Finding significant tracts of homozygosity (TOH) using single nucleotide polymorphisms (SNPs) from a large-scale genome data set can contribute to the discovery of genetic factors related to human diseases. The proposed system helps users to visually examine TOH clusters computed from the underlying patient data, lending itself a convenient and powerful tool for knowledge discovery. I've designed and implement the TOH clustering algorithm based on repeated binary spectral clustering. A hierarchy of clusters is created and represented by a TOH cluster (TOHC) tree. Researchers can investigate the clusters with a special interactive widget, namely navigation rings, which is integrated with a visual cluster explorer. Statistical association study and NCBI genome map viewer are also incorporated into the system. The usability and performance of the system is illustrated with a clinical data set of human cancers.","abstract_html":"I propose a new visual analytics system designed for genetic researchers to study genome-wide homozygosity regions.
