The Python package skbold offers a set of tools and utilities for
machine learning analyses of functional MRI (BOLD-fMRI) data.
Instead of (largely) reinventing the wheel, this package builds upon an
existing machine learning framework in Python: scikit-learn.
The modules of skbold are applicable in several 'stages' of
typical pattern analyses (see image below), including pattern estimation,
data representation, pattern preprocessing, feature selection/extraction,
and model evaluation/feature visualization.
Please see skbold's ReadTheDocs page for more info on how to use skbold!
Although the package is very much in development, it can be installed using pip:
$ pip install skbold
However, the pip-version is likely behind compared to the code on Github, so to get the most up to date version, use git:
$ pip install git+https://github.com/lukassnoek/skbold.git@master
Skbold is largely Python-only (both Python2.7 and Python3) and is built around the "PyData" stack, including:
- Numpy
- Scipy
- Pandas
- Scikit-learn
And it uses the awesome nibabel package
for reading/writing nifti-files. Also, skbold uses FSL
(primarily the FLIRT and applywarp functions) to transform files from functional
(native) to standard (here: MNI152 2mm) space. These FSL-calls are embedded in the
convert2epi and convert2mni functions, so avoid this functionality if
you don't have a working FSL installation.
This package is being develop by Lukas Snoek from the University of Amsterdam with contributions from Steven Miletic and help from Joost van Amersfoort.
