Hello,

Initially, I have had a vcf file, then used PLINK to turn it into three plink binary files (i.e., BIM, FAM, and BED).

Next, for FAM file, I only preserved samples of my interest using R (from 504 samples, now I just have 503 samples).

The same for BIM file, I only kept variant IDs of my interest using R too (from about 3 mil. IDs, now just have 18 IDs).'

Right now, I dunno how to have a new BED file accompanied with two new files FAM and BIM.

Please help me. Thanks in advance
