I have a number of 67 marker haplotypes that I want to compare to try and narrow down a MRCA for. Are there any special selections or tweeks that I have to make on this tool to make it work most accurately? Or is it pretty much set to go and all I have to do is copy and paste the haplotypes one above the other in FTDNA order?
