    <help><![CDATA[ **LocARNA -- Pairwise alignment of RNAs**

Pairwise RNA alignment tools of the LocARNA suite (locarna,
sparse). These tools perform variants of simultaneous RNA folding and
alignment. They can be adapted to specific needs by a broad range of
parameters:

* *scoring* of the alignment, e.g. influencing the cost of
  insertions/deletions and the weight of sequence vs. structure
  similarity.

* *RNA folding*, which control the secondary RNA structure prediciton.

* *heuristics*, which trade alignment accuracy vs. computation
  speed. The huge complexity of simultaneous alignment and folding
  generally requires some heuristics for reasonable computation times.
  Some alignment instances and alignment modes will require relaxation
  of the default heuristics; in particular, local, constrained, and free end gap
  alignment, will often require turning off the "maximal difference for
  alignment traces" heuristic.
  
* *constraints*, which can be applied to include prior knowledge to
  improve the quality of results and/or speed of computation.

**Input.**

Input consists of two sequences or alignments, which are specified in
fasta, clustal, stockholm, or LocARNA pp format.

Optionally, one can specify structure and anchor constraints in these
input files.

**Output.**

The final pairwise alignment is reported in standard and/or variants of the
clustal and stockholm format, as well as LocARNA's own pp format.
