Hi Chris,
Thanks for the reply.
Yes, I am doing fMRI.
I am aware that I need to do a second level analysis... but I want to
compare two groups at the second level, rather than simply running the
standard second level analysis. Looking at previous papers and their
methods sections has not really helped as they don't report the specifics
of how to set this up in SPM. I can't find an example in the manual or any
hints in the various help options and was hoping someone may give me a
little more insight into how I may set it up.
Thanks again,
Lorelei
