Physiological noise correction¶

There are a number of toolboxes available implementing variants of RETROICOR to correct for physiological noise using physiological recordings (respiratory, cardiac, ...):

TAPAS PhysIO Toolbox - integrated with SPM Batch Editor
PhLEM Toolbox, see also 1
DRIFTER Toolbox - actually not RETROICOR, but a nonlinear Bayesian model of physiological noise
3dretroicor
See also some direct implementations of the RETROICOR algorithm in MATLAB:
