Use Threshold? is selected by default. If you deselect it, the
threshold slider will do nothing and you will get NO
thresholding at all.
Thr = OLay ? sets the
Thr sub-brick to be the same as the
OLay sub-brick. This is useful for looking at full F-stats or
Thr = Olay+1 ? (note to staff: capitalization is wrong here)
Thr sub-brick to be the next sub-brick after the
OLay that is selected. This is useful for t-tests or anything
with a coefficient and a T-stat.
AutoThreshold: the threshold is selected as
0.5*median of the
upper 65% of the positive values in the volume. If it’s a statistic,
then the threshold is the square root of the value that
corresponds to 0.001 and that
Set threshold pops up a dialog allowing you to enter a
number directly. It will modify the
10^ selection to match the
number you enter. If you enter a negative number, the threshold
slider will flash and there will be an annoying beep tone.
Set p-value and
Set q-value will give you the same dialog
boxes as shown above with the scrolling actions.
Set p=0.001 does what it says… Just quicker than messing with
Sign gives you 3 options. The default is
Pos & Neg.
Pos only hides all of the negative values, but keeps the color
scale unchanged. This differs from the
Pos? button in that the
Pos? button will rescale the colors so that
~0.0 is the bottom
of the color bar.
Neg only hides all of the positive values but
keeps the color scale unchanged. These choices interact with the
Pos? button. So if you have
Pos? selected, then choose
Neg only you will hide everything.
Pos? selected with
Pos only or
Pos & Neg is the same as
