NAME Data::Random::Nucleotides - Generate random nucleotide strings. VERSION version 0.1 SYNOPSIS use Data::Random::Nucleotides qw/:all/; # Generate a string of 200 random A/C/G/T characters. $nucs = rand_nuc ( size => 200 ); # Generate a string of random A/C/G/T between 20 and 500 characters. $nucs = rand_nuc ( min => 20, max => 500 ); # Generate a string of 30 random A/C/G/T/N characters. $nucs = rand_nuc ( size => 30, N=>1 ); # Generate a multi-lined string of 500 random A/C/G/T/N characters. # The 500 characters will be split into lines of 70 characters each. $nucs = rand_wrapped_nuc ( size => 500 ); # Generate a string containing a single FASTA-like sequence text. $fasta = rand_fasta ( size => 200 ) ; DESCRIPTION This module is a thin wrapper around Data::Random, providing utility functions to generate nucleotide sequence strings and FASTA-looking strings. nucleotide strings contain only A/C/G/T (and possibly N) characters. FASTA strings are multi-lined nucleotide strings, with the first line containing a sequence id (see http://en.wikipedia.org/wiki/FASTA_format) . METHODS rand_nuc() Returns a string of random nucleotides. See `rand_set' in Data::Random for possible parameters (e.g. `size', `min', `max'). If `N' is set, N will be a possible nucleoide. Otherwise - only A/C/G/T will be returned. rand_wrapped_nuc() Returns a multi-lined string of random nucleotides. See `rand_nuc' for all possible parameters. The returned string will be broken into lines of 70 characeters each. rand_fasta() Returns a random FASTA string. First line begins with a `>' prefix, and a random sequence ID (alphanumeric). The rest of the lines are random nucleotide strings, wrapped at 70 characters. AUTHOR Assaf Gordon, `' TODO Finer control over nucleotide composition (currently: completely random) Generate FASTQ files Support lower-case nucleotides generate amino-acid codes BUGS Please report any bugs or feature requests to https://github.com/agordon/Data-Random-Nucleotides/issues SEE ALSO BioPerl provides similar functionality http://www.bioperl.org/wiki/Random_sequence_generation, but requires installing the BioPerl module.
