I tried for days to convert a gen file to vcf but it did not work. I am a beginner so i don't know what are in vcf files and gen files or how they work. I saw some tools like samtools or bcftools but it's on linux, i saw other tools but require linux or mac as well. I tried with plink but it says that it need a .sample file and i don't know what is that .sample file. I tried an other tool, fcgene but it gave me an error when i tried to convert to vcf. Do you guys know a simple tool to convert a gen file to vcf or even convert it to 23andme format?
