摘要：

A novel bioinformatics features based DNA Sequence data compression algorithm of BioLZMA is proposed in this paper. In BioLZMA, the DNA sequence data is sliced and reformed into 4 clusters according with biological meanings: the coding sequence cluster, the intron cluster, the RNA cluster and the residual cluster. By employing pointed compression strategies in data pre-processing, the clusters are compressed separately with LZMA algorithm. Experimental results demonstrated the better performance of BioLZMA than original DNA compression algorithms on benchmark sequences. Especially on long DNA sequence with significant bioinformatics features, BioLZMA algorithm can achieve higher compression ratio with little computation time.
