Introduction to fMRI Analysis in Python

Background

This is one sub-module within the Neuroimaging cirriculum. Visit the link to view all the modules associated with the Neuroimaging Carpentries program.

fMRI Analysis in Python is a programme developed to facilitate reproducibility in functional neuroimaging analyses. Python is emerging as a standard language of data analysis, visualization, and workflow building. More recently, it has rapidly been adopted by the neuroimaging community as a means of developing powerful open-source tools in favour of historically used opaque software such as AFNI, FSL and SPM. In addition, the barrier to entry to Python is low - meaning that you as the user can easily develop your own packages and contribute to the open-source codebase of neuroimaging!

The fMRI Analysis in Python is a workshop series started up via a collaboration between researchers and staff at the Centre for Addiction and Mental Health (Toronto, ON), the University of Western Ontario (London, Ontario), and McGill University (Montreal, Quebec).

About the lesson

This lesson covers fMRI imaging analysis from the basic steps of preprocessing and data cleaning, to running an analysis, to exploring connectivity patterns in the brain.
