Composite risk score in GWAS using snp weights

Question

[datanerd]

HI All,

I have a list of SNP with weights (provided) and I have another dataset genotype with phenotype known. Iam supposed to calculate the "composite risk score" from this new dataset (have plink files) using the SNP weights provided. Whats tools/programs can I use? Is there a tutorial out there?

Thanks so much!! Mamta
