What do you mean? The methodology have to be force field independent. Why would alchemical FEP not work if you use another force field?

Dear Sir

I have followed the tutorial "A Tutorial on Alchemical Free Energy Perturbation Calculations in NAMD" section 3 :Mutation of tyrosine into alanine"
I have trying to calculate free energy perturbation for mutating protein.
My main problem is i am using amber topology.
Is there any alternative for this methodology to be used in amber format?

Best Regards
