I sent an email some time ago (see below) regarding one functional run
of an fMRI paradigm. Steve Smith replied by saying that I could go
straight to ME cross-subject analysis at the second level. Can I just
confirm that the data that go into this analysis come from the
reg_standard/stats directory (which I have for each subject)?
Also, can somebody point me to a link/previous thread detailing how one
can still perform a Fixed Effects analysis when you have only one run?
Thanks,
Liam.
Hi - only having a single run per subject is actually probably the most
common design and in this case you can go straight to ME cross-subject
analysis at the second level.
