Perl script for calculating AIC, AICc, BIC, and Akaike weights for nucleotide substitution models. Likelihood scores under different models are estimated using PHYML (Guindon and Gascuel, 2003). A difference between Modeltest/MrModeltest2 and MrAIC.pl is that MrAIC.pl does not evaluate all models on the same, approximate topology. Instead, PHYML is used to try to find the maximum of the likelihood function under all models. This is essential for calculating AIC, AICc, and BIC.
