Dear Gromacs users!!

I have a lipid - peptide system which I simulated for 50ns. Now in the 
beginning of the simulation the peptide was at the center of the bilayer but 
with time the peptide moved and came very close to the edge. Now near the edge 
it is having the interactions with the images of the lipid bilayer, since pbc 
is on, but when I view it using ngmx then the peptide appears to be lying near 
the edge. 

Is there any way by which I can write the coordinates of the images of the 
lipid bilayer since pbc is on?Using trjconv is not helping me since it moves 
the entire system i.e.
lipid bilayer+water+peptide. So what I am looking for is an option to
get the images atoms so that the environment of the peptide remains
same and at the same time the peptide is positioned near the center of the box. 


Also I carried out an analysis in which I calculated number of water molecules 
around residue 1 which is actually lying very close to the edge (rather 
outside). I think if the pbc is on then the images are taken care of 
automatically and it will already construct image boxes around those residues 
which are close to the edge and then perform the number of water molecules 
around residue 1 calculation?

Eagerly waiting for your responses,
Priyanka.
