Help Collins Leeds Method Tool

Overview

---

The Collins Leeds Method (CLM) Tool is a tool used to cluster your matches together by their relations to each other.

Using your FTDNA, 23andMe and My Heritage data, you can create a grid that will show you how your matches match each other. Other companies are coming soon.

Basic Options:

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.

Kit Filter

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"

DNA Kit

You can select any kit that you have gathered for FTDNA, MyHeritage, 23andMe, or GEDMatch.

In addition, you may also select the option to choose a Generic or FTDNA Match/ICW File combination.

Match File/ICW File

These fields only appear if you have selected the Generic 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:

• You can modify the Match or ICW files to eliminate unwanted matches. Note: You only need to remove it from one file or the other to be excluded (but both is fine, too)
• You can save your Match and ICW files before doing a gather, to get a "snapshot" of your current data to be able to run again in the future to compare against the latest results.

cM Range

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.

Inclusion Threshold

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.

Sort

The way matches within each cluster

• By Inclusion - those who match the most others within the cluster will be in the upper-left corner.
• By cM - those who match the primary kit by the highest cM will be in the upper-left corner.

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.

Cluster Sort

The order in which the clusters appear in the chart

• By Size - The clusters will appear from largest to smallest
• By cM - The clusters will appear in order of the maximum cM match to the primary kit.
• By Size, Superclustered - By Size, but as each cluster is placed, others that have a significant amount of cross-cluster matches will appear near it. Superclusers are bordered with a lighter border than full Clusters.
• By cM, Superclustered - By cM, but as each cluster is placed, others that have a significant amount of cross-cluster matches will appear near it. Superclusers are bordered with a lighter border than full Clusters.

Include Unclustered Matches

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.

Paint Midline

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.

Open HTML When Done

Advanced Options

These options require a Genetic.Family account and the local web service be started under the DNAGedcom Client Settings Page.

Include/Exclude Tags

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.

Tag Grouping Options

Selecting one of these options will modify how Clusters or Superclusters are built.

• Weight Tags Closer - This will adjust the weight a match has when determining inclusion. For example, if a Cluster has 9 people, a Match who matches 4 within it would be exluded under 1/2 inclusion. However, if some of those 4 are tagged with the same tag as the Match, it could be included.
• Force Tags Clustering - When building a Cluster, this will force in any single Match that matches someone within that cluster and shares a tag.
• Supercluster Tags - When building Superclusters, Clusters that share common tags will be weighted closer together, in addition to the usual cross-cluster comparison. Those who match tags and have some cross-clusters will be even more likely.

CLM Output

The primary output of the CLM is an HTML file, with an Excel file also generated in the same folder.
