[gmx-users] gmx genconf

[Alessandra Villa]

Hi,

gmx genconf is not generating xtc files.  -trj  option allows to use the
trj frames to expand  gro/pdb files.
For example using   -nbox 2 2 2 the first 8 frames of the trj file will be
use to build the new gro/pdb file.

A possible alternative is to use If you want to visualize you xtc-file
extanded in x, y, z direction, you could use VMD.
Go to  graphics > representation >  periodic
and then select the directions and the n of images that you desire.

Best regards
Alessandra
