Net: Download version 1.25 here
a program written in C and perl for the creation and statistical analysis of large networks (graphs). Linux version.

ATOM: Download it here
a program written in C for the calculation of the electronic properties of isolated atoms. It relies on Relativistic Density Functional Theory. Linux version only.

FEATURES:

• Text based initialization file
• Graphical interface (if you do not like to edit text and if you have Qt 3.0 installed). Click for a snapshot.


• Import of user network structure data (undirected, directed, weighted networks).
• Creation of tag co-occurrence weighted networks from lists of Tag Assignments.
• Reshuffle of a folksonomy as a null model.
• Creation of a folksonomy by a random walker exploring the semantic network.
• Creation of complex networks using the fitness model of "Caldarelli G. et al., PRL 89, 258702 (2002)".
• Creation of complex networks using the Barabasi-Albert model of preferential attachment.


• Graph reduction with the minimum betweenness criterium.
• Calculation of eigenvalues and eigenvectors of graph associated matrices (requires Lapack and GSL)


• Analysis of most relevant statistical quantities:
• degree distribution
• clustering coefficient
• degree correlation
• site and edge betweenness
• pair distances
• cluster dimensions


• Direct interface with XmGrace.
• Display networks with Graphviz and/or Grip


• Manual.
• A web interface is available running a simplified version of the program.

Send me an e-mail if you would like to have informations on future releases, some minimal help, report bugs. It would also be very kind if you mail me acknowledgements if you find this program useful.
