PEPIS: A Pipeline for estimating EPIStatic effect in Quantitative Trait Locus Mapping and Genome-Wide Association Studies   
Location:  Download

Module Description

  • PEPIS include four function modules: 1) kinship matrix calculation(km_calc), 2) poygenic component analysis(pg_anal), 3) genome scanning for main genetic effect(gs_main), 4) genome scanning for epistatic genetic effect(gs_epis).
  • PEPIS need the additive and dominance genotypic data files as the inputs to calculate the 6 polygenic kinship matrices, and furthermore need the phenotypic data file to estimate the polygenic component ratios and genome scanning for main and epistatic genetic effects.
  • All of the function modules are developed in C++ and have been successfully compiled and tested in our linux system. User can freely download, modify and compile the source code without restriction into their own pipeline.
