Each element Rij in the AARM represents the ratio of number of replacements of the residue i by the residue j in the forward direction (mouse
human) to that in the reverse direction. This means that if Rij >1, the number of (i)Mouse
(j)Human replacements is higher than the number of (j)Mouse
(i)Human replacements and if Rij p
