mac95.zip
Macaque cortical connectivity network within one hemisphere. The files include the adjacency matrix, the labels of the cortical regions, and the spatial positions of the regions as three-dimensional coordinates (the unit is mm).
celegans131.mat
celegans131.zip
C. elegans local network of 131 frontal neurons. The files include the adjacency matrix, the labels of the neurons, and the spatial positions of the neurons as two-dimensional coordinates (unit is mm).
celegans277.mat

C. elegans global network of 277 neurons. The files include the adjacency matrix, the labels of the neurons, and the spatial positions of the neurons as two-dimensional coordinates (unit is mm).

Artificial networks

autobahn.zip Contains Matlab file with the German highway system network (raw data from Autobahn-Informations-System, AIS from www.bast.de). It includes the adjacency matrix (value 1 if two locations are directly connected by a highway) and the labels of all 1,168 nodes. Please cite the following source for the data: Kaiser M., and Hilgetag C.-C. (2004) Spatial growth of real-world networks. Physical Review E 69:036103. 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. Please cite the following source for the data: Marcelino J. and Kaiser M.

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).

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.
