There are 1 region(s)/phenotype(s) with p-value > 0.1 (not significant).

I’m trying to get a PRS for a very small subset of samples (~400 training, ~200 testing). Firstly I C+T the training data previous to PRSice.

PRSice-2 using SNPs with extremely low P-value

PRSice-2 using SNPs with extremely low P-value 0 I would like to construct a Polygenic risk score using PRSice-2. However, our summary statistics contains a very small P-value, such as P-value=5.0×10^-1200. Perhaps that is why we cannot use this summary statistics to construct the PRS. How can I solve this…

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…
