Hi Gregory,

it's simple enough to give bwa a try:

bwa index -a bwtsw genome.fa;
bwa aln -l 19 genome.fa primers.fa > temp.sai
bwa samse genome.fa temp.sai primers.fa

Has actually anyone tried BWA to map primers? I get a lot more results
than with blat and blast and have to compare their results now. My
problem might be different from Gregory's though as I have ~700k
primers to map onto ~60 genomes...

PS: Having read the bwa documentation, it seems that the long-sequence
alignment mode bwasw in combination with sam2psl.pl might be a nice
drop-in replacement for blat... ?

cheers
Max
