Getting Taxonomic Blast Table Output Of 2.2.28 Using A Local Copy Of Nt

Hello!

I understand that taxonomic information for each blast HSP can now be output in the blast custom table format new in blast+ 2.2.28. My simple question is: how do I set up a local copy of NCBI's databases that is capable of outputting this information? Specifically, I'm interested in the nt and nr databases.

Thanks,

David
