In the example in the documentation the time series is copied to an
empty graph, which will be the starting point of the reconstruction.

This is not controlled explicitly; after you generate the time series
you count the number of times each node flipped, and you average.

Since the Ising reconstruction expects uncorrelated samples, I think
it's best to use only one "time series", i.e.
si_state = gt.IsingGlauberState(g, beta=.02)
ss = [si_state.get_state().copy()]
for i in range(1000):
si_state.iterate_async()
ss.append(si_state.get_state().copy())
ss = gt.group_vector_property(ss)
Best,
Tiago
