WebApr 2, 2024 · In EA and AA separately, the GENESIS package in R was used to infer population structure. 21 We used the PC-AiR function to extract the first five genotype PCs and used GEMMA 22 to estimate an individual relatedness matrix. Both PCs and the relatedness matrix were included as covariates in the eQTL mapping analysis. WebFor training models using the MeTWAS () and DePMA () models, we recommend keeping the genotype files in binary PLINK format (i.e. .bed/.bim/.fam) and reading in the file using the bigsnpr package.
