[Bioperl-l] Bio::Tools::Blast;

[Fish Fish]

Hi,

  I am trying to pick out those blast results saying
"***** No hits found *****", among many other things.
But I can't get it work with Bio::Tools::Blast.  Can
somebody point out what is wrong in the following
code?  Also, it seems if the first of a multi blast
record is a "No hits found", then the 2nd record will
be skipped.

  Thanks in advance!
