FASTQ is a standard file format used for storing biological sequence data, particularly nucleotide sequences from high-throughput sequencing technologies. It is commonly used in genomics and bioinformatics for representing raw sequence reads along with their associated quality scores. A FASTQ file consists of four lines for each sequence entry: 1. **Sequence Identifier Line**: Starts with an "@" symbol followed by a unique identifier for the sequence. It may also include additional information such as the name of the sequencing machine.
