Display Preferences: Markers

Most of these options are also available when you right-click the Marker toolbar.

The minimal display size for a marker is 1px.

In Pixels: Changing the lens 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 depends on the lens selected. The markers are scaled along with the tracing. You may not see the markers since they are scaled as small as possible.
Intrinsic: The intrinsic size for each marker is defined by the diameter of the circular cursor when the marker was traced. Since this size is defined in actual micron values, the displayed size depends on the lens selected. If a low-power lens is selected, you may not see the markers since they are scaled as small as possible. The intrinsic setting allows each individual marker to be displayed at a different size.

Marker Name: Each marker is originally assigned a default name. To assign a different name to a marker, highlight the current name and type in the new one. The name of the marker is used in all subsequent reports. For example, if three markers are renamed to neuron, glial cell and blood vessel, instead of seeing the number of Marker 1, Marker 2, etc. in a report, the report states the number of neurons, glial cells, blood vessels, etc.
Hidden: Hides all markers of a given type (see Hidden Objects).
All Visible: All hidden markers are displayed.
None Visible : All markers are hidden.
Set Color: Select a marker symbol before using this button. Changes the color used to display the markers of the selected type.
Default Colors: Restores the default colors for each marker type.
