I am not sure I am doing the gt.minimize_blockmodel_dl properly, over directed networks. In the plot <http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/file/n4027258/dib_particion_ttt_14.jpg> you can see the yellow nodes 27 and 147 are in the center of the star-like structures. However, with opposite arrows sense. I would expect the same kind of connectivity, then characterized by similar incomming and outcomming connectivity.
That is not how the degree-corrected SBM works. It incorporates the (in,out)-degrees as parameters that are independent of the group memberships. See this paper for a discussion of this model and some alternative variations: https://arxiv.org/abs/1205.7009 For this particular network, you might want to consider using the non-degree-corrected model.
