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 all LSS with sizes no longer than a window size using dynamic programming. Rnall has various potential applications, such as local secondary structure prediction in RNA molecules and RNA motif prediction (such as rho-independent/intrinsic terminator, riboswitch, siRNA, and viral RNA motifs).
Rnall is written in C/C++, and is available for both GNU/Linux and windows at the present time.
Rnall was written by Xiu-Feng (Henry) Wan. The software Rnall is freely available for academic or non-commercial purpose at http://sysbio.cvm.msstate.edu/Rnall.
Current versions of Rnall are available for both Windows and GNU/Linux system. If you need the versions for different operating systems, please contact Xiu-Feng (Henry) Wan by email@example.com.
Version 2.0 was jointly developed by Wan, X.-F., Lin, G., and Xu, D. Rnall scans the RNA sequence with a sliding window and extracts all LSS with sizes no longer than a window size using dynamic programming within a single run. Rnall has a time complexity of O(W3L) in the worse case, where W is the window size (typically a small constant less than 100 nt) and L is the sequence length. In practice, we observed an average computing time in O(W2L).
Version 1.1 was jointly developed by Wan, X.-F. and Xu, D. Version 1.1 is a general RNA local secondary structure prediction tool as well as a tool for intrinsic terminator (rho-independent terminator) prediction. The user manual 1.1 explains the installing and running commands for Rnall 1.1.
The user manual 2.0 explains the installing and running commands for Rnall 2.0.
