metaMetaCV: a composition-based algorithm to classify metagenomic reads and function - SAMPLE SIMULATED DATA avail for download

We have developed a tool MetaCV to classify the very short metagenomic reads into specific taxonomic and functional groups.
Comparing to previous methods, there are some advantages:
1, Even faster and more accuracy than before methods, even for ~500 Gb Meta-Hit data, only take 2 days to classify and characterize this metagenomic data. 
2, Except obtaining taxonomic information, it also provided functional enrichment of identified microorganisms.
3, Easy to use, the tool can download from 
http://metacv.sourceforge.net/ 
there are also some sample data for simulation.
