BLAT is much faster than BLAST when doing many DNA-based searches in a
big genome like the human genome, but it will probably miss more
remote similarities than BLAST, as it has been mainly tuned for
mouse-human genomic distances. There are parameters that can be
adjusted to make it more sensitive but slower.
BLAT indexes the genome, which is fairly expensive, so is only a win
if you plan to do many searches.
