I am calculating PRSs using the command:
plink2 \
–bfile plink_file \
–score score_file 1 2 3 header cols=+scoresums,-scoreavgs \
–out PRS_sum
Currently, the columns in my score_file are: SNP IDs, effect allele, beta weights.
I was wondering if possible to give instead of SNP IDs in the first column, chrs and positions (with an extra column)
e.g. a score file with 4 columns: chr, position, effect allele, beta weights. Or a similar structure.
If yes, which flags should be used?
Thank you!
