**RNAplfold**

Computes local pair probabilities for base pairs with a maximal span of L. The probabilities are averaged over all windows of size L that contain the base pair. For a sequence of length n and a window size 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 stable RNA structures.


-----

**Input format**

RNAPplfold requires one input file

- Fasta file

------

**Outputs**

For each structure in the Fasta input a postscript image with dot-plot of the pairing probabilities is generated. Different output is generated with the "--ulength", "--print_onthefly" and "--opening_energies" flags.
The Dot Plot Matrices are stored in a Postscript file.
The other output is packed in a tar file.
