Yes, of course I know that GROMACS measures things in nanometers and VMD uses Angstroms.
Basically it is in coarse grain representation. In general since the aggregate consist of all the beads. I have taken the entire pdb of the aggregate as in input which should take the end to end distance. Do you think that it the problem of Coarse Grain bead? Or is there anything I am missing? -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
