**RNALalifold**

Calculates locally stable RNA secondary structure with a maximal base pair span. For a sequence of length n and a base pair span of L the algorithm uses only O(n+L*L) memory and O(n*L*L) CPU time. Thus it is practical to "scan" very large genomes for short RNA


-----

**Input format**

RNALalifold requires one input file
- Clustal file

------

**Outputs**

- energy of the consensus structures in the clustal file
- several possible postscript images bundled together in a tar file
