The gto_fastq_quality_score_min analyses the minimal quality-scores of a FASTQ file.
For help type:
./gto_fastq_quality_score_min -h
In the following subsections, we explain the input and output paramters.
The gto_fastq_quality_score_min 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_min [options] [[--] args]
or: ./gto_fastq_quality_score_min [options]
It analyses the minimal 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_min -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

The output of the gto_fastq_quality_score_min program is a set of information related to the file read, considering the minimum 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
