    Great tutorial... I have learned how to convert HAPMAP format into Vcf format file from your tutorials. But, can you please clarify me how to get population text/ grouping details.?
    or is the Population text are gropuping result of Population structure analysis?

      Grouping information was not from structure software. For teaching purposes, individuals were randomly divided into groups.

    Very nice video. Now that the QC work is completed and we have cleaned data in various formats, such as.vcf, could you please show us how to use it for GWAS analysis with the rMVP package?

    A very detailed and helpful video! About the parameter you chose for --indep-pairwise command, is there any good tutorials or guidelines for that? For example, how to choose the window size (50 in the video)? How to choose the threshold for r^2 (0.2 in the video)?

    Is the vcf file a merged from individual vcf files of 36 genotypes or is it concatenated one?
