Before you start tracing an imported image... |
- Place a slide on the stage.
- Select objective and lens.
- Rotate the microscope's nose piece to select the appropriate objective.
- Select the matching lens from the Lens drop-down menu in the toolbar.
- Optional: If you don't see the tissue, select Acquisition>Live Image.
- Choose a location for the reference point.
- Manual stage: Move the stage until the desired location is within the field of view.
- Motorized stage: Use the joystick to move to the desired location. Using the Joystick
- Click to place the reference point.
- Verify that Neurolucida is registering movement along the Z-axis.
- Display the Z Meter by clicking the Z Meter icon
. - Focus up and down using the focus knob on the joystick (or the focus on the microscope if equipped with an internal Z motor).
- Click Trace>Manual Neuron Tracing.

- Open the image or image stack.
- If the image was acquired with an MBF system, go to step 3; if not, verify that the scaling is correct—This is critical!
Correct scaling means that Neurolucida uses the same scaling (i.e., micron-to-pixel or micron-to-voxel ratio) as the scaling that was used when the image was acquired.
- If scaling is embedded in the image, Neurolucida applies the correct scaling.
- If there is no software lens associated with this scaling, you are prompted to define a lens so that the image is displayed at its real/original size.
- If no embedded scaling is identified:
- Measure an artifact of a known length with Tools>Quick Measure Line to verify that Neurolucida is applying the correct scaling.
- Verify that Neurolucida is registering movement along the Z-axis.
- Display the Z Meter by clicking the Z Meter icon
. - Focus up and down using the mouse wheel or the Page Up/Page Down keys.
- Click Trace>Manual Neuron Tracing.
