# Simulators

An overview of the main target simulators for models in OSB

**Note: not all simulators will be able to execute all models.** See [here](https://v1.opensourcebrain.org/status) for more information on the simulators supported by each of the models on OSB.

For more tools (e.g. for visualization, analysis of models) which can handle the NeuroML elements of the models on OSB see [here](https://docs.neuroml.org/Userdocs/Software/SupportingTools.html).

## Brian

Brian is available for download [here](http://briansimulator.org). There is a [Brian Showcase](http://www.opensourcebrain.org/projects/brianshowcase) project on OSB. 

Greater native support for converting models in NeuroML to (and from) Brian is in development in [NeuroML v2.0](http:///www.neuroml.org/neuroml2). See [here](https://github.com/NeuroML/org.neuroml.export/blob/development/src/main/java/org/neuroml/export/brian/BrianWriter.java).

Brian is also currently supported through conversion of NeuroML models to [PyNN](http://neuralensemble.org/trac/PyNN). See [here](http://www.neuroml.org/pynn).

## GENESIS 2

GENESIS 2 is available for download [here](http://genesis-sim.org/project/genesis).

Support for running NeuroML models on GENESIS 2 is mainly enabled through generation of scripts by [neuroConstruct](http://www.opensourcebrain.org/docs#Using_neuroConstruct_Based_Projects), but see also [here](http://www.neuroml.org/tool_support.php#GENESIS).

## GENESIS 3/Neurospaces

GENESIS 3/Neurospaces are available [here](http://neurospaces.sourceforge.net).

GENESIS 3 currently supports native reading of passive models in NeuroML format (morphology + passive parameters).

Participants at the recent [Workshop on Multi-Scale Modeling in Computational Neuroscience with GENESIS 3](http://www.gradschool.uni-luebeck.de/index.php?id=377) reported some success running neuroConstruct generated GENESIS 2 scripts on GENESIS 3.

## MOOSE

MOOSE is available [here](http://moose.sourceforge.net).

Native support for NeuroML (version 1 & 2) in MOOSE is in active development, but [neuroConstruct](http://www.opensourcebrain.org/docs#Using_neuroConstruct_Based_Projects) can also be used to generate MOOSE code from NeuroML models.

Follow the latest developments in MOOSE [here](http://moose.svn.sourceforge.net/viewvc/moose/moose).

[Moogli](http://moose.ncbs.res.in/moogli/) is a sister project of MOOSE and is a simulator independent OpenGL based visualization tool for neural simulations.

## NEURON

NEURON is available [here](http://www.neuron.yale.edu/neuron). There is a [NEURON showcase](http://www.opensourcebrain.org/projects/neuronshowcase) project on OSB.

There is native support for reading/writing NeuroML cells in NEURON, see [here](http://www.neuroml.org/neuron_tools.php).

[neuroConstruct](http://www.opensourcebrain.org/docs#Using_neuroConstruct_Based_Projects) can also be used to generate NEURON code (including Parallel NEURON) from NeuroML models.

## NEST

NEST is available for download [here](http://www.nest-initiative.org).

NEST is currently supported through conversion of NeuroML models to [PyNN](http://neuralensemble.org/trac/PyNN). See [here](http://www.neuroml.org/pynn).

Greater native support for NEST is planned in [NeuroML v2.0](http:///www.neuroml.org/neuroml2) (see [here](https://github.com/NeuroML/org.neuroml.export/blob/development/src/main/java/org/neuroml/export/nest/NestWriter.java)).

## PSICS

PSICS is available [here](http://www.psics.org).

There is some [native support](http://www.psics.org/neuroml/index.html) for NeuroML in PSICS, but [neuroConstruct](http://www.opensourcebrain.org/docs#Using_neuroConstruct_Based_Projects) can also be used to generate PSICS code from NeuroML models.
