Re: [Jmol-users] Generating Periodic Boundary Structure in Jmol for Molecular Dynamics

[Oloriegbe, S. <olo...@mi...>]

Thanks Bob,



I didn't get your e-mail despite configuring jmol to allow me receive mails from the list. I was able to copy your response from the mail list website (see below). I eventually use;



load "filename.cif" {555 555 0} supercell { 8 8 2 } and got a supercell with small box encompassing some of the atoms which appears to be fine with some other noisy residual atoms outside box. When I wrote out the XYZ file, all atoms appears in the output file.



Is there any command that help print out atoms only in the small box of interest?



Suleiman.



{1 1 1} indicates you want a packed cell, which duplicates atoms on faces.

try {555 555 0} instead and see if that helps.

Could anyone on the list help me with getting rid of overlapping atoms on edges, boundaries and corners after generating a superstructure from jmol through a CIF file. The XYZ file would be use as input in Molecular dynamics program LAMMPS.





I use load "filename.CIF" {1 1 1} supercell {8 8 2}. There are 8 atoms per unit cell, so I expect a total of

8* 8 * 8 * 2  = 1024 atoms, but I got 1171 atoms instead.



I took the painstaking method of removing the overlapping atoms visually, but such approach can be plague with errors, so any help doing it automatically using a script would be appreciated.



BTW. I read most of the Jmol documentation and non of the commands seems to help.
