Python utilities for NeuroML
Project description
pyNeuroML
A single package in Python unifying scripts and modules for reading, writing, simulating and analysing NeuroML2/LEMS models.
Builds on: libNeuroML & PyLEMS and wraps functionality from jNeuroML.
Installation
Dependencies
pyNeuroML relies on additional software to carry out its functions:
- Java Runtime environment (JRE)
- dot (from Graphviz)
- lxml
On most Linux systems, these can be installed using the default package manager. On Ubuntu based distributions:
sudo apt-get install python-lxml graphviz openjdk-11-jdk
Pip
pyNeuroML can be installed with pip (preferably in a virtual environment):
pip install pyneuroml
Fedora
The NeuroFedora community initiative provides pyNeuroML for use on the Fedora Linux Distribution. Fedora users can install pyNeuroML using the following commands:
sudo dnf copr enable @neurofedora/neurofedora-extra
sudo dnf install python3-pyneuroml
This will also pull in all the necessary dependencies (Java, lxml, graphviz). Please see the project documentation for more information.
Installation from source
Clone the repository:
git clone https://github.com/NeuroML/pyNeuroML.git
cd pyNeuroML
It should be possible to install pyNeuroML using just:
sudo pip install .
You may have to install lxml and the development version of libNeuroML manually:
apt-get install python-lxml
cd ..
git clone https://github.com/NeuralEnsemble/libNeuroML.git
cd libNeuroML
git checkout development
sudo python setup.py install
Current/planned features
1) Single Python package for NeuroML2/LEMS
One Python package which can be installed using pip & a user has everything they need to work with NeuroML2/LEMS files:
- libNeuroML
- PyLEMS
- A bundled version of jNeuroML which can be used to run simulations
2) Run models using jNeuroML or PyLEMS
Ability to run NeuroML2/LEMS models using jLEMS/jNeuroML (with bundled jar) or PyLEMS (todo...)
Uses similar command line interface to jNeuroML, i.e. based on jnml
Try:
pynml -h
to list current options.
3) Access to export & import options of jNeuroML
All export & import options of jNeuroML available through easy command line interface (see here for progress) & through Python methods.
Example of export of NeuroML2/LEMS to NEURON and execution of generated code using single method is here.
4) Helper Python scripts
Lots of helper scripts for commonly used functions, e.g. generating a firing frequency vs injected current plot, generating a LEMS file for use with a NeuroML2 file,
5) Analysis of ion channels
Generation of plots of activation rates for ion channels from NeuroML2 channel file (example):
pynml-channelanalysis NaConductance.channel.nml
Generation of plots of activation rates for ion channels from NEURON mod file (example):
pynml-modchananalysis NaConductance -modFile NaConductance.mod
See here for more.
6) Home for existing functionality distributed in various places
Incorporate ChannelML2NeuroML2beta.xsl for updating ChannelML (coming soon...)
7) NEURON to NeuroML2
Scripts for converting NEURON to NeuroML2
-
Export morphologies (plus channels, soon). See here.
-
mod files - make best guess at initial NeuroML2 form (todo)
8) Export of images/movies from cell/networks
Files can be generated for POV-Ray which can be used to generate high resolution images and even sequences of images for creating movies. try:
pynml-povray -h
9) Tuning cell models in NeuroML 2
Builds on Neurotune and pyelectro. See here for example.
9) Planned functionality
Built in viewer of cells in 3D? Mayavi? More closely tied to PyNN?
