Dear Alexander,
Thanks for your answer, regarding the treatment, For example, if my data looks like
p1 p2 p3 p4 p5 p6 j1 1 0 1 0 1 0 j2 0 1 1 0 0 1 j3 0 0 0 1 1 1 j4 1 0 0 1 0 0
are you suggesting to treat it as
j1 j2 j3 j4 p1 p2 p3 p4 p5 p6 j1 0 0 0 0 1 0 1 0 1 0 j2 0 0 0 0 0 1 1 0 0 1 j3 0 0 0 0 0 0 0 1 1 1 j4 0 0 0 0 1 0 0 1 0 0 p1 1 0 0 1 0 0 0 0 0 0 p2 0 1 0 0 0 0 0 0 0 0 p3 1 1 0 0 0 0 0 0 0 0 p4 0 0 1 1 0 0 0 0 0 0 p5 1 0 1 0 0 0 0 0 0 0 p6 0 1 1 0 0 0 0 0 0 0
to be an adjacency matrix ? Thanks,

Incidence matrices can be trated as a subset of an adjacency matrix (and in this sense hypergraphs as a special case of graphs), so in principle there is no problem to work around. You just need to properly interpret the model in terms of membership to hyperedges instead of connections to nodes.
You should hardcode the bipartite structure when running the DL minimization in order to save processing time (see the pclabel param).
If you're convinced that this doesn't suite your needs, you should explicitly formulate your conceptual issue so we can provide useful advice.
Cheers!

Thanks Alexander,
May be my question was not clear enough - as you said, my data is already an incident matrix. I would like to use stochastic-block-models, and seems they only work with adjacency matrices. Therefore, I wonder what are the possibilities to work-around this problem.

Ni! Hi Alireza,
One way to work with hypergraphs is to use the incidence graph https://en.wikipedia.org/wiki/Hypergraph representation of the hypergraph.

Hi,
I wonder how one can work with hyper-graphs using graph-tool. For example in my work, I would like to feed a data where rows are journals and columns are papers out-going citations. I understand such a binary matrix, can not be used as an adjacency matrix but I am curious if it is possible to work with this type of input. Otherwise, I appreciate to hear your thoughts on converting this matrix into a adjacency matrix.
