General Directions for FASTA format

Full genetic sequences are commonly stored in FASTA format which contains a listing of each nucleotide in the sequence. If you have had your mtDNA sequenced, your testing service (FTDNA, et al.) will usually provide you with your results in FASTA format (and in a shorthand of differences to rCRS which mthap can also use). You can also download public mtDNA sequences from places like GenBank in FASTA format. A FASTA file will look something like this:

>gi|296801958|gb|HM246245.1| Homo sapiens haplogroup U5a2a mitochondrion, complete genome
...(lots more lines)...

(The first line is typically a comment line describing the sequence and there's no set format required other than it start with ">".)

Please make note of the following:

Brief directions for FTDNA users:

  1. Log into your account.
  2. On the top of your "myFTDNA Home" page look for the "mtDNA" section and click on "Results."
  3. Scroll to the bottom of the page and click on the orange "FASTA" button in the bottom right corner of the page.
  4. Save the fasta file somewhere on your computer.
  5. Click on the "Browse" button on the mthap page and select the fasta file.
  6. Click on "Upload."
