Autosomal Tools

← All Topics

Overview (all platforms)

DNAGedcom has several tools that works with the Autosomal Data that you gathered from the different DNA Companies.

Most of the newer tools are built directly into the DNAGedcom Client which runs on your own machine. Here is a view of the tools from the Client.

We also have a list of legacy tools that run on the old DNAGedcom Web Site.

DNAGedcom Client Tools

The types of tools available to the Client vary by vendor.

Collins Leeds Method (CLM)

The Collins Leeds Method (CLM) Tool uses a grid (often called a matrix) to show your matches arrayed in groups (clusters). Membership in clusters is based on matches sharing other matches in common (ICW) with your selected kit. Cluster members share a common line of descent within a few generations, often even the same ancestors. You may optionally show ICW matches that do not meet the criteria you have set for inclusion in clusters.


The CMA Tool uses a matrix to show your matches in clustered groups sorted by chromosome and segment address. CMA requires match, ICW, and chromosome data be gathered with the DNAGedcom Client. FTDNA, 23andme, Gedmatch MyHeritage data are currently supported. CMA can analyze data in the database or, alternatively, CSV files reported by the Client. CMA creates two kinds of output: HTML and Excel formatted matrices.
