FASTQ file. 1st line always starts with the symbol ‘@’ followed by the sequence identifier. 2nd line contains the sequence. 3rd line starts with the symbol ‘+’ symbol which is optionally followed by the same sequence identifier and any description. It indicates the end of the sequence and the beginning of the quality score string. 4th line contains the quality score (QS) in ASCII format. The current example shows an Illumina representation.
