The Foldalign web server for pairwise structural RNA alignment and mutual motif search

Abstract

Foldalign is a Sankoff-based algorithm for making structural alignments of RNA sequences. Here, we present a web server for making pairwise alignments between two RNA sequences, using the recently updated version of foldalign. The server can be used to scan two sequences for a common structural RNA motif of limited size, or the entire sequences can be aligned locally or globally. The web server offers a graphical interface, which makes it simple to make alignments and manually browse the results. The web server can be accessed at http://foldalign.kvl.dk. © 2005 Oxford University Press.
