Plot summary statistics of a BioReadQualityStatistics object
H = plotSummary(QSObj)
plotSummary(QSObj) plots summary statistics of the BioReadQualityStatistics object QSObj that contains six plots about the average quality score for each base position, average quality score distribution, read count percentage for each base position, percentage of GC content for each base position, GC content distribution, and nucleotide distribution.
Create a BioReadQualityStatistics object from a FASTQ file using only the first 40 characters of each read with a minimum average quality score of 5.
QSObj = BioReadQualityStatistics('SRR005164_1_50.fastq','FilterLength',40,... 'QualityScoreThreshold',5);
Plot summary statistics of QSObj.
