This is Part 2 of the DNA Explosion. There are new DNA tools coming all the time.
That plus CeCe Moore’s workshop in August gives us a lot of new possibilities
to share. If you are a beginner, you can
pass this by. Otherwise, these are tools
that can make your DNA pursuit easier. We
will discuss some at our monthly meeting on 9/17.
CeCe starts by defining triangulation which is the use of
three matching DNA testers to identify a cluster or group. There are two types. Pedigree triangulation is matching family
trees. Segment triangulation is matching
segments of DNA. CeCe and also Diahan
Southard promote Pedigree triangulation as the most efficient and effective way
to form “genetic networks”.
Genetic Networks are created using the shared match tools
at Ancestry and other testing websites.
To keep track of her information CeCe said she uses mostly
the Note feature of AncestryDNA and a spiral notebook. I am
using the Note feature for the first time. Before I avoided them because
that info seemed hidden with no way to take out for analysis. One help
for this is the MedBetter Chrome extension (or add-in)
described below.
Many people have been disappointed with the lack of tools
at AncestryDNA. Some are so disappointed
that they write their own programs and provide them to everyone. Everything I am describing is free unless
noted.
Today I will mention two Chrome add-ins and some other
programs. A Chrome add-in is a program
downloaded from the Chrome Store that works with the Chrome operating system. They can’t change your DNA data or results
but can change the way they are displayed.
MedBetterDNA
has been written by Devore Software. It
is only for AncestryDNA. I am one of the people who thought it was awkward to
see the Notes feature. MedBetter
displays any Notes you have entered on the Main Match List page. It also lets you remove the "no
tree" folks from the Match list and filter hashtags that you have used in
Notes. To find this google “Chrome
Store” then search for medbetterdna.
DNA Match Labeling
is another Chrome add-in. It is by
DNA Central, Blaine Bettinger’s group.
Many people wanted a way to group Ancestry matches. This add-in gives you 8 colored dots that
display on the Match List. You can use
the colors to identify family lines or genetic networks. To find this google “Chrome store” then
search for DNA Match Labeling.
CeCe mentioned that Dana Leeds recently took CeCe's week-long
class. Then Dana developed a method of "color
clustering" genetic networks. Some are calling this the Leeds
Method. At the time of our workshop CeCe hadn't had time to look
at it but expects to like it. It is well-explained in three posts at
http://danaleeds.com/. It
uses color on a spreadsheet to identify genetic networks. There are also
some posts at her blog http://theenthusiasticgenealogist.blogspot.com/.
Instead of a notebook like CeCe, I use Excel spreadsheets.
If you aren't using spreadsheets and want to start, I will
help. It is especially useful if you want to sort your information.
Another brand-new
tool is DNA Match Manager. This free tool from Heirloom Software
lets you quickly and easily download your DNA match information from:
Ancestry
(multiple tests supported)
23 & Me
Family Tree DNA
GedMatch (multiple
tests supported)
This creates a
.csv (comma-separated values) file which can be loaded into a spreadsheet.
Match Manager
is fast. It downloads tens of thousands of DNA matches from
multiple sites in record time. It
replaces some older tools like Ancestry Helper.
Don’t use Ancestry Helper. It
takes all weekend.
As I said, this is new. I
had some trouble with it so ask for help if you go down this path.
DNA
Painter is another new one. It
paints chromosome segments which is complicated. The best feature is the shared cM tool which can help you to narrow down the possible
relationships for a match based on the number of centimorgans you share with
them. Click on the “shared cM tool” link
above to go straight to it.
There are three other programs: GedMatch (premium tools $10 per month), DNAgedcom ($5 per month) and
Genome Mate Pro. These are more
complicated and we can investigate those with you as you progress.
I know this is all over-whelming. When you are ready, there are Genies to help
you.
