Dear All I want to extract only unlinked snps only, how can do that? After the filter I have around 900 snps, among all the snps 480 snps are unlinked snps , I want to get a vcf files with only unlinked snps only. Any suggestion?

Kind Regards Safi

Ok, sounds like you want to LD-prune then? This post might help Plink: Understanding LD Clumping vs Pruning

as 4galaxy77 suggested, there are a million pre-written solutions to this. can just google this search query and find a software you like. ' if you have a more specific request, like I want to LD prune while also optimizing for this, that might be more appropriate for this forum
