A tool designed to provide fast all-in-one preprocessing for GWAS summary data files.
- pos2rs: This function maps variant information in the CHR:POS:REF:ALT format to the corresponding rs ID.
- rs2pos: Opposite to the pos2rs function, rs2pos maps rs IDs to the corresponding variant position.
- tsv2vcf: This function converts GWAS data in TSV (Tab-Separated Values) format to the standard VCF (Variant Call Format). VCF is a widely used file format for storing genetic variation data, and many downstream analysis tools support direct reading of VCF files. With GWASkit's tsv2vcf function, users can easily standardize GWAS data from different sources into VCF format, enabling seamless integration with the MRanalysis platform.
- vcf2tsv: Opposite to the tsv2vcf function, vcf2tsv converts GWAS data in VCF format to TSV format.
