 2. Smoothing strength (-b VALUE option): This option specify the strength of the smoothing (`:math:\beta`) of the partitions based on the graph topology (using a Markov Random Field). (`:math:\beta = 0`) means no smoothing whereas (`:math:\beta` = 1) means a strong smoothing (value higher than 1 are allowed but highly discouraged). (`:math:\beta` = 0.5`) is generally a good tradeoff.

 3. Free Dispersion around centroid vectors (-fd flag): This flag allows the dispersion vector around the centroid vector of the Bernoulli Mixture Model to be free to vary for all organisms in a vector. By default, dispersions are constrained to be the same for all organisms for each partition, that is to say, all organisms will have the same impact of the partitioning.

 The curves represent the evolution of the size of the partitions when more and more organisms are added to the pangenome. The plain lines connect medians (crosses) of the resampling distribution while shadows represent the interquartile ranges. Finally, a regression curve is drawn fitting a Heap's law ($F = \kappa N^{\gamma}$).
