[Bioperl-l] problem with Graphics

[Sean O'Brien]

Hi,

I have been trying to get BioPerl to output png's, but I seem to be getting 
invalid png files.  I have a fresh install of libgd, version 2.0.15 and my GD 
version is 2.07.  I installed Bundle::BioPerl, and after having no luck, I 
installed BioPerl version 1.2.2 from the sources in 
current_core_stable.tar.gz.  When I run 'make test' I get an ok for 
BioGraphics.  Also, when I run the first script described in the Bio Graphics 
tutorial, it runs with no errors and outputs some data which appears as 
though it could be an image.  However, the file seems to be of an invalid png 
format because it cannot be opened by display, galeon or the GIMP.  This is 
pretty frustrating because everything apears to be installing/running fine, 
but then the image is somehow corrupted.  What might I have done wrong/ need 
to do to make this work.  Thanks.
