We work with distance measures obtained from the conversion of similarity indices for binary data. For example, eight isolates of Fusarium moniliforme obtained from Argentine sorghum and maize were compared in this work. The matrix of distance was constructed to compare 16 different measures and to evaluate the congruence between configurations obtained from alternative distance structures. The relevant information to establish distance between two binary multivariate observations is found in the a, b and (b+c) counts associated respectively with the events of co-presence, co-absence and polymorphic amplification product in each site in the genome that
