The reduction and classification research on DNA fragment species attributes in meta genome

With the rapid development of meta genomics, sequenced meta genome number shot up as well as the DNA sequences expand. But the genera and species of most DNA sequences are unknown, so an important subject bioinformatics faced is how to research an attributes reduction and classification method for those huge meta genome DNA information. In this paper, we process attributes reduction and classification for those meta genome DNA fragments in different genera and the same genera but different species conditions respectively with the help of Rosetta experiment platform, which can get higher experimental resolution accuracy.
