Bring section under focus in StereoInvestigator
Acquisition → Acquire Image
- Click on the image, but not on the section
Image → Add Scalebar
- Set to 100 microns
- Apply Scalebar
To get to the next section revert back to Live Image and Select New Data File
Open Image in ImageJ
Open a second image
Both Images:
- Image → Type → 8-bit
One Image:
- Analyze → Set Scale
- 70 pixels → 100 μm
- Process → Subtract Background
- 50 pixels rolling ball radius
- Check Light Background
- Use color picker to pick a color closest to white
- Use pencil to whiteout all dark areas not part of the spinal section or are “spots” on the section
- Image → Adjust → Brightness and Contrast
- Adjust min/max bars until microglia are clearly contrasting the background
- Compare with other 8 bit image
- Image → Adjust → Threshold
- Adjust Threshold value until microglia are selected and as much background is removed as possible
- Use zoom tool to compare with 8-bit image
- Analyze→ Analyze Particles
- Select Summarize and DIsplay Measurement
- Mark down: Count, Total Area, and Average Size
