PESTICA & SLOMOCO: physio and motion correction tools
PESTICA detects the pulse and the breathing cycles _from the data itself_, equivalent to a parallel monitored pulse signal and a respiratory chest-bellows signal. One can use parallel monitored or PESTICA-monitored pulse and respiration for correction using the model-based corrections RETROICOR or IRF-RETROICOR.
The other half of PESTICA is an adaptive physiologic noise removal tool (Impulse Response Function or IRF-RETROICOR) that zooms in on noise with only 6 regressors, getting all the noise that 5th order RETROICOR gets (using 20 regressors). These tools will allow you to correct your data for physiologic noise with what you currently have.
