I would like to run the basic command for the meta-analysis as follow: plink --meta-analysis study1.assoc study2.assoc
PLINK will search the header row for the columns:
SNP SNP idenitifier
OR Odds ratio (or BETA, etc)
SE Standard error of OR (or user-defined weight field)
P (Optional) p-value from test
My problem is that file 2 (study2.assoc) does not contain SE (standard error) numbers. File study2.assoc contains three columns named SNP, OR and P. Is there a way to calculate the SE based on these three columns? The three columns is the only information that i have.
I hope that someone can help me with this problem!
