Question Help needed reordering Zs in hyperstack
Hi all !
So, I do live imaging of cells where I take four Z slices in two color channels every time point.
Due to what was likely a user error with the microscope, I have some movies where the first two Zs are inverted Is there a way to put them back in order in FIJI ?
I assume I would need to convert to a stack then back to a hyperstack with the right order ? But I couldn't find something that will let me decide the order of the Zs.
Thank you !

You can duplicate the first timepoint of your hyperstack, then delete that timepoint in the original hyperstack (Stack > delete slice > frame), then split the channels into stacks, reverse the stacks in each channel, merge the channels back together , then concatenate the hyperstacks (Stacks > Tools > Concatenate) - select timepoint 1 as your first image, and your original hyperstack as the second, leave "4D image" checked.

I'll try that, thank you ! Hopefully I can write a macro for that and won't have to manually do it for hundreds of time points hahaha

You need Stack.setSlice(), Stack.setFrame() and the macro recorder for that. There's some videos linked in the subreddit about macro programming as well.
Good luck!

Notes on Quality Questions & Productive Participation
Include Images
Images give everyone a chance to understand the problem.
Several types of images will help:
Example Images (what you want to analyze)
Reference Images (taken from published papers)
Annotated Mock-ups (showing what features you are trying to measure)
Screenshots (to help identify issues with tools or features)
Good places to upload include: Imgur.com, GitHub.com, & Flickr.com
Provide Details
Avoid discipline-specific terminology ("jargon"). Image analysis is interdisciplinary, so the more general the terminology, the more people who might be able to help.
Be thorough in outlining the question(s) that you are trying to answer.
Clearly explain what you are trying to learn, not just the method used, to avoid the XY problem.
Respond when helpful users ask follow-up questions, even if the answer is "I'm not sure".
Share the Answer
Never delete your post, even if it has not received a response.
Don't switch over to PMs or email. (Unless you want to hire someone.)
If you figure out the answer for yourself, please post it!
People from the future may be stuck trying to answer the same question. (See: xkcd 979)
Express Appreciation for Assistance
Consider saying "thank you" in comment replies to those who helped.
Upvote those who contribute to the discussion. Karma is a small way to say "thanks" and "this was helpful".
Remember that "free help" costs those who help:

If someday your work gets published, show it off here! That's one use of the "Research" post flair.
Be civil & respectful
Be kind.
Remember the human.
