[Bioperl-l] how to prevent forced exit?

[Dave Messina]

Hi Ross,

Your code is incomplete and you didn't provide the output from running it,
so it's not easy to figure out where you're going wrong.

Try copying the example code directly from here


http://doc.bioperl.org/releases/bioperl-current/bioperl-live/Bio/DB/GenBank.html

and making sure that works first before modifying it.


More documentation and examples here:
