Hello,
I did my mtDNA with Family Tree, but I think they may be the same.
For instance, on mito search you will see on the left side a 16 in the blank next to it you put in the numbers of after 16 in order with you mtDNA results(for example: 16 123(entered number) then the next drop down box you just click on the letter after each number of your mtDNA. I hope this helps
