Objectives and Topics
This guide aims to provide a practical introduction to using PERL and BioPERL for bioinformatics tasks. It focuses on equipping researchers and students with the necessary programming skills to extract, manipulate, and analyze biological sequence data through a series of concrete, executable code examples.
- Fundamental PERL syntax, data types, and control structures for bioinformatics.
- Methods for processing and analyzing biological sequences (e.g., GC content, translation, reverse complement).
- Effective use of CPAN modules to extend functionality.
- Practical application of BioPERL for sequence analysis, parsing BLAST results, and alignment manipulation.
Excerpt from the Book
Program 1: Concatenation
Variables are denoted with symbol $. Concatenation is the process of joining two or more strings (in variables) into a common string. In the present program, the two strings (or set of characters) have been combined into single string through various processes. Joining of strings can be also done using dot (.) operator.
Program
$DNA1 = 'ATGTACACTAC';
$DNA2 = 'GATCATGT';
$DNA3 = "$DNA1$DNA2";
print "first string: $DNA1 \n";
print "second string: $DNA2 \n";
print "concatenation of two strings (version 1):\n\n";
print "$DNA3\n\n";
$DNA3 = $DNA1 . $DNA2;
print "concatenation of two strings (version 2):\n\n";
print "$DNA3\n\n";
print "concatenation of two strings (version 3):\n\n";
print $DNA1, $DNA2, "\n";
exit;
