writeSimFastq: writeSimFastq: Create FASTQ files with simulated DNA k-mer...

In wokai/seqTools: Analysis of nucleotide, sequence and quality content on fastq files.

Description

Writes compressed FASTQ files where sequence sections contain concatenated k-mers which are uniformly distributed in the range of k-mers for given k.

Usage

writeSimFastq(k=6, nk=5, nSeq=10, filename="sim.fq.gz")

Arguments

k	numeric. Length of k-mer. Default value is 6.

nk	numeric. Number of k-mers in each FASTQ read. Default value is 5.

nSeq	numeric. Number of simulated reads in FASTQ-file. Default value is 10.

filename

character. Name of written (compressed) FASTQ file.

Details

The read headers are consequtive numbered. The phred quality values are equally set to 46 (='.') which represents a phred value of 13. This function is not designed for routine use. The random content FASTQ files can be used in order to measure the separation capabilities of hierarchical clustering mechanisms.

Value

None.
