Data: motion corrected data from one resting state and one task fMRI (Valsalva gives strong signal changes)
Sydney: use data in Z:\Analysis\Paul\DRIFTER\Testing
Software: DRIFTER as in the CSPM/SPM12 files (this has the correction for empty first slices). Use the batch job template on the parent page.
Analysis: 1) run drifter with the following settings, 2) create a couple of VOI for each series, 3) show timetrends of the VOI for each setting in each series
