Re: [gmx-users] how to remove periodicity when using g_rmsd

Hi Tangj Jioawei, Erik. This is due to periodic boundary conditions. Make sure your molecules stay together (clustered/nojump) before determining the rmsd. Use trjconv... Tsjerk On 9/27/07, Erik Marklund <[EMAIL PROTECTED]> wrote: > My first guess, without knowing how you used g_rms, is that the

My first guess, without knowing how you used g_rms, is that the larde rmsd for certain subunits is due to inadequate roto-translational fit prior to rmsd-calculation. Does that help? If not, please be more explicit about what you aim to do and what you have done. /Erik 27 sep 2007 kl. 11.2

Dear all, I am studying on a big protein with 16 subunits and when i used g_rmsd to one subunit of the protein, the result seems strange that the structure of the subunit changes much but it should not.. I searched the mailing list and it may be caused by the periodic thing. Could you tell me how t
