Hello SPM'ers,
I encountered a small 'problem' with spm_fMRI_design, especially the help
of this function. Using the GUI or some batch you can specify your design
in SCANS or SECONDS. Next, you can specify the duration of your trials.
Although the help of spm_fMRI_design states that these duration must be in
seconds
(line 28 --% length: - support of basis set {seconds} ----)
a simple test suggested that if I specify my design in SCANS these
durations are in SCANS (ie not seconds) and if I specify my design in
SECONDS these durations are indeed in SECONDS like the help suggests.
Did anyone else encountered this as well? Are the durations indeed in
SCANS when I specify my design in SCANS? If this is the case, maybe this
should be changed in the help of the spm_fMRI_design function, to avoid
confusion.
Thanks,
Martijn van den Heuvel
