I know there are several ways of calculating LDs using tools like plink when using genotyping data. In my case I've several different loci on the genome that show some sort of interaction. Some of these might have SNPs thus I could use the SNPs LD as a measure though in many other cases I don't have SNPs in the regions of interest. I assume that in these cases some sort of estimation has to be done which is fine for what I want to-do with my data.
Hence, is there a simple way to get LDs between 2 regions on the genome. Samples are CEU and are part of HapMap/1,000 Genomes so data is plentiful. Is there maybe a simple webservice which I could use that already has this kind of information pre-computed or compute on the fly?
