yeah, it's very simple - assume that your disease is locus 1 - then in
the final screen of LCP enter your "Locus order :" data as
'2 1 3' - where your marker loci are 2nd and 3rd in the pedin.dat file.
LINKAGE should then give you a flanking-marker risk calculation.
we do this on a semi-regular basis, and it works fine. you could
also do a run with locus order "2 3 1" where your two markers are
on one side of the disease gene, but i dont think that will give
you much added information...
