How to calculate the Delta Phi Psi value i.e Difference in Phi and Psi values for the aligned residue pair between Reference protein structure and Target Protein Structure in Proteins?
I aligned multiple protein structures from the same protein family to a reference structure and now I want to calculate the Difference in Phi psi values for 'aligned' residue pair between Reference Structure and each Target Structure, I have extracted the phi psi values using phi_psi command and I have the sequence alignment but I don't know how to extract Delta Phi Psi values for every aligned residue between Reference and Target.
