Hi Hewan,
Could you provide a bit more information? Do you have data provided by DArT? Or have you got called SNP data from another source? DArT datasets come with PIC and MAF already calculated and provided, but I believe you can recalculate them with dartR as well
- say, once you’ve done some QC filtering or similar.
Please refer to the dartR tutorials that are provided. They will help you get started.
Cheers,
Olly
