Model files for the paper "Distributed organization of a brain microcircuit analysed by three-dimensional modeling: the olfactory bulb" by Migliore M, Cavarretta F, Hines ML, Shepherd, GM Frontiers in Computational Neuroscience (2014), doi: 10.3389/fncom.2014.00050 A full HD version of movie 1 of the paper can be downloaded from: http://senselab.med.yale.edu/modeldb/data/151681/movie1.mp4 To run a simulation or visualize the results, the following files need to be placed in the same directory of the main code: fig7.weight.dat c10.dic mitral.dump They can be downloaded from: http://senselab.med.yale.edu/modeldb/data/151681/bulb3d-files.zip -- simulation-- The simulation requires NEURON 7.3 with python. After compilation of the mod files the simulation can be run with a script and a command line that depends on your parallel computer system. For an IBM BlueGene/Q, such as the FERMI system at CINECA (Bologna, Italy), the command line was runjob --ranks-per-node 16 --exe powerpc64/special --args -mpi --args -python --args customsim.py Using 2048 processes the simulation takes about 10 hours. The final weight files need to be compacted with cat fig7.weight.dat.* > fig7.weight.dat -- visualization -- The visualization requires the Enthought.com Mayavi installed.
