Overview of Solexa sequencinga.

aXM: M. fuliginosus from Sedon County; XO: other species bats from Sedon County; WM: M. fuliginosus from Wutao County; WO: other species bats from Wutao County; Datasize: the total length of contigs; Reads: the quantity of total reads after removal of contamination by host genome; Contigs: the numbers of contigs after overlapping; Rate: the reads ratio between the overlapped and the total; A. length: the average length of contigs; Eukaryotic, Bacterial and Virus-like: contigs relating to eukaryotes, bacteria and viruses; Unknown: sequences without a hit in the GenBank nonredundant database.
