Sorry for not posting sample data,
however I have found the
problem: for some reason, igraph ignored zeros in the matrix. There were
four zeros, which resulted in two missing pairs.
When I increase the ids of vertices by one from (0 to 2403) to (1 to 2404), it works.
Plus you were right, that putting not transposed matrix as edgelist just took it as a vector
Thanks,
Zbynek
