[Bioperl-l] Problem rendering a BLAST result

[Kevin Brown]

Would help if we can see your code as line 68 of yeah.pl is the final
line of the script you linked.

It is trying to set the bgcolor based on a value that it thinks should
be held in the Bio::SeqFeature::Generic object as a tag, but no such tag
exists.
