jswalker,
Pasting your method call in from Nabble (it doesn't get copied to the email
list...), I assume your error message occurs when you run this line:
if RoiManager.moveRoisToOverlay(imp3):
From the API documentation (you already referenced, but for others who
don't know, go to
http://rsb.info.nih.gov/ij/developer/api/, then select
the RoiManager class in lower left pane, and finally find the
moveRoisToOverlay method in right-hand pane), you'll see it is an instance
method, *not* a static method. That means you need to call it with an
instance of RoiManager, not the class name as you called it. Something
more like
r = RoiManager.getInstance() # getInstance() *is* a static method
r.moveRoisToOverlay(imp3) # now you have 2 arguments--"r", the
RoiManager instance and "imp3".
Your if statement can then be something like
if r is not None:
I just took your snippets of code, and suggested other snippets without
seeing the whole thing, so I hope this works, and gets you started.
