====== AFNI GUI ======
[[:tools:afni]]'s Graphical User Interface has a deep feature set.

===== Slider ======
You can slide between overlay and underlay. Enable this mode by pushing ''3'' or ''4'' with an image window focused.

===== Graph View =====
For underlays with a time dimension (multiple values), the "graph view" can be used to visualize values at each time. Push ''v'' on the graph window to auto-scroll through time points (like a **v**ideo)

===== p-value =====

Middle click on the p-value to specify a numeric value for thresholding. No need for the fine mouse motor skills to set the threshold slider perfect.
