Processing data from genotyping chips
Processing genetic data includes receiving two or more genetic data sets for an individual from one or more genetic data sources, wherein the genetic data sets comprises data pertaining to the individual's deoxyribonucleic acid (DNA); merging the genetic data sets from the one or more genetic data sources to obtain a set of merged genetic data for the individual, including: identifying data in the genetic data sets that is conflicting, the identified data corresponding to a genetic marker associated with a variation that occurs at a region in the individual's genome; analyzing the identified data to resolve a discrepancy attributed to the identified conflicting data and automatically determine an appropriate value that corresponds to the genetic marker, the analysis and the determination being based at least in part on contextual information; and storing the appropriate value in the set of merged genetic data.
