Learning Perl

Objectives

Read and understand chapters 1-13 in Learning Perl.
- Perl quick reference

Know how to use standard modules. For example, File::Basename and Getopt::Long are some of the most useful ones.
Know how to use BioPerl. This may not be necessary for simple scripting but is extremely useful if you need to work on sequence data (e.g., BLAST output).
See the big picture: using perl scripts to solve real-world research problem.
- Example: download a list of GenBank records (Batch Download Entrez)
Know how to read other people's scripts. See scripts in the perl example page.
- Can you describe, conceptually, how each script solves a particular problem?
- Do you understand how they work? Can you explain every line in a script?
- If someone accidentally (or purposely) introduces a bug in a script, can you fix it?
