Dear all How can we calculate the rmsd between different monomers from of a protein. for example I have a tetramer and I have to calculate the rmsd between chain A to B, A to C and A to D with time. I was trying using g_rms but couldn't do that. thanks with regards anupam -- Science is facts

Hi, RMSD is given at a specific time, so you can ran g_rms for each residue (create index file witha specific residue in) and then take the RMSD of each residue at time T and plot it. But I think you should look into g_rmsf, this might fit you better, although it calculate the fluctuations rather
