pmmultiare two programs to perfrom pairwise and progressive multiple alignments of RNA sequences.
pmcompis a variant of Sankoff's algorithm for simultaneous folding and alignment, which takes as input pre-computed base pair probability matrices from McCaskill's algorithm as produced by RNAfold -p. Thus the method can also be viewed as way to compare base pair probability matrices.
pmmultiis a simple wrapper program that does progressive multiple alignments by repeatedly calling
At the moment we offer prototypes for the programs written in Perl. A faster C version will hopefully follow soon.

Run pmcomp.pl --man or pmmulti.pl --man to view the respective man pages.
