Hi everybody! I suceeded in extracting the sub-matrix containing just the relevant subjects of this example data (indeed I could retrieve 190 of the 220 subjects of the data example, so that the relative kinship matrix is a 190X190). For the subjects non present in the kinship matrix case-control kinship coefficient is to be supposed as 0 (zero) - no relatedness. I attach this example kinship matrix.
