fMRI Point Process Avalanches
A Python package for doing point process analyses on fMRI data.
Built at Neurohackweek 2017 by:
(Project directory structure organization via Shablona.)
More Info
As a first pass, we have implemented the threshold-based point process and avalanche detection methods described in the following paper:

Summer of Code Blog Posts
Asier created an early version of this package in 2015 as a participant in the Google Summer of Code program. He documented his work in a few blog posts:
His original code can be found here.
Test Data
To test our code during Neurohackweek, in addition to simulated data with known avalanches, we also used openly shared preprocessed fMRI data from OpenNeuro:
- Dataset (associated with this paper, but the acquisition is described here)
- Analysis
