Further information on how the network was derived can be found in that article (PDF). |

air500.zip | Flight connections for the top 500 airports, based on total passenger volume, worldwide. The existence of flight connections between airports is based on flights within one year from 1 July 2007 to 30 June 2008. The zip file include the matrix of connections between airports as well as a list of airport codes for each network node (csv files). It also includes a Matlab .mat file with the same information.

## Program code

SIngular NOde MOtif detection | Matlab/Octave code for detecting singular node motifs (characteristic nodes of a network). Documentation of the routines can be found here. If you use these algorithms, please cite Echtermeyer C, Rodriguez F, Costa FdL, Kaiser M (2011). Automatic network fingerprinting through singular node motifs. PLoS ONE 6(1):e15765 (PDF) and Costa LdF, Rodrigues FA, Hilgetag CC, Kaiser M (2009). Beyond the average: detecting global singular nodes from local features in complex networks. Europhysics Letters 87:18008 (PDF). |

Hierarchical networks | Matlab code for generating hierarchical networks, simulating activity spreading, and calculating the proporation of simulation runs with limited sustained activity (LSA). These routines were used for the article Marcus Kaiser and Claus Hilgetag (2010). Optimal hierarchical modular topologies for producing limited sustained activation of neural networks. Frontiers in Neuroinformatics (PDF) |

ADAPA | Adapa is a free reusable tool to run parallel applications on multiple computing platforms, while being flexible enough to allow its users to use any familiar programming languages that they are acquainted with. The tool has been applied to the computation of correlation networks of multi-electrode array (MEA) recordings, see Pedro Ribeiro, Jennifer Simonotto, Marcus Kaiser and Fernando Silva (2009). Parallel calculation of multi-electrode array correlation networks. Journal of Neuroscience Methods (PDF) |

sng.m | Matlab script for spatial networks generated by spatial growth. For details on the algorithm, look at Kaiser M., and Hilgetag C.-C. (2004) Spatial growth of real-world networks. Physical Review E 69:036103 (PDF) |

Kaiser2008NJP.zip | Matlab scripts for (1) the clustering coefficient definitions C1, C2, and C’, (2) the indirect definition disconnectedness D, and (3) the inverse generation of small-world networks starting with a random network instead of a regular network and therefore generating a higher percentage of leaf and isolated nodes. For details on the algorithms, see Kaiser M. (2008) Mean clustering coefficients – The role of isolated nodes and leafs on clustering measures for small-world networks.
