RNArobo is an RNA structural motif search tool. RNArobo can search sequence databases in FASTA format for a motif defined by a descriptor, which can specify primary and secondary structure constraints. The format of an RNArobo descriptor is an extension of the descriptor format used by RNABob (a search tool by S. Eddy), so that RNABob descriptors are compatible with RNArobo. Unlike RNABob, RNArobo enables you to allow nucleotide insertions in a structural element. RNArobo was developed in collaboration with the group of Andrej Luptak.
