There is an example of a Random Effects Analysis on the SPM
Data page at:
http://www.fil.ion.ucl.ac.uk/spm/data/#SPM00Multi
If you just download the README file that will list
all the steps. In fact, its quite simple.
Usually (if you have one population and one effect) you
just make one contrast image per subject (from 'first-level'
analyses) and the do a one-sample t-test on these images.
Best wishes,
Will.
