I need to read data from two data files
and create a box consisting of atoms. I don't know hot to change atom
coordinates so that they do not interfere with each other.I want to have
one system above the other in one box. I thought one way could be
increasing one box dimension (in z direction) in the first data file and
then reading the next data file and simultaneously using the "shift"
option to shift the positions of atoms. Is there any other way to do
it? what about the "boundary m" option? Is it helpful to determine
flexible box dimension?
