A FASTA file represents one or more DNA sequences. It is a simple text format, composed of a greater than sign (>) followed by an identifier, followed by a nucleotide string (actg) on a new line.

For example:

> ID_of_person_A
CCTCAGATCACTCTTTGGCAACGACCCCTCGTCACAATAAARATAGGRGGGCA
ACTAAAGGAAGCTCTACTAGATACAGGAGCAGATGATACAGTATTAGAAGAAC
TRAGTTTACCAGGAAGATGGAAACCAAAAATGATAGGGGGAATTGGAGGTTTT

> ID_of_person_B

The file extension varies (.FASTA, .FAS, .FA). Any file that doesn't have a csv file extension will be parsed as a FASTA file.
