Jen, Thank you very much for the information. They are very informative. I found the htgs and wgs databases information there. What does nt 28-Jan-2013 stand for? Meantime, if I am looking for virus containing database, I found wgs is one. Can anyone confirm or advice further if there is other options (database)? Thank you again!

Information about all can be found here: http://www.ncbi.nlm.nih.gov/genbank/ There are many uses, one example is covered in our Metagenomics publication: https://main.g2.bx.psu.edu/u/aun1/p/windshield-splatter Thanks!

There are four db options to blast against with - 1. htgs 28-Jan-2013 2. nt 28-Jan-2013 3. wgs 28-Jan-2013 4. phiX174 Is there any further information to guide which database would be appropriate to use? In addition, how to find the genome information contained in each database?
