Python Cortical mapping software for fMRI data

Project description


Build Status

quickflat demo

Pycortex is a software library that allows you to visualize fMRI or other volumetric neuroimaging data on cortical surfaces.


To install the stable release version of pycortex, do the following:

# First, install some required dependencies (if not already installed)
pip install -U setuptools wheel numpy cython
# Install the latest release of pycortex from pip
pip install -U pycortex

If you wish to install the development version of pycortex, you can install it directly from Github.

To do so, replace the second install line above with the following:

# Install development version of pycortex from github
pip install -U git+git://


Pycortex documentation is available at

You can find many examples of pycortex features in the pycortex example gallery.

To build the documentation locally:

# Install required dependencies for the documentation
pip install sphinx_gallery numpydoc
# Move into the docs folder (assuming already in pycortex directory)
cd docs
# Build a local version of the documentation site
make html

After you run the above, you can open docs/_build/html/index.html in a web browser to view the locally built documentation.


Pycortex is best used with IPython.

If you do not already have IPython, you can install it by running:

pip install ipython

To run the pycortex demo, using IPython, run:

$ ipython
In [1]: import cortex
In [2]: cortex.webshow(cortex.Volume.random("S1", "fullhead"))
