Two Problems
We'll present two real-life problems and solve them with Perl. We will show you how Perl modules are used to fetch, munge and export data. We will show you that Perl is a practical and powerful tool.

lecture notes

1 | First Look at Perl | 0.1.0.1.1

Two real-life problems will be presented to show you how Perl is used. In Part I, the example will deal with analyzing C elegans data to address a biological question. We'll read sequence from a FASTA file and perform in-silico digests to analyze SAGE data. In Part II, we'll cover fetching, munging, and outputting - a common cycle. We'll show you how LWP::Simple and HTML::TreeBuilder can be used to fetch sample data from the web. Next, we'll examine how grep/map/sort can be used to manipulate hashes and arrays. We'll make some graphs using Graph::Undirected and GraphViz. Finally, we'll dump the munged data to a file and use grep/sort/uniq on it in bash.
