I have loaded images through load sequence.
Placed apertures...and when I select target, AIJ selects the comps automatically
when I hit enter, nothing happens..?? how do I get AIJ to do the photometry?
That's the usual operation. Which options do you have set on the Multi-Aperture set-up panel? Can you include a screen grab of your setup panel with your next post?
Your Multi-Aperture set-up panel is indicating only one image in the image display (i.e. there are no starting slice and ending slice sliders at the top). You can confirm this by looking at the image display. If you do not see an image selector slider under the image, then you only have one image open. All of your images need to be loaded into a common image stack for automatic Multi-aperture analysis. You can do that by either dragging an image folder from the Windows File Explorer and dropping it onto the AIJ Toolbar, or go to Toolbar > File > Import > Image Sequence to load a stack of images.
I see now that you used Import > Image Sequence. It is possible that the file filtering settings may have been wrong. Look at the number next to "Matched files:". It should show a number larger than 1 to load more than one file.
