Dear John,

As I recall, the data underwent the following processing steps:
(1) Realignment/reslicing of T2* timeseries to the first image (no
correction for spin excitation history)
(2) Coregistration of T1 structural to T2* timeseries
(3) Normalisation parameters generated from T1 image (to T1 template) and
applied to T2* timeseries
(4) Smoothing with 6mm isotropic kernel
With the recent availability of the EPI template for normalisation, and
the imminent public release of SPM99, I anticipate an updated
training dataset will be made available with further documentation in the
near future.
Best wishes,
Geraint Rees
