Kathy,

I do exactly what I believe you are considering. I measure the average
intensity of many cells (neurons) over time in a stack of images. As Bob
suggested do the following:

- open ROI Manager
- you'll probably use the ellipitcal ROI so click on that on the main menu
of imageJ and select your first cell
- press 't' (or click "Add" on the ROI Manager)
- then, and this is important, click Show All on the ROI Manager
- if you want the same size ROI on all cells its best to move the pointer to
the centre of your first ROI and drag to a new cell - again press 't'.
repeat until all cells selected. do not forget to press 't' after each cell
- in doing this you will see a list of all ROIs appear in the ROI Manager
- to save all of your ROIs click "Save" in the ROI Manager - be sure not to
select any of the ROIs in the list because only those selected will be
saved. If no ROIs are selected in the list then ALL will be saved in a zip
file.
- I use Time series Analyzer to calculate all average intensities in the
image stack

hope this helps.
