WebThe quality score of a base, also known as a Phred or Q score, is an integer value representing the estimated probability of an error, i.e. that the base is incorrect. If P is the error probability, then: P = 10-Q/10 Q = -10 log10(P) Q scores are often represented as ASCII characters. WebThe FASTQ file format is the defacto file format for sequence reads generated from next-generation sequencing technologies. This file format evolved from FASTA in that it contains sequence data, but also contains …
