Registering uneven Z stacks with each other

Jason Miller
Hi all-

I am brand new to ImageJ/Fiji, but have spent a little bit of time
exploring the registration plugins available. I'm not sure if I have yet
found what I need for the following problem:

I have Z stacks obtained over time. Each Z-stack does not need
registration, but I do need to register the Z-stack from T=1 with the Z
stack from T=2, and the Z stack from T=2 with Z stack from T=3, and so on.
Because I am obtaining these Z stacks over long periods of time in an
automated fashion, the Z-stacks are not 100% aligned with each other, but
they are pretty close. Each Z stack will start at a slightly different
focal plane, and there is a small amount of X-Y misalignment as well.

I had tried MultiStackReg, which certainly will align one Z-stack with
another, but it doesn't consider different focal planes - it aligns slice 1
from one stack with slice 1 from the other stack.

Is there a plugin that can handle the task above? If so, can it handle very
large files (i.e. feeding in a large stitched Z-stack grid from T=1 to
align with a large stitched Z-stack grid from T=2)?

Thanks so much for your help!
-Jason Miller

Hi Jason,

Correct3D drift was written to register a series of Z-stacks in a time-lapse and I think will address the problem you describe.

There is also a JoVE article describing its use

Best wishes
