sigma-align 1.1.3-1 (powerpc binary) in ubuntu karmic

 Sigma (“Simple greedy multiple alignment”) is an alignment program with a
 new algorithm and scoring scheme designed specifically for non-coding DNA
 sequence. It uses a strategy of seeking the best possible gapless local
 alignments, at each step making the best possible alignment consistent with
 existing alignments, and scores the significance of the alignment based on
 the lengths of the aligned fragments and a background model which may be
 supplied or estimated from an auxiliary file of intergenic DNA.
