pyhrf.boldsynth.field.genPotts(graph, beta, nbLabels=2, labelsIni=None, method='SW', weights=None)

Simulate a realisation of a Potts Field with spatial correlation amount ‘beta’. ‘graph’ is list of lists, ie a neighbors for each node index. ‘nbLabels’ is the number of labels ‘method’ can be either ‘SW’ (swensdsen-wang) or ‘gibbs’
