It seems to me that you first have to be sure that each z-slice is independent --that you are not detecting fluorescence from one slice in another.--

Hi all,
I have a user who wants to measure the volume, not intensity, of the FISH-labeled region in a z-series.

Any issues with the following proposal, besides using a histogram to get pixel numbers?

1. Threshold the FISH signals for control and experimental Z-Series
images with identical conditions.
2. Create a histogram for each thresholded image and use total pixel number as
the FISH signal volume.

Thanks,
C
