[ESPResSo] How to fill simulation box with copies of complex molecule which was read in from file ?

[Marek Maly]

Dear all,

let say that I prepare external block file with the structure (positions,  
covalent bonds, types of particles) of
one complex molecule X (let say specific hyperbranched polymer).

If I use the right block format I should have no problems to load this one  
molecule into espresso using
blockfile command.

But let say that I want to put into simulation box several of such  
molecules not just one.

What is the best way how to do it in actual version of the Espreso ?

Is there for example some COPY command which is able to copy whole  
molecule X
INCLUDING BONDS and put it in some shifted position in simul. box ?

If one does not care about the bonds, it is very trivial task.
Also copying of the bonds should not be not so big problem
just using "part $i print connections" to learn connectivity
of the particles of original molecule and create the same connections in
particles which belong to new molecule. But OK, this approach is possible
but if there already exist some simple COPY function which is capable to  
create
copy of the original molecule (including all relevant properties for  
example all, potentials (bond, angle, dihedral) )
I would really prefer it.


Thanks a lot in advance for any valuable suggestion !

Best wishes,
