I have a .geno file, containing genotypes of present-day and ancient individuals (https://reich.hms.harvard.edu/downlo...blished-papers). What I want to do is to use bayenv2 on these data, looking for a correlation between alleles frequencies and a specific environmental variable. In particular, I'm interested only in modern individuals, that is the individuals with "present" in the 7th column of the .anno file. So, what I'd like to know is what I need to do with the initial .geno file in order to obtain a file that is bayenv2 usable and that contains only the genetic information about modern individuals. Thank you.
