Pre Imputation Quality Control (QC) Protocol - Updated (April 16, 2024). This protocol explains first different scenarios related to different levels of previous genotype processing (e.g., if you have contributed to previous ENIGMA GWAS versus if you have not previously processed (all) the genotype data). Please note: This Pre Imputation QC Protocol is meant to be run after you have completed the ENIGMA DTI phenotype extraction and QC protocols found here.
