Summary
Jenti is a tool to mine the pairwise kinship coefficient matrix of complex genealogies with multiple lines of descent and identify clusters of individuals sharing the same expected amount of relatedness through maximum-clique approach. It additionally allows for the reconstruction of sub-pedigrees suitable for genetic mapping in a systematic way (Falchi and Fuchsberger 2007).
Why Jenti?
When dealing with complex genealogies, it is sometimes useful to extract the sub-sample of the most related/unrelated individuals, or to split the whole genealogy in homogeneous sub-samples. Systematic clustering is unfeasible without an appropriate computational tool, because of the massive number of possible configurations.
Features
Jenti explores the kinship relationships among all the individuals and identify the sub-group(s) configuration which maximizes the overall number of extracted pairwise relationships.Through a user-friendly graphical interface, the user is assisted step-by-step in the in the selection process, from the exploration and cleaning of the whole genealogical data to the manual or semi-automatic clustering of individuals in homogeneous sub-groups.
System requirements
Java VM 5.0/1.5 or higher Get Java
(To check Java version, type "java -version")
