How to Use the Brain Volume Explorer
Invoke the volume explorer by clicking on a brain volume icon in the left column of the table
of available brain volumes. This will open a new BRAIN VOLUME EXPLORER window.
In the middle of the window is an image of a subsection of the volume. This is the Current View.
The X, Y, and Z position indicators show the position of the lower-left corner
of the current view relative to the lower-left corner of the start of the volume.
Go to a new position in the volume by typing in new X, Y, and Z values and then clicking
on Load View. You may also use Load View to return to the last view after playing a flipbook.
 |
The brain volume icon is used to indicate network activity. It rotates while a new view is loading from the server.
When recording, refrain from view requests while the brain volume icon is rotating.
To abort a view request and stop the icon from rotating, simply click on it. |
 |
Use the movement arrows to shift the current view a fixed increment in a
particular direction. X and Y icons shift 0.5 microns in the plane of section.
The Z icons shift 1 section thickness in depth. |
The Flipbook Recorder
allows you to record a sequence of views and play them back without waiting for network transfers.
 |
Click on the record button to begin recording a sequence of views.
Click the button again to turn off recording.
You can resume recording at the end of the sequence by turning recording on again. |
 |
Flip to the next section in the recorded sequence. This button is grayed when no sequence is recorded. |
 |
Click on the play button to animate a recorded sequence. The animation will swing
continuously back and forth through the sequence until the button is clicked again.
This button is grayed when no sequence is recorded. |
 |
Flip to the previous section in the recorded sequence. This button is grayed when no sequence is recorded. |
 |
Delete the recorded sequence from memory. This button is grayed when no sequence is recorded. |
 |
Use this button to enter a new value for the delay between each view of the sequence. The
initial delay value is 0.5 seconds. Set it to a smaller value for faster play back. |
Additional Navigation Tips:
- Do not use your browser's BACK item to return to previous views. Your browser has no
knowledge of navigation within the volume.
- Do not use RELOAD/REFRESH to update the page. This will return you to the default settings
(the start point) for the volume.
- Allow time for views to load. When fully zoomed out, view access time may take several seconds.
- When recording, allow a view to load completely before proceeding to next view. Otherwise,
the view may not be properly recorded.
- To flicker between sections, record an animation sequence of the two images and play it.
