The rboAnalyzer is a tool for analysis of BLAST output when the query sequence is an RNA. It is designed to work with ncRNAs and other RNA sequences that have functional structure.

The rboAnalyzer process requested high-scoring pairs (HSPs) in BLAST output and extends the subject sequence matches to their full length. Then estimates homology of the full-length matches. And finally predicts secondary structures of the full-length matches by multiple methods.

The rboAnalyzer was originally developed as command-line application which is accessible from github.com/cas-bioinf/rboAnalyzer.

Used rboAnalyzer pipeline backend version is 0.1.5a1.

This is a webserver frontend to rboAnalyzer which can analyze BLAST outputs from NCBI BLAST webserver.

The webserver is able to process blastn searches in nucleotide databases with indexed by sequences identifiers (accessions) referring to GenBank or RefSeq accessions format (ncbi.nlm.nih.gov/Sequin/acc.html), provided that the accessions are available.
