Bioperl What’S Bioperl?
Bioperl What’s Bioperl? Bioperl is not a new language It is a collection of Perl modules that facilitate the development of Perl scripts for bioinformatics applications. Bioperl and perl Bioperl Modules Perl Modules Perls script input Perl Interpreter output Bioperl and Perl Why bioperl for bioinformatics? Perl is good at file manipulation and text processing, which make up a large part of the routine tasks in bioinformatics. Perl language, documentation and many Perl packages are freely available. Perl is easy to get started in, to write small and medium-sized programs. Where to get help Type perldoc <modulename> in terminal Search for particular module in https://metacpan.org Bioperl Document Object-oriented and Process-oriented programming Process-oriented: Yuan Hao eats chicken Name object: $name Action method: eat Food object: $food Object-oriented: $name->eat($food) Modularize the program Platform and Related Software Required Perl 5.6.1 or higher Version 5.8 or higher is highly recommended make for Mac OS X, this requires installing the Xcode Developer Tools Installation On Linux or Max OS X Install from cpanminus: perlbrew install-cpanm cpanm Bio::Perl Install from source code: git clone https://github.com/bioperl/bioperl-live.git cd bioperl-live perl Build.PL ./Build test (optional) ./Build install Installation On Windows Install MinGW (MinGW is incorporated in Strawberry Perl, but must it be installed through PPM for ActivePerl) : ppm install MinGW Install Module::Build, Test::Harness and Test::Most through CPAN: Type cpan to enter the CPAN shell.

EGTDC Perl Course 2004
EGTDC Perl Course 2004 Making use of CPAN modules Perl on other platforms Tim Booth : [email protected] Environmental Genomics Thematic Programme Data Centre http://envgen.nox.ac.uk CPAN Recap • "Comprehensive Perl Archive Network". • Holds virtually every Perl module, among other things. • Access via the web (http) and by the CPAN shell. – search.cpan.org is probably your first point of call. • Most modules are standardised to make them easy to use right away: – Documentation in ©perldoc© format. – Standard installation procedure – Self-testing Environmental Genomics Thematic Programme Data Centre http://envgen.nox.ac.uk CPAN and modules • CPAN contains around 2860 modules - bits of code that can be plugged into your scripts. Some are small, some complex. • Need to interface with a database? Use the DBI/DBD modules. • Need to make webpages with Perl? Use the CGI module. • Need to make a graphical interface? Use the Tk module. • Need to do bioinformatics? Use the BioPerl modules! • To use an installed module you "use module_name;" in the same way as you "use strict;" • Modules can be installed in 2 ways – Manually, from source – From CPAN, using the CPAN shell. Environmental Genomics Thematic Programme Data Centre http://envgen.nox.ac.uk Installing modules from source • On Bio-Linux, log in as manager to install modules system-wide • Modules are distributed as .tar.gz files. • Download the module to the manager©s home directory. • if you are missing components required for the module to work you will be told at the 2nd step below. • Always check README or INSTALL files before installing. -

Advancing Perl Supporting Community
Advancing Perl Supporting Community 2012 Year End Report Board of Directors Nathan Torkington Chairman Karen Pauley President Jim Brandt Secretary Dan Wright Treasurer Kurt DeMaagd Curtis “Ovid” Poe Allison Randal Kevin Lenzo Director Emeritus Committee Chairs Alberto Simões Grants Heath Bair Conferences Mark Keating Marketing Ya’akov Sloman Community Advocacy Karen Pauley Steering The Perl Foundation 340 S Lemon Ave #6055 Walnut, CA 91789 The Perl Foundation is a business alias for The Yet Another Society, a 501-c-3 charitable organization, incorporated in the state of Michigan. A Look Inside: TPF Inside: A Look President’s Message This has been a great year for The Perl Foundation. Thanks to the generosity of our donors and corporate partners, the commitment of our volunteers, and the vitality and energy of our community, we have been able to continue in our mission to advance the Perl programming language. As you know, TPF depends on donations, both of time and money, to operate. These donations have made it possible for us to provide financial support to key developers of Perl 5 and Perl 6, to continue our efforts in protecting our trademark, and to support many community programs. One of the pillars of Perl is its community. We recently launched an initiative, the Community Advocacy Committee, targeting the growth and health of the Perl community. With the help of this committee we plan to not only improve communication within our own community but to expand our links with other F/OSS communities. This year has been one pointing to a great future for Perl and those who use it. -

Compiling Your Own Perl
APPENDIX A Compiling Your Own Perl Compiling Perl on a Unix-like system is simple. First, obtain the source for Perl from CPAN (dppl6++_l]j*lanh*knc+on_+NA=@IA*dpih). Then input the following sequence of commands: p]nvtrblanh)1*4*4*p]n*cv _`lanh)1*4*4 od?kjbecqna)`ao i]ga i]gapaop oq`ki]gaejop]hh On most Unix systems, this code will result in your lanh being installed into the +qon+ hk_]h+ directory tree. If you want it installed elsewhere—for example, in the local directory in your home directory—then replace od?kjbecqna)`a with the following: od?kjbecqna)`ao)@lnabet9z+hk_]h+ which should enable you to install Perl on your computer without root access. Note that the )`ao flag uses all the default options for compiling Perl. If you know that you want nonstandard configuration, just use the flag )`a instead to be prompted for your requirements. Be aware that the source for Perl 5.10.0 requires a patch to work properly with Catalyst. This is fixed in subsequent versions of Perl 5.10. If you need to test code guaranteed to run on a wide range of systems, you should con- sider using Perl version 5.8.7. Perl versions greater than 5.8.7 contain features that were not available in earlier versions of Perl, so Perl 5.8.7 is feature complete for all versions of Perl that Catalyst will run on (version 5.8.1 and later). Put another way, versions 5.8.8 and later have new features that you can’t rely on in earlier releases.
