tedana: TE Dependent ANAlysis
About
TE
-de
pendent ana
lysis (tedana
)is a Python library for denoising multi-echo functional magnetic resonance imaging (fMRI) data.
tedana
originally came about as a part of the ME-ICA pipeline, although it has since diverged.
An important distinction is that while the ME-ICA pipeline originally performed both pre-processing and TE-dependent analysis of multi-echo fMRI data,
tedana
now assumes that you’re working with data which has been previously preprocessed.
For a summary of multi-echo fMRI, which is the imaging technique tedana
builds on,
visit Multi-echo fMRI.
For a detailed procedure of how tedana
analyzes the data from multi-echo fMRI,
