Currently the LD References are restricted to chromsomes 1 - 22 and does not include the ability to provide X, Y or MT chromosomes. This would be a really handy feature to have when generating and providing alternative LD reference datasets, inclusive of other populations. Linked to #1 for limitations in LD reference data to use.

	for(int i = 22; i>0; --i){
	ldfile = gsubstr(ldfile, "chr" + to_string(i), "chr*");
	}
