Molecules on flat surface by using the package of Atomistic Topology Operations

I'm trying simluate a binding between streptavidin and biotin by this package.

I tried to follow the instruction on this web: http://moleculargeo.chem.umu.se/codes/atom-scripts/

but when I try to work on the second row with streptavidin pdb file:

mineral = replicate_atom(oneunitcell,Box_dim,[6 4 1]); % replicate the unit cell 6x4x1 times

There's an error "Unrecognized function or variable 'Box_dim'." but I've already install the package. So how should I fix it?

Without more carefully reading the help for the code you are using, when I go to that link, it describes Box_dim as a variable.

I assume Box_dim is intended to specify something about the dimensions of a box. (Why does that seem reasonable to me?)

Anyway, I would read the manual! Documentation is put there for a reason. If absolutely no documentation was provided, then good luck. Contact the authors.
