Alternatives and detailed information of Prsice

PRSice (pronounced ‘precise’) is a software package for calculating, applying, evaluating and plotting the results of polygenic risk scores (PRS). PRSice can run at high-resolution to provide the best-fit PRS as well as provide results calculated at broad P-value thresholds, illustrating results corresponding to either, can thin SNPs according to…

How to find out why PRSice-2 excludes ambiguous SNPs

How to find out why PRSice-2 excludes ambiguous SNPs 0 When I use PRSice to calculate PRS,it alerts it excludes 25 SNPs from the base data. But how could I know the reason why they are ambiguous? Could I explore more why they are ambiguous? Question2: If I use PRSice…

Do we need to apply the same p-value threshold on all 22 chromsomes?

Polygenic Risk Score Calculation: Do we need to apply the same p-value threshold on all 22 chromsomes? 1 Hi there, I am using PRSice-2 to calculate the polygenic risk score for 22 chromosomes one by one. To my understanding, since the 22 chromosomes are independent of each other, and our…
