Automated Fiber Quantification in Python (pyAFQ)

pyAFQ is an open-source software tool for the analysis of brain white matter in diffusion MRI measurements. It implements a complete and automated data processing pipeline for tractometry, from raw DTI data to white matter tract identification , as well as quantification of tissue properties along the length of the major long-range brain white matter connections.

Note

Tractography is concerned with the visualization and mapping of white matter tracts in the brain, while tractometry involves the quantitative analysis of the structural properties of these tracts. Both techniques are valuable in understanding the brain’s connectivity and can provide insights into various neurological conditions and cognitive processes. More information can be found in the Explanations page.
