Thank you for your suggestion Alessandra Villa I have applied all types of pbc conditions but my one peptide is diffusing away from another peptide in case of dimer after half of the simulation time and rmsd is coming out 100 Angstrom after that time which is very high. Please suggest me what shoul

Hi, I suggest to visualize your trajectory. Maybe one of the peptide is diffusing away from the other. Or the one peptide is jumping in and out or moving out the box. If it is the case, here you found some trjconv workflow http://www.gromacs.org/Documentation/Terminology/Periodic_Boundary_Condition

Dear all, I have calculated the c-alpha RMSD of dimer having 7 residues peptide each by using command gmx rms. But the calculated RMSD 14 Angstorm is very high, although I have applied all pbc conditions. Anybody can suggest me why so much high RMSD is coming or is it possible. -- Ashma Khan Rese
