Question about PLINK allelic scoring (PRS)

Question

[wonseok.cchoi]

Currently, I'm trying to use PLINK Allelic Scoring (plink --score).

And it generates four output files.

 *.hh     
 *.log    
 *.profile     
 *.nopred

Does anyone know what's the meaning of each file, and included contents?

Thank you!

This is all well documented, see https://www.cog-genomics.org/plink/1.9/output
