The KGraph is a data visualization system that has been developed to display the complex relationships between both univariate and bivariate associations among an outcome of interest, a set of covariates, and a set of genetic factors such as single nucleotide polymorphisms (SNPs). It allows for easy viewing and interpretation of genetic associations, correlations among covariates and SNPs, as well as information about the replication and cross-validation of the associations. The KGraph allows the user to more easily investigate multicollinearity and confounding through visualization of the multidimensional correlation structure underlying genetic associations. It emphasizes gene-environment and gene-gene interaction, both important components of any genetic system that are often overlooked in association frameworks. KGrapher is a tool for easy creation of KGraphs.

Operating Requirements
KGrapher requires a Java RunTime Environment version 1.5 or greater. The authors have only tested KGrapher in Windows and Linux with the Sun JDK 1.5.007. Other version on other platforms of 1.5 compliant JDKs or JREs should work, but have not been tested. To download Sun Java 1.5 go to http://java.sun.com.

Background Information

This software was developed using U.S. goverenment grant support at the University of Michigan in the School of Public Health by Dr. Sharon L. R. Kardia's lab staff.

Note for Internet Explorer Users
For security reasons Internet Explorer will rename "KGrapher_1.0.jar" automatically to "KGrapher_1.0.zip" after downloading KGrapher. In order to use KGrapher, rename the downloaded zip file to "KGrapher_1.0.jar". Please note that you must have Windows Explorer configured to show file extensions to correct this issue.
