1) take a Z-‐stack between a defined Z range
2) auto focus each image or every so often
3) use a focus surface
4) manually take images in focus at select areas.
Focus surface feature
Focus surface feature is in XYZ Overview tab
Workflow:
1) Take a 4x image to use as a map.
2) Change to the 50X and manually select 2 dozen or so points randomly to manually find the correct Z-‐height. Use course focus ~2 turns to get in focus, then use stage for fine focus.
3) After enough points are selected you can calculate a focus surface. Use those manually entered XYZ points to define the focus surface and define an area to take a large image. In the ND acquisition menu: the manually entered points will form a green line for z-‐height and calculate an orange line that it'll use as the z-‐height to capture an image.
4) Take a large image in both BF and GFP using the focus surface.
Examples
20X
42 images stitched together with 15% overlap
Area: ~1.7mm x 1.7mm
Time: SF-‐5min SF&SBS-‐7min
40X
154 images stitched together with 15% overlap
Area: ~1.7mm x 1.8mm
Time: SF-‐10min SF&SBS-‐20min
50X
180 images stitched together with 15% overlap
Area: ~1.5mm x 1.6mm
Time: SF-‐18min SF&SBS-‐25min
