**RNAaliduplex**

The program reads two alignments of RNA sequences in CLUSTAL format and
predicts optimal and suboptimal binding sites, hybridization energies and the
corresponding structures. The calculation takes only inter-molecular base pairs
into account, for the general case use RNAcofold. The use of alignments allows
to focus on binding sites that are evolutionary conserved. Note, that the two
input alignments need to have an equal number of sequences and the same order,
i.e. the 1st sequence in file1 will be hybridized to the 1st in file2 etc.

The computed binding sites, energies, and structures are written to stdout, one
structure per line. Each line consist of: The structure in dot bracket format
with a &  separating the two strands. The range of the structure in the two
sequences in the format  "from,to : from,to"; the energy of duplex structure
in kcal/mol.
The format is especially useful for computing the hybrid structure between a
small probe sequence and a long target sequence.



-----

**Input format**

RNAaliduplex takes two alignment files generated with Clustal (*.aln).
