C.4. What Is BioPerl?

BioPerl is an open source (essentially free) toolkit of over 500 Perl modules that enable scripts to analyze large quatities of data for Web-based systems. "Bioperl provides reusable Perl modules that facilitate writing Perl scripts for sequence manipulation, accessing of databases using a range of data formats, and execution and parsing of the results of various molecular biology programs including Blast, clustalw, TCoffee, genscan, ESTscan, and HMMER." BioPerl also supports accessing remote databases as well as creating indices for accessing local databases. BioPerl lets you build programs that can analyze huge quantities of sequence data. It does require familiarity with object-oriented Perl and does not provide complete ready-made programs; it provides a set of tools to simplify common bioinformatic tasks. BioPerl is always being developed and maintained by a large number of programmers.

For complete installation instructions, see the BioPerl home page at www.bioperl.org. The easiest way to install BioPerl is to use the PPM manager provided by ActiveState for all major operating systems or by upacking the tar file and entering the following commands:

   >gunzip bioperl-1.2.tar.gz
>tar xvf bioperl-1.2.tar
>cd bioperl-1.2

Now issue the make commands:

>perl Makefile.PL
>make
>make test

For downloads and information, go to the BioPerl Web site shown in Figure C.2

Example C.4.

(Perl Script using bioperl modules from the bioperl Web site)
use Bio::Seq;
use Bio::SeqIO;

# create a sequence object of some DNA
my $seq = Bio::Seq->new(-id => 'testseq', -seq => 'CATGTAGATAG'
);

# print out some details about it
print "seq is ", $seq->length, " bases long\n";
print "reversed complement seq is ", $seq->revcom->seq, "\n";

# write it to a file in Fasta format
my $out = Bio::SeqIO->new(-file => '>testseq.fsa', -format => '
Fasta');
$out->write_seq($seq);

(Output)
seq is 11 bases long
reversed complement seq is CTATCTACATG

$ more testseq.fsa   <-- The FASTA file
>testseq
CATGTAGATAG

http://www.bioperl.org/wiki/Bptutorial#Quick_getting_started_scripts

BioPerl comes with a set of production-quality scripts that are kept in the scripts/ directory. You can install these scripts by answering the questions on make install. The default location directory is /usr/bin. Installation will copy the scripts to the specified directory, change the PLS suffix to pl, and prepend bp_ to all the script names if they aren't so named already.
