How can I create a lgen file which has only one individual genotyped for 300,000 SNPs. I mean in the context of sample ids, what shall I use? I created the lgen, fam files below. Then I used plink 1.9 to generate ped file (log file shown belos). The problem is that genotypes in ped file mismatch genotype in lgen file.
