UNIX and Perl to the Rescue! (eBook, ePUB)

A Field Guide for the Life Sciences (and Other Data-rich Pursuits)

• Format: ePub

Produktbeschreibung

Your research has generated gigabytes of data and now you need to analyse it. You hate using spreadsheets but it is all you know, so what else can you do? This book will transform how you work with large and complex data sets, teaching you powerful programming tools for slicing and dicing data to suit your needs. Written in a fun and accessible style, this step-by-step guide will inspire and inform non-programmers about the essential aspects of Unix and Perl. It shows how, with just a little programming knowledge, you can write programs that could save you hours, or even days. No prior experience is required and new concepts are introduced using numerous code examples that you can try out for yourself. Going beyond the basics, the authors touch upon many broader topics that will help those new to programming, including debugging and how to write in a good programming style.

Rezensionen

'UNIX and Perl to the Rescue! is a book I highly recommend for all those students, post-docs, and academics who are scared of programming but can benefit immensely from the power of Unix and scripting languages. It's time to come out of your shell.' Dr M. D. Sharma, Genetics Society News
