Calculate saturation on nucleotide MSA

Question

[dago]

Hi would like to check for possible saturation of nucleotide substitution types on several nucleotide MSA.

I know that Xia et al published an index and this is implemented in DAMBE5

However, as far as I get I should submit my MSA one by one in DAMBE, and this would be infeasible for me. Do you know any other methods I could use and iterate in Linux?
