Book Description

Perl is a versatile, powerful programming language used in a variety of disciplines, ranging from system administration to web programming to database manipulation. One slogan of Perl is that it makes easy things easy and hard things possible. “Intermediate Perl” is about making the leap from the easy things to the hard ones.Originally released in 2003 as “Learning Perl Objects, References, and Modules” and revised and updated for Perl 5.8, this book offers a gentle but thorough introduction to intermediate programming in Perl. Written by the authors of the best-selling “Learning Perl,” it picks up where that book left off. Topics include:

• Packages and namespaces
• References and scoping
• Manipulating complex data structures
• Object-oriented programming
• Writing and using modules
• Testing Perl code
• Contributing to CPAN

Following the successful format of “Learning Perl,” we designed each chapter in the book to be small enough to be read in just an hour or two, ending with a series of exercises to help you practice what you’ve learned. To use the book, you just need to be familiar with the material in “Learning Perl” and have ambition to go further. Download Now »

Book Description

This book is devoted to the fundamentals of text mining using Perl, an open-source programming tool that is freely available via the Internet (www.perl.org). It covers mining ideas from several perspectives–statistics, data mining, linguistics, and information retrieval–and provides readers with the means to successfully complete text mining tasks on their own.

The book begins with an introduction to regular expressions, a text pattern methodology, and quantitative text summaries, all of which are fundamental tools of analyzing text. Then, it builds upon this foundation to explore:

• Probability and texts, including the bag-of-words model
• Information retrieval techniques such as the TF-IDF similarity measure
• Concordance lines and corpus linguistics
• Multivariate techniques such as correlation, principal components analysis, and clustering
• Perl modules, German, and permutation tests

Each chapter is devoted to a single key topic, and the author carefully and thoughtfully introduces mathematical concepts as they arise, allowing readers to learn as they go without having to refer to additional books. The inclusion of numerous exercises and worked-out examples further complements the book’s student-friendly format. Download Now »

Book Description

Working on the assumption that the reader has no formal training in programming, Perl Programming for Biologists demonstrates how Perl is used to solve biological problems. Each chapter opens with a set of learning objectives, provides numerous review questions and self-study exercises, and concludes with a bulleted summary of key points. The author incorporates numerous real-life examples throughout the text. Upon completing the book, readers are able to quickly perform such tasks as correcting recurring errors in spreadsheets, scanning a Fasta sequence for every occurrence of an EcoRI site, adapting other writers’ scripts to one’s own purposes, and most important, writing reusable and maintainable scripts that spare the rote repetition of code.

From the Back Cover
With a loose structure that allows for fast and easy coding, the Perl programming language is the most widely used scripting language in bioinformatics. Working on the assumption that the reader has never had any formal training in programming, and using examples geared toward real problems faced by biologists, Perl Programming for Biologists serves as an accessible, introductory reference for teaching Perl programming.

Curtis Jamison’s innovative text introduces basi c elements of computer science and software engineering in an abbreviated format, building toward a bioinformatics users’s guide for Perl. Each chapter opens with a set of learning objectives, provides numerous review questions and self-study exercises, and concludes with a bulleted summary of key points. Jamison incorporates numerous real-life examples throughout to illustrate how Perl is used to solve biological problems, offering valuable code fragments that the current practitioner can recycle into his or her own program. Divided into sections on basic, intermediate, and advanced-level Perl, the book includes chapters on: Download Now »

Book Description

Sams Teach Yourself Perl in 21 Days covers the basics of Perl in the first few chapters, and then moves on to practical issues of Perl and in-depth discussions of more advanced topics. Later chapters also delve into software engineering topics, with discussions of modular code and object-oriented programming. CGI is covered in one chapter, but it is not the focus on the book. The book relies heavily on longer working examples and code, as opposed to small snippets and code fragments, and each chapter includes two to three smaller complete examples and one major one that illustrates most of the concepts for that chapter and builds on the chapters before it. Written by Laura Lemay, this is her third major book after Sams Teach Yourself Web Publishing with HTML in 21 Days and Sams Teach Yourself Java in 21 Days.
