Resources of the IOSSIM

IOSSIM (Insect Olfactory System Simulator) is a software system developed for K computer. This system was developed as one of the projects for "Research and Development of Next-Generation Integrated Life-Science Simulation Software (ISLiM)" supported by Next-Generation Supercomputer Project of MEXT.

IOSSIM contains following one series of database and three softwares
1.Bombyx Neuron Database; BoND/IVBPF)
2.KNEWRiTE: sofotware for extracting neural structure of individual neurons
3.NEUROREGISTER: software for generating a neural network in a standard brain
4.NEURON_K+: software for simulating a large-scale neural network

        Figure 1. Structure of IOSSIMの構成

This database contains physiological and morphological properties of more than 1600 brain neurons of male silkmoths (Bombyx mori).This database is partly open for public. Publised database

Extraction software of neuron structure. PC based software. Working on windows/linux conditions.

How to install NEURON_K+

1. Uncompress NEURON_K+.
  > tar xvzf neuron_kplus_release[version].tar.gz

  > mv neuron_kplus_release[version].tar.gz neuron_kplus

2. Download original NEURON source codes and move.

  > wget http://www.neuron.yale.edu/ftp/neuron/versions/v7.2/nrn-7.2.tar.gz"
  >http://www.neuron.yale.edu/ftp/neuron/versions/v7.2/nrn-7.2.tar.gz%3C/a%3E%3Cbr />

  > tar xvzf nrn-7.2.tar.gz

  > mv nrn-7.2 neuron_kplus/nrn

3. Apply the patch to the NEURON.

  > cd neuron_kplus

  > patch -p0 < neuron_kplus_release[version].diff

4. Make MOD file compiler.

  > cd nrn

  > ../config_sh/config_mod_[machine].sh

  > make

  > make install

5. Make NEURON.

  > ../config_sh/config_nrn_[machine].sh

  > make

  > make install
