EX_EHO 
P_{c}: proportion of C in the training set; r_{c}: global rate of C; P_{C}/LG: correlation of C aminoacid frequencies compared to LG frequencies; R_{C}/LG: correlation of C and LG exchangeabilities using log values (exchangeabilities are highly contrasted with some very small values);Q_{C}/LG: correlation of C and LG rates using log values. 
Equilibrium aminoacid frequencies: P_{C} 
Exchangeability matrices: R_{C}
