  • Basic bioinformatics for dummy

    Hello everyone,

    My study involove GWAS methods in tomato. I genotyped 109 lines for 7720 SNP markers and I have the results in excel and here is small example:
    SNP NAME CHR POSITION sample1 sample2 sample3............

    the SNP scores are in IUPAC format.
    I want to start GWAS this data together with 70 phenotypes and first thing that I need to know is what is HAPMAP format and how can I do it by myself.
    I read that every GWAS algorithm need this first stage.
    Please explain it as simple as you can


    Thanks,
    Itay
