Hi all,
After filtering and merging data from using --bmerge flag in Plink 1.9, I did use the same thresholds as before merging the dataset to test the quality of the merged dataset. Then I have this "error: All people removed due to missing genotype data (--mind)". Why I loose the quality that I have got from the separate datasets that I have applied the same filter thresholds?
Thank you
Hi chrchang523,
Thank you for your answer. Does it mean that it is no need to test the quality of the merged dataset? and what should be the best way to minimize bias?
