make BED file from existing BIM and FAM files

Hello everyone,

I have a set on .bim and .fam files by chr and I would like to create the corresponding .bed files. I tried using plink but they require .map or .pgen files as input and I don't have those.

Would you have any ideas on how I can do that ?

Thank you very much for your response

plink

  • bim contains snp information (chr, pos, ref/alt allele)
  • fam contains sample information (ID, gender)
  • bed contains genetic data for SNP (listed in the bim file) and samples (listed in .fam file)
    Thus it's impossible to regenerate a bed file from only bim and fam

Unless you are trying to generate RANDOM genomic data, in which case you should explicitly state that in your question, this question makes no sense. See Nicolas Rosewick’s comment.
