Hi - I set my Mac up with the exact same versions of 32-bit OS,
AIJ, IJ, and Java that you reported, and I have not been able to
recreate the problem where no apertures are being placed when
left-clicking on alignment stars. I can duplicate the "Error reading
apertures file" if I remove my preferences file, start AIJ, and
click on the "draw all stored apertures in overlay" button before
defining any aperture locations. This is not a bug since no
apertures have been defined before clicking the button to display
apertures. However, the error message is incorrect, and I will fix
that to say "No apertures stored".
Back to the original problem. Since this is apparently not an
installation or platform dependent issue, there are only a couple of
other things I can think of to move forward. The easiest is to first
remove or name your AIJ preferences file. First close AIJ
completely. Then remove/rename the file. On a Mac, the file is
located at:
<username>/Library/Preferences/AIJ_Prefs.txt
Now restart AIJ and try to align the images again. When you close
AIJ, a new prefs file will be generated with the default values.
If that doesn't seem to fix the problem, there must being something
in the image header that is causing a problem. Are the image files
small enough to email (even one at a time if needed)? If so, you can
send them directly to me at karen dot collins at insightbb dot com.
I will of course not share them and will destroy them as soon as we
figure out what is wrong.
A couple of additional questions that might help give a clue before
sending the images: what is the file format of the images you are
opening? how large are the images? I understand you said there are 3
images in the stack.

Hi - I did the update and checked About to make sure
it was running 2.1.3. But no change in behavior, it still does not
show any apertures. For what it is worth, there is a "draw all
stored apertures in overlay" button in the image window. When I
click on it there is an error message "Error reading aperatures
file".
