Display Preferences: Grid
The Grid is a rectangular overlay that may be useful for:
- Checking the calibration of lenses.
- Dividing a region into fixed areas for further analysis.
The grid is anchored at the reference point and moves along with the tracing as the tracing and stage are moved.
Grid Enabled: Displays a rectangular grid; its size is defined by Grid Spacing.
Bright Grid: Displays grid at maximum brightness. Use when the slide illumination levels are high. The default is medium brightness.
Grid On When Whole File Shown: Displays grid when an aerial viewing mode is selected. Disable this option if the grid display is too dense when using Go To or Where Is.
Show Grid Labels for Each Cell: Displays the coordinates of the grid.
- A0 is the coordinate of the reference point.
- Letters go in alphabetical order to the right of the reference point, and numbers increase below the reference point.
- Grid intersections to the left of the reference point are listed with negative letters.
- Intersections above the reference point are listed with negative numbers.
Grid Spacing: Sets the dimensions of the grid.
- When you change the objective from one magnification to another, the grid changes size accordingly.
- At low magnifications, the grid can become so dense that the entire screen is covered with nothing but grid lines. Neurolucida prevents this by automatically turning off the grid when the spacing between grid lines drops below 4 pixels.
