As well as trees and chromosome mapping, the site hosts:
Shared cM Tool
An interactive tool to show possible and probable relationships based on centimorgans shared
Beta version with updated probabilities
Cluster Auto Painter
Takes your cluster file and segments files and generates a chromosome map with the segments grouped by cluster.
Inferred segment generator
Copy and paste the segments that you and a close relative share with a DNA match, and this tool will output just the segments that you do not share with the match.
Distinct segment generator New
Copy and paste two or more sets of segments that multiple family members share with a single match. This tool will identify the distinct segments and return cM values for each along with the total cM.
Common segment generator
Copy and paste in two sets of segments. The tool will return just those that are common to all sets.
cM estimator New
Enter the chromosome, start, and end positions and this tool will calculate an estimated number of centiMorgans (cM) to one decimal place.
Individual Match Filter
Paste in segments, and the tool will return the segments and total filtered cM according to the criteria you set
Cluster Formatter
A simple tool to extract a CSV of clusters and matches from your Genetic Affairs or MyHeritage autocluster output.
