Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web: http://bugzilla.bioperl.org/ Shawn Hoon Email shawnh@fugu-sg.org The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
