My research question is about a protein that is a homo dimer (Two monomer units having chain A and B respectively) Now, we are trying to see the mutational effects in both monomers (same residual position) at the same time (chain A and B respectively). But when I am giving input in DynaMut2 for both the chains then it gives an error while when I give the input for single chain A or B having multiple (two positions) mutations (within the same or single chain) it gives me an output (result) file. so Through this what I can conclude is that DynaMut2 only identifies multiple mutational effects in a single chain OR in other words it is not designed to identify multiple mutational effects belonging to different chains. Please help me to fix this problem.
