts local secondary structure candidates based on dynamic programming. Then Rnall uses thermodynamic energy parameters to calculate the energies of local secondary structures. Rnall has various potential applications, such as local secondary structure prediction in RNA molecules, rho-independent terminator prediction, RNA motif prediction, and mi-RNA precursor prediction.

Rnall is written in C/C++, and is available for GNU/Linux at the present time.
