Fig. 9.6
Representation of CNV recorded on participant 4 during steps 2 (
solid curve
) and 5
(
dotted curve
). The
solid vertical lines
correspond to warning signals (S1: beep, S2: square). This
participant is kept because the
solid curve
is mainly below the
dotted curve
between T1 and T2
(framed by the
dotted vertical lines
)

Fig. 9.7
Representation of CNV recorded on participant 9 during steps 2 (
solid curve
) and 5
(
dotted curve
). The
solid vertical lines
correspond to warning signals (S1: beep, S2: square). This
participant is rejected because the
solid curve
is mainly above the
dotted curve
between T1 and T2
(framed by the
dotted vertical lines
)
and the
x
-axis is calculated between T1 and T2 (section framed by the dotted
vertical lines). A participant is kept if the area calculated with the CNV recorded in
step 5 is lower than the area calculated with the CNV recorded in step 2. To
facilitate this validation step an allow a visual inspection of the curves, a graphical
user interface was created. This interface is given in Fig.
9.8
. Using this interface,
