Dear SPM
experts,
I have a question regarding entering my onset times
in my design specification.
I have conducted an event-related fMRI study and have resliced my functional
images to the middle slice, slice 18 (total = 36 slices/image, acquired
ascending, not interleaved). My TR = 2 seconds.
My question is: do I have to correct my onset times
for my reslicing? I have entered my onset times in scans, so if I have to
correct for my slicetiming, this means I start with scan 0.5 and not with scan
0?
Is this correction not made automatically when I
enter as my microtime onset = 18 (and microtime resolution = 36)?
Thanks in advance,
Karolien
