PESTICA fMRI Physio Detection/Correction

Do you have 3D+time EPI data (BOLD or perfusion) but no usable physio signals for pulse and respiration? Are you concerned about the effect of physio noise on your data but don't know what to do but regress data-derived signals that mix unknown functional signal with possible physio noise signal? This is for you. This distribution includes a tool (Physiologic EStimation by Temporal ICA or PESTICA) to detect physiologic signals _from the data itself_! These signals are equivalent to a parallel monitored pulse signal and a respiratory chest-bellows signal.
Are you concerned about the number of regressors you're incorporating once you add 5th order RETROICOR (20 more regressors!)? 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. These tools will allow you to correct your data for physiologic noise with what you currently have.
