[Bioperl-l] Can I get different Graphics::Panel colours fordifferent HSP frames within the same blast hit?

[Marcus Claesson]

Thanks for your answers guys!

That hack seems to do it. However, my program will be used by people
installing it themselves so I have to stick with the standard non-hacked
version of bioperl.

Cheers though,
Marcus
