How to deal with uneven grid?

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:

Changed:
<
<		1) Takea 4x image to use as a map.
>
>		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.
