Hello friends, As Justin replied at carla query about structure deformation after the pdb2gmx & the new number retain till end.
My PDB starts at 24 to 200 aa, While running xmgrace (after complete simulation) the rmsd plot is from 1 to 176aa. I understood by previous mail that gromacs renumbered my pdb file at first step. My question is, Is their any way to get plot from 24 to 200 (as entry in pdb) rather 1 to 174 ?
