Placing and editing markers(3D)

Placing markers

  1. Select a marker type from the list.
  2. Navigate as needed and click in the Tracing window to place markers over the neuronal structures.

To delete the last marker you placed, press CTRL-Z.

To rename marker types, you need to leave the 3D environment and use one of these two methods:

  • Go to File>Preferences>Tracing; find the Markers section and click the Customize button; double-click a name and type a new name.

or

  • Right-click over a marker type in the Markers toolbar and select Rename marker.

When you return to the 3D environment, you'll find the names automatically updated in the list.

Editing markers

With the marker mode active, click the edit button to display the editing options.

To see all the options, select at least one marker:

The minimal display size for a marker is 1px.

  • In Pixels:The size is fixed and the same for all markers; zooming in or out has no effect on the display size of the markers. This is the usual method for displaying markers.
  • In Microns: The size of the markers is the same for all markers and is adjusted as you zoom. The markers are scaled along with the tracing.
  • Intrinsic: The intrinsic size for each marker is defined by the diameter of the circular cursor when the marker was placed; therefore the intrisic value cannot be modified in 3D. Since this size is defined in actual micrometers, the displayed size depends on the zoom level. If you zoom out, you may not see the markers since they are scaled as small as possible. The intrinsic setting allows you to define a different size for each marker.
  1. Click Select All to select all the markers OR hold down CTRL and drag the mouse to trace a marquee around a marker in the tracing window.
