answer, even if the literature concerning virtual charges is not a lot, I will keep looking. Best regards: R On 02-04-12, David van der Spoel wrote: > On 2012-04-02 20:29, R.Perez Garcia wrote: > >Dear GROMACS users, > >I would like to place the charge more localized in the "bond

2012-04-02 Thread R.Perez Garcia
Dear GROMACS users, I would like to place the charge more localized in the "bonds region" and not exactly in the atoms. Please let me know if you know there is a way to do this in GROMACS. Thank you in advance, R -- gmx-users mailing listgmx-users@gromacs.org http://lists.gromacs.org/mailman

[gmx-users] center the system on specific atoms type

 Dear all, I am running a simulation in of a fullerene in different solvents. I would like to keep the fullerene somehow centred in the box, so I changed co comm_grps =  System to mm_grps  =  FUL. If I do this the following error pop up: There are:   395  Other residues Analysing residues n

[gmx-users] Charge delocalization fullerene

2012-03-10 Thread R.Perez Garcia
 Dear all, I am trying to realistically de-localize a charge over all the carbon atoms of a fullerene. Up to now I just put 1/60 on each and a contra-ion far away from the bucky ball. I do not believe this is the best approach but i can not think on a better solution as I started with gromacs tw
