data Fastq

A FASTQ file normally uses four lines per sequence.

• Line 1 begins with a '@' character and is followed by a sequence identifier and an optional description (like a FASTA title line).
• Line 2 is the raw sequence letters.
• Line 3 begins with a + character and is optionally followed by the same sequence identifier (and any description) again.
• Line 4 encodes the quality values for the sequence in Line 2, and must contain the same number of symbols as letters in the sequence.
