GemTools – Estimate Genetic Ancestry

GemTools

:: DESCRIPTION

GemTools provides computationally efficient tools for modeling genetic ancestry based in the SNP information.  GemTools is a package of functions to help the user account for genetic ancestry of a large number of individuals using spectral graph theory and projections to break a large problem into smaller pieces and calculate genetic ancestry information efficiently, i.e., a divide and conquer (dac) strategy.
