Dear SPM fans,
can someone explain to me and if possible guide me to
some literature as to why the onsets need to start at 0
(zero) when entered in SPM?
Also, if the onsets start at zero and are written into
the design matrix, should regressors that I input
manually (not the motion parameters rp_*.txt file) also
start at 0? If they don't then I suppose they won't line
up with the onsets, since both of them are columns in
one matrix.
Cheers,
Glad
