How can I combine my BLAST hits of the same species in my results file?

Question

[h.wilkinson]

I am performing a BLAST search using the 16S database but in my results every hit is individual. How can I combine hits of the same species together into one result? I am running blastn in the command line!

but in my results every hit is individual.

As in reads in your query are hitting common sequences in the database? Or is each query hitting multiple sequences in database?

How can I combine hits of the same species together into one result?

Answer may depend on the question above but if you choose to use one of the tab delimited output you could do some creative sorting of the results as a possibility.
