Dear Tracy,
I think the easy way would be to run an analysis without doing any
filtering whatsoever. When you select a voxel and plot the adjusted
responses they should correspond to the mean-corrected voxel
timeseries and be exported to the workspace as the 'y' variable.
The only problem is that you will only be able to select voxels
on which spm stores data on in the y.mad file. These are defined
as those that survive some global F-threshold for effects of interest,
which is in turn specified in the defaults and can be easily set to
1.00 for all voxel timeseries to be stored (but will take up lots
of space).
Alternatively I belive the professional way to do it is to
use spm_vol and spm_sample_vol. Try 'help' with these
functions for more details.
Good luck
Afraim
