BRAPH: A graph theory software for the analysis of brain connectivity

Fig 3

BRAPH workflow.

Workflow for a graph theory analysis in BRAPH and relative graphical user interfaces (GUIs). A) The brain regions are defined in the GUI Brain Atlas. B) The data of the subjects are imported in the GUI Cohort and the user can define groups and edit their age, gender and other relevant data. C) The connectivity matrix is calculated in the GUI Graph Analysis after selecting the parameters defining the type of correlation, how to deal with negative correlation coefficients, and which type of graph to analyze: D) binary undirected graphs at a fixed density (GUI Graph Analysis BUD); E) binary undirected graphs at a fixed threshold (GUI Graph Analysis BUT); F) weighted undirected graphs (GUI Graph Analysis WU).
