**RNApaln**

RNA alignment based on sequence base pairing propensities.

Uses string-alignment techniques to perform fast pairwise structural alignments of RNAs. Similar to RNApdist secondary structure is incorporated in an approximate manner by computing base pair probabilities, which are then reduced to a vector holding the probability that a base is paired upstream, downstream, or remains unpaired. Such pair propsensity vectors can then be compared using standard alignment algorithms. In contrast to RNApdist, RNApaln performs similarity (instead of distance) alignments, considers both sequence and structure information, and uses affine (rather than linear) gap costs. RNApaln can perform semi-local alignments by using free end gaps, a true local alignment mode is planned.

-----

**Input format**

RNApaln requires one input file
- Fasta file

------

**Outputs**

- output of alignment scores and alignments (if -B option is selected)
- dot plot matrices in postscript format bundled together in a tar file
