Hello,

I have the following type of file

ID     var  Beta_1 Beta_2 Beta_3 .... Beta_100
rs1     A    -0.6       0.0   0.3 ...    0.2
rs2     G     0.4       0.2   0.0 ...   -0.7
...

I would like to use the --score function of plink to compute PRS for each column.

My main problem is that I can run plink column by column with something like plink --vcf chr1.vcf.gz --score score.txt 1 2 3

But that requires loading each chromosome per column Beta_k which takes a lot of time. Is there a simple way to parse the different columns and to compute the prs for each column?
