Signal-to-noise ratio (SNR) plotted against the size of the ensemble for inference of a 20 vertices network. (a) Mean SNR for edges inferred from a worst-case GMT file over a range of sample-sizes N
(averaged over 40 inferred networks). (b) Expected SNR for the worst-case GMT file. (c) SNR in the case of GMT files generated by performing 100 short random walks (length 3).
