MetaSTAAR (Meta-analysis of variant-Set Test for Association using Annotation infoRmation)
This is an R package for performing MetaSTAAR procedure in whole genome sequencing studies.
MetaSTAAR is an R package for performing Meta-analysis of variant-Set Test for Association using Annotation infoRmation (MetaSTAAR) procedure in whole genome sequencing (WGS) studies. MetaSTAAR enables functionally-informed rare variant meta-analysis of large WGS studies using an efficient, sparse matrix approach for storing summary statistic, while protecting data privacy of study participants and avoiding sharing subject-level data. MetaSTAAR accounts for relatedness and population structure of continuous and dichotomous traits, and boosts the power of rare variant meta-analysis by incorporating multiple variant functional annotations.
R (recommended version >= 3.5.1)
For optimal computational performance, it is recommended to use an R version configured with the Intel Math Kernel Library (or other fast BLAS/LAPACK libraries). See the instructions on building R with Intel MKL.
MetaSTAAR links to R packages Rcpp, RcppArmadillo and STAAR, and also imports R packages Rcpp, STAAR, Matrix, dplyr, expm, MASS. These dependencies should be installed before installing MetaSTAAR.
Please see the MetaSTAAR user manual for detailed usage of MetaSTAAR package. The scripts used to generate results in the manuscript are available on Zenodo.
The whole-genome functional annotation data assembled from a variety of sources and the precomputed annotation principal components are available at the Functional Annotation of Variant - Online Resource (FAVOR) site and FAVOR Essential Database.
The current version is 0.9.6.1 (January 13, 2023).
