vcf file conversion

[FerRacimo]

The GRoSS SNP input file format is very similar to the TreeMix input file format: it just needs 3 additional columns with information about chromosome number, position and SNP ID for each SNP. What I would recommend it to convert your VCF file to Plink format and then to TreeMix input file format (see here: https://speciationgenomics.github.io/Treemix/ for guidance), and then just add the 3 columns corresponding to the chromosome, position and SNP ID (which can be obtained from the intermediate plink *bim file). Note that the link also explains how to prune the data, which is something that is not required for GRoSS (so this can be skipped).
