**RNAdistance**


-----

**Input format**

RNAdistance requires one input file with the following structure:
1st line: can be a comment line like in Fasta, begins with '>'
2nd line: sequence
3rd line: first secondary structure in dot-bracket notation
4th line: second secondary structure in dot-bracket notation
...
nth line: another sequence
...

Several different RNA secondary structures can be specified. The input has a Fasta-like structure but with secondary structure information.


------

**Outputs**

* distance of the structures
* with the backtrack options it is possible to get alignment ouput
