Re: Bioperl Graphics question

[monarch]

It would appear, for whatever reason, the -label argument isn't being interpreted as being true.

Yet you seem to set it just as the tutorial example showed.

I could not find the Bio::Graphics module in CPAN, so I couldn't look up the documentation (occasionally tutorial code examples are wrong and it helps to track down the documentation directly).

You may be able to find the module in something like:

  /usr/lib/perl5/site_perl

and running

  find . |grep Bio |grep Graphics

Alternatively if you're on windows, open explorer, go to your Perl installation directory (C:\Perl\?) and then from the explorer window right-click on the directory name, select search, and type in Graphics.pm.

Bio:::Graphics is a namespace for a set of modules used for drawing images common to Bioinformatics. On my machine it's located in the directory /usr/local/lib/perl5/site_perl/5.8.6/Bio/Graphics.

You could poke around there (or somewhere similar) if you'd like a peek at the source code. Probably the most reasonable thing to do would be to e-mail the Bioperl mailing list (there's a link off the website) and tell them your problem. Also, you might try some of the later examples in the tutorial and see if those work for you.

I ran the example using both sets of code and got the image with labels on it, so I don't know what the problem would be. What OS and Bioperl version are you using? Bioperl makes heavy use of the GD Perl package, what version of GD are you using?
