I believe the query is your sequence and the 'hits' are the HMMs (been  
a while since I used HMMER though).  In this case you don't want the  
hit start/end, you want $hsp->start('query')/$hsp->end('query') (or  
$hsp->query->start/$hsp->query->end, which should be the same thing).

See the HOWTO for SearchIO for more methods.


Some hit/HSP methods for HMMER aren't implemented, IIRC.  For an  
alternative faster approach you can try Sendu's hmmer_pull
