The Collins Leeds Method (CLM) Tool is a tool used to cluster your matches together by their relations to each other.
The options screen looks something like this.
If the Advanced Options are missing, you are either not logged in to the Client with a Genetic.Family account, or you have not enabled the Genetic.Family Bridge under the Options page within the client.
Typing in to this field will limit the DNA Kit dropdown to only those kits that have a name containing that input.
For example, to find all kits for John Collins, you may type the full name or just "John"
You can select any kit that you have gathered for Ancestry or FTDNA.
In addition, you may also select the option to choose an Ancestry or FTDNA Match/ICW File combination.
These fields only appear if you have selected the Ancestry or FTDNA Match/ICW File option under DNA Kit
If you select an approriate Match and ICW file for the selected testing company, you can use this in place of a kit from the database. This has a few advantages:
Enter this value to set a limit for the Match's Total cM to the kit selected in the DNA Kit option.
The default value is 50 to 400 cM but try moving it up or down to target matches in certain relationship ranges.
Different ranges will yield different results for different kits, so running it for various ranges may offer more insight.
This threshold is the minimum percentage of people within a cluster a person has to match to be included.
By default, it's 1/2, meaning everybody in the cluster matches at least half of the other people. Try setting it to 2/3 to get more but tighter clusters.
The way matches within each cluster
The default is By Inclusion. Try switching to By cM to be able to see those who match the primary kit the most be sorted near each other.
The order in which the clusters appear in the chart
If selected, Unclustered matches that do not fit into any cluster will paint. This can be helpful, because the cross-cluster matches are still drawn, so you can see partial relations.
Try it out with one of the Superclustered options under Cluster Sort to see where they fall on the chart.
If selected, self-matches will be painted black both in the Excel and HTML pages.
This can be helpful when reordering clusters in Excel to make sure you get the whole cluster.
These options require a Genetic.Family account and the local web service be started under the DNAGedcom Client Settings Page.
If you choose to Include Tags, only the matches which have been Tagged will appear in the list.
If you do not select any Tags, then nothing will be excluded. If you pick all tags, those that have not been tagged at all will not appear, so be careful when choosing your tags.
If you choose to Exclude Tags, then matches which have the selected tags will be excluded from the match, even if they are in the Included tags section.
Selecting one of these options will modify how Clusters or Superclusters are built.
The primary output of the CLM is an HTML file, with an Excel file also generated in the same folder.
This is where you will find your clusters, in HTML format! They are drawn with a dark black border around each cluster and a gray border around each Supercluster. Mousing over any filled square will show the name of the two people involved.
A shaded gray box indicates a Cross-Cluster Match, which is a match between two people in different clusters. You will notice that each is gray, and shaded with the two colors of the associated Clusters. This allows you to see which clusters have relationships between them at a glance.
For each row, you will also have the following information:
If the DNAGedcom Client is runnning and the Genetic.Family Bridge is enabled, you can then view details for the clusters, and add tags.
You can also filter your CLM match list by tags.
For more information about tagging, see CLM Tagging
If you click on a cluster and choose View Cluster, the members of that cluster are shown.
From here, you can:
This is where you will find your clusters, in Excel format! They are drawn with a dark black border around each cluster and a gray border around each Supercluster. A gray box indicates a match between two people not within the same cluster, indicating at least a partial link between clusters.
