I don't have the prior for how the layers should be grouped together. I suppose I need equation 18 also? Are all of these implemented in graph-tool? If so, can you specify the functions in graph-tool for this? It doesn't seem the LayeredBlockState constructor takes multiple graphs or multilayer graphs as input.Thanks,TimAt 2017-03-28 16:03:56, "Tiago de Paula Peixoto" <tiago@skewed.de> wrote: >On 28.03.2017 01:17, treinz wrote: >> OK.
