4D Data Display: Frame Selection


When data of more than three dimensions is loaded into rview for example:

spectroscopy
Example SPECTROSCOPY dataset with multiple frames


Each frame is treated as being in registration within the time series.
By default rview simply displays frame 0.
Other frames can be selected by using the frame select Tool from the Reference or Floating image menus...

This displays the frame tool:

frameselector


This tools allows the selection of the the frame being displayed for the selected 'Image' data set:
Note: Image 0 is the reference Image, 1 is the Image A, 2 is Image B etc....
The Frame control selects the frame (ranging over those that are present in the selected image dataset).
Select 'Apply' to update the display,
OR: select 'Auto Update' to allow the frame control to update the display automatically when it is changed
 (allowing interactive stepping through the available frames).

Pressing the UP and Down keys when mouse pointer is clicked inside the
frame control window will step forward and back by one frame and update
the main rview window.

The traces show the time series of values at the nearest spatial voxel location at:
White: Under the mouse cursor when it is in the rview main window)
Cyan: At the current focus of rview (under the central cross hair)

This allows evaluation of how the temporal sequences vary over the image volume,
by moving the cursor over the image space.

The vertical BLUE line on the trace indicates the current displayed frame.
Clicking on the trace moves the selected frame to this location.
(when Auto Update is selected, this allows the user to interactively pan through the time series)

The range of the vertical scale on the trace is controlled by the Maximum and Minimum controls on the Colour Map Control

Note: if the data has only one frame, this tool will not be displayed (check Scan Info for number of frames in dimension 4).
