Re: [AMBER] Pdb file to Mol2

It is a DNA seq, that I have derived by Nab command in pdb format.
My goal is to find the mutations in the DNA sequence that could ruin the DNA-Protein interaction completely based on this article "Predicting the Effects of Basepair Mutations in DNA-Protein Complexes by Thermodynamic Integration" . My intended protein is a transcription factor that is derived from Protein data bank in PDB format.
But I am just completely lost through my way!!!! :( :-/
What is the best solution for this study!??
I was supposed to end up this prediction in 1 week, But in this one week I have just gone through the amber tutorials and tried to resolve some basic errors :D with no result!
By the way, I have amber tools 2015 installed.

Hi,

I don't know offhand what a TIW simulation is. Can you be more
specific about your system (name, PDB ID, etc), and what the goal of
your study is?
