Re: [gmx-users] periodicity and correct output

2010-07-28 Thread Shuangxing Dai
I think I met the same problem. When apply periodicity to the system, some
atoms will translate to the other side of the box, and this gives wrong
polarization values (especially in dynamic simulations). Anyone has idea how
to prevent this and get correct polarization in dynamics?
Thanks,

 Hi,

 Is there an option in any gromacs utility to apply periodicity to the
 output configuration or trajectory? I want to get all the coordinates
 just within an elementary box, between 0 and LBOX in spite of any
 details of the system.

 For example, editconf -no(pbc) does not do its work since after
 processing negative coordinates are sometimes present as well as those
 bigger than LBOX.

Hi Shuangxing,

For my case, I wrote a script just to do +/- LBOX when xLBOX || x 
0. I am not well familiar with polarization algorithm in gromacs but
it seems not to be a problem during a run since mdrun applies PBC at
every step. Maybe I am false here...
