One Tip Per Day. Learning notes for Unix, Perl, R, HTML, Javascript, Google API and mostly Bioinformatics. Friday, September 11, 2015. PLINK2 vs. SNAP for linkage disequilibrium (LD) calculation. Among other ways to calculate SNPs in linkage disequilibrium (LD), two methods have been used in many literatures: PLINK2 and SNAP. With PLINK2, SNPs in LD can be calculated using parameters like:. PLINK2 -r2 dprime - ld-window-kb 1000 - ld-window 10 - ld-window-r2 0.8. And the number of SNPs apart ( - ld-window.

It's not a shame to put a note on something (probably) everyone knows and you thought you know but actually you are not 100% sure. Multiple testing is such a piece in my knowledge map. Type I error (false positive) and Type II error (false negative):. When we do a hypothesis test, we can categorize the result into the following 2x2 table:.
