The file lcloning.py provides the function save_lcloned_edgelist that reads an edgelist from a textfile, generates a random L-cloned graph, and writes its edgelist into a new textfile. The original graph is assumed to be simple, unweighted, undirected and without self-loops. The name of the copies of each vertex in the L-cloned graph is appended "_##", where ## corresponds to the layer's number (between 0 and L-1).

The function can be called from another script

from lcloning import save_lcloned_edgelist

save_lcloned_edgelist(original_el_fname, l_cloned_el_fname, L, sep, comment, header)

where

original_el_fname : string
    path to the file containing the original edgelistin which each line
    corresponds to an undirected edge. The name of the two vertices are
    treated as strings and must correspond to the first two columns of
    each line.
l_cloned_el_fname : string
    path to the file that will contain the L-cloned edgelist
L : int
    number of copies
sep : string (optional; default: any white space)
    character(s) used to separate the columns on a single line
comment : string (optional; default: #)
    any line beginning with this character is ignored
header : bool (optional; default: True)
    add a header to the l-cloned edgelist

or can be executed by running

python lcloning.py original_el_fname l_cloned_el_fname L
