LD Reference Data: Custom Data

BridgePRS requires genotype data in PLINK binary format from samples representative of the base and target population GWASs.

To pass user supplied LD reference data for a population named POP, create folder a (named POP_ld) which includes:

• A .bed, .bim, and .fam file for each chromosome with format "chr"[1-22]".ext"
• POP_ids.txt, a txt file that lists the sample IDs for your population(s)

Then use the command line argument --ld_path to point to the location of this folder on your computer.
