PGS Catalog utilities

This repository is a collection of useful tools for working with data from the PGS Catalog. This is mostly used internally by the PGS Catalog calculator, but other users might find some of these tools helpful.

Overview

download_scorefiles: Download scoring files by PGS ID (accession) in genome builds GRCh37 or GRCh38
combine_scorefile: Combine multiple scoring files into a single scoring file in 'long' format
match_variants: Match target variants (bim or pvar files) against the output of combine_scorefile to produce scoring files for plink 2

Installation

$ pip install pgscatalog-utils

Quickstart

$ download_scorefiles -i PGS000922 PGS001229 -o . -b GRCh37
$ combine_scorefiles -s PGS*.txt.gz -o combined.txt

The pgscatalog_utils package is developed as part of the Polygenic Score (PGS) Catalog (www.PGSCatalog.org) project, a collaboration between the University of Cambridge’s Department of Public Health and Primary Care (Michael Inouye, Samuel Lambert, Laurent Gil) and the European Bioinformatics Institute (Helen Parkinson, Aoife McMahon, Ben Wingfield, Laura Harris).

A manuscript describing the tool and larger PGS Catalog Calculator pipeline (PGSCatalog/pgsc_calc) is in preparation. In the meantime if you use these tools we ask you to cite the repo(s) and the paper describing the PGS Catalog resource:
