ControllabilityAnalysis: This is the C++ code accompanying the paper by Liu Y-Y, Slotine J-J, Barabási A-L. Controllability of complex networks. Nature (featured as a cover story) 2011;473:167–173. It will parse any two-column edgelist file and perform the controllability analysis, reporting the number of driver nodes, node classifications, link classifications, etc.

CalControlCentrality: This is the C++ code accompanying the paper by Liu Y-YL, Slotine J-J, Barabási A-L. Control Centrality and Hierarchical Structure in Complex Networks. PLOS ONE 2012;7:e44459.. It will parse any two-column edgelist file and calculate the control centrality of each node in the network.

MotifAnalysis: This is the Mathematica script accompanying the paper by Angulo MT, Liu Y-Y, Slotine J-J. Network motifs emerge from interconnections that favor stability. Nature Physics 2015;11:848-852. It will perform network motif analysis from real networks and their condensations. 

Qualitative Flux Control (QFC) Analysis: This is the Matlab package accompanying the paper by Basler G, Nikoloski Z, Larhlimi A, Barabási A-L, Liu Y-Y. Control of Fluxes in Metabolic Networks. Genome Research (featured as a cover story) 2016;26:956-968. It will calculate the driver reactions of metabolic networks. 

Dissimilarity-Overlap Curve (DOC) Analysis: This is the Matlab package accompanying the paper by Bashan A, Gibson TE, Friedman J, Carey VJ, Weiss ST, Hohmann EL, Liu Y-Y. Universality of Human Microbial Dynamics. Nature 2016;534:259-262. It will quantify the universality of human microbial dynamics by performing the DOC analysis over OTU table. 

Entropy-based consensus clustering (ECC): This is the Matlab package accompanying the paper by Liu H, Zhao R, Fang H, Cheng F, Fu Y, Liu Y-Y.  Entropy-based Consensus Clustering for Patient Stratification. Bioinformatics 2017;btx167:1-8. It will perform entropy-based consensus clustering, using multiple data types. 

Articulation Point (AP) Analysis: This is the C code accompanying the paper by Tian L, Bashan A, Shi D-N, Liu Y-Y. Articulation Points in Complex Networks. Nature Communications 2017;8:14223. It will perform the Greedy Articulation Points Removal (GAPR) decomposition for real networks. 

Ecological Network Reconstruction (NR): This is the Matlab package accompanying the paper by Xiao Y, Angulo MT, Friedman J, Waldor MK, Weiss ST, Liu Y-Y. Mapping the ecological networks of microbial communities. Nature Communications 2017;8:2042. It will reconstruct ecological network of microbial communities from steady-state data.
