Program gto_fastq_quality_score_max

The gto_fastq_quality_score_max analyses the maximal quality-scores of a FASTQ file.

For help type:

./gto_fastq_quality_score_max -h


In the following subsections, we explain the input and output paramters.

Input parameters

The gto_fastq_quality_score_max program needs two streams for the computation, namely the input and output standard. The input stream is a FASTQ file.

The attribution is given according to:

Usage: ./gto_fastq_quality_score_max [options] [[--] args]
or: ./gto_fastq_quality_score_max [options]

It analyses the maximal quality-scores of a FASTQ file.

-h, --help show this help message and exit

Basic options
< input.fastq Input FASTQ file format (stdin)
> output Output read information (stdout)

Optional
-m, --max= The maximum window length (default 40)

Example: ./gto_fastq_quality_score_max -m < input.fastq > output


An example of such an input file is:

@111 071112_SLXA-EAS1_s_7:5:1:817:345 length=72 1

Output

The output of the gto_fastq_quality_score_max program is a set of information related to the file read, considering the maximal quality scores.

Using the input above with the max window value as 30, an output example for this is the following:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
