[Bioperl-l] [BULK] Re: can't parse blast file anymore

[Chris Fields]

What happens if you add the verbose flag?

my $search = new Bio::SearchIO (-verbose => 1,
                                -format => 'blast',
                                -file => $file);

Added thought : you might want to look at File::Find for stepping through
your files and performing a task on each one, such as parsing output.  It
changes into the working directory each time; you should be able to do
something like this:

use File::Find;
use Bio::SearchIO;
