You just need to get all of the con* images into a single 4d file,
which should be fairly easy using fslmerge. I believe fslmerge does
file globbing (i.e. using the *), so if all of your first-level
analyses were in the same top folder, you could run something like:
fslmerge -t allcon0001images */con_0001
which would give you a single 4d file called "allcon0001images",
containing one con_0001 volume for each subject. (As with most FSL
functions, you can type "fslmerge" without any arguments to see the
usage/help for the function.)
Hope this helps!
Best regards,
Jonathan
