The PGSToolKit acts as a wrapper tool for several methods and can be used to compute polygenic scores (PGS) for a target population. Current methods for computing polygenic scores require a wide range of different input formats and parameters. This toolkit provides a streamlined and clean alternative by using a fixed data format and parameters, configurable from a single configuration file.
Current supported features are:
- Perform quality control by filtering variants based on imputation score and minor allele frequency.
- Compute polygenic scores using PRS-CS, RapidoPGS and PRSice2 based on GWAS summary statistics.
- Compute polygenic scores using the allelic score function of PLINK2 based on posterior SNP effect sizes.
