Notes:
This set of scripts is a work in progress package for simulating T1
spin history effects in 2D EPI timeseries (e.g. functional MRI or
connectivity) data due to fast head motion. It is meant to replace
the slomoco sub-package released recently, by incorporating
additional T1 preparation scripts and a simulator that is
reasonably fast (<1hr for 128x128x31 dataset) and simulates at
1% of the slice thickness. T1 effects are all about out-of-plane
motion, and that is all that is simulated here, by combining this
with SLOMOCO, the goal is to perform a complete correction of
motion effects in BOLD rs-fMRI and fMRI data.
Also included is a new PESTICA filter script and a new physio
estimator script for SLOMOCO output. SLOMOCO estimates nearly
always contain sufficient respiratory noise to isolate respiratory
trace, and sometimes contain sufficient cardiac signature (works
most of the time at 7T but not often at 3T). This script can be
used with SLOMOCO output to produce respiratory traces and
sometimes cardiac traces that could be used similar to PESTICA
estimators and monitored pulse and respiration. Also still a work
in progress.
