DSTG link graph add connections between real spots?

[RemyLau]

According to the link graph construction description from the paper, the graph should also contain interaction between real-spots.

However, in the current implementation (modified from the original implementation, see Su-informatics-lab/DSTG#16), only the cross interactions between pseudo-spots and real-spots are used.

Line 59 in 9966c47

graph = construct_link_graph(pseudo_st_df, real_st_df, k_filter, num_cc)

Should we add the interactions between real-spots as described in the manuscript in the DANCE implementation? If so, it could be achieved quite easily by simply calling construct_link_graph one more time by passing real_st_df as both first two args and combine the edge list with the old graph.

Caution: be aware that one might need to modify the the new graph node indexes (or pass real_st_df and another copy of real_st_df with offsetted index)

[RemyLau]

The authors have confirmed that we should combine both graphs (see Su-informatics-lab/DSTG#16 (comment)).
