A quality value Q is an integer mapping of p (i.e., the probability that the corresponding base call is incorrect). Two different equations have been in use. The first is the standard Sanger variant to assess reliability of a base call, otherwise known as Phred quality score: The Solexa pipeline (i.e., the software delivered with the Illumina Genome Anal… WebRead a FASTQ file into an array of structures: % Read the contents of a FASTQ-formatted file into % an array of structures reads = fastqread ('SRR005164_1_50.fastq') reads = 1x50 struct array with fields: Header Sequence Quality Read a FASTQ file into three separate variables:

FASTA and FASTQ formats are both file formats that contain sequencing reads while SAM files are these reads aligned to a reference sequence. In other words, FASTA and FASTQ are the "raw data" of sequencing while SAM is the product of aligning the sequencing reads to a refseq.
