US Classification:

435/006000, 702/020000

Abstract:

A pattern discovery-based method for identifying genetic associations in mapping complex traits. In one embodiment, this invention describes the applicable study designs, the pattern discovery algorithm on phenotypic/genotypic data, and methods to evaluate statistical significance of identified patterns. Patterns identified through the proposed methods act as signatures or profiles that can be used to locate genes or genomic regions responsible for the traits of interests in the genome. This invention has been successfully applied to two independent datasets collected from actual genetic studies and has produced significant results.

Inventors:

Zhong Li - Livingston NJ, US

International Classification:

G06F 17/30

US Classification:

707201, 707E17007

Abstract:

The invention is directed to a system and method for merging at least two datasets each having at least two keys and each having a plurality of data elements. The system determines a quantity of shared data elements in each dataset for each key as well as a quantity of unique data elements in each dataset for each key. The system then generates a graphical output representing the quantity of shared and unique data elements in each dataset for each key. The system receives a selection input selecting one of a plurality of merge strategies. Each merge strategy is based on the quantity shared or unique data elements in each dataset for each key. The system then generates a merged dataset containing data elements from the at least two datasets based on the at least two keys and the selected merge strategy.
