           Summary: Bio::Tools::Primer3.pm bug in returned number of primers
           Product: Bioperl
           Version: main-trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core Components
        AssignedTo: bioperl-guts-l at bioperl.org
        ReportedBy: nathanhaigh at ukonline.co.uk


This bug is related to the issues brought up by George:
http://bioperl.org/pipermail/bioperl-l/2005-June/019092.html

If no primers are found Bio::Tools::Primer3::number_of_results returns 1.
So if you use $results->number_of_results to check that you have some primers
returned and then do a $results->next_primer you get an exception "No left
primer sequence"

This can be fixed by setting $maxlocation=-1 on line 392. I will submit the
change to cvs.

Nathan
