Hi All,

Suppose, I have a fa file with 1000 DNA fragement (100bp each) from difference species. Now I want to judge the species origin of each fragment, How should I do? 

I tried blast. the blast would give me lots of result for each fragment. but I have 1000 fragment? Can I set blast to show me one result for each fragment? and output these result for 1000 fragment simultaneously?

 Max matches in a query range =1 ? 

 Max target sequences =1 ? 

 

Thanks.

Did you try to blast the sequences?
