What's new at GEDmatch - i4GG 2018


Videos of me talking about GEDmatch tools at previous i4gg conferences are available from http://i4gg.org/
I also have many blog posts about GEDmatch, see http://blog.kittycooper.com/tag/gedmatch/
My presentation slides are always available at the slides site - slides.com/kittycooper

Links in my slides are all clickable!

GEDmatch has updated their terms of service ...
Immediately after the GSK announcement I changed all my cousin's kits to research and then asked them whether they wanted to be in this database




Changing a kit to research means it will not come up in anyone's one-to-many but can still be used by you in its own one-to-many and in a one-to-one
Some GEDmatch Statistics
- 1.2M kits on GEDmatch + GENESIS
- Daily 900-1000 kits are uploaded
- The Day of the GSK: deletions = uploads
- After GSK, deletions quickly tapered off


Soon GEDmatch will stop taking uploads, but that home page will still be available, time to switch to GENESIS
GEDmatch was founded to let you compare autosomal DNA results from different companies with powerful tools



The problem became that the various companies changed to newer chips and test for different not completely overlapping sets of SNPs

The GENESIS one to many for my LivingDNA kit


Kits uploaded directly to GENESIS get assigned kit ids that start with a pair of random letters while migrated kits keep the A,T,M, and H single letters
My brother's Ancestry kit that was uploaded to Genesis
Kits migrated to GENESIS will show an overlap of 0 with other migrated kits - they are all on the old GEDmatch template and have not yet been cross matched with the Genesis kits

My brother's migrated Ancestry kit


The Genesis home page is attractive and much more compact than the GEDmatch home page


The Edit page for a kit is very intuitive

Functions available at GENESIS so far



FIR only version of my comparison of my brother and my Ancestry kits




GENESIS X one to one, me and my brother

Functions available at GENESIS so far
No Change

old Ancestry chip


Multiple Kit Analysis is only on the Tier 1 menu - but you can always get there by checking the boxes and clicking Visualization Options

The multiple kit selection form lets you add more kits by typing or selecting from your list of kits in a drop down

Same as GEDmatch
Same as GEDmatch
Many new features for Multi Kit Analysis


Being able to do a matching segment search for just the selected kits is a new feature
Being able to do a triangulation for just the selected kits is a new feature




My Chromosome Browser at Genesis

Some new matrix options

the Autosomal matrix is clickable to the one to one

The Fully Identical Region CM's Matrix Comparison - only siblings and other doubly related people have these FIRs

Except for Q matching the Tier 1 tools have the same functionality as GEDmatch


So what is missing in GENESIS??

TAG groups are missing


All the GEDcom related functions are only available at GEDmatch
Some experimental Tier 1 tools
- Relationship Tree Projection
- Triangulation Groups
- My Evil Twin Phasing
Some of the fun not too serious stuff
- Eye Color
- Archaic Matches
More Missing Tools
