Hello,
     I have a question that I cannot find information for on the  
website.  I have an image which has a background that I want to get  
rid of, but it's an abnormal background.  I also have an image of just  
the background.  Is there any way to use the image of the background  
to subtract the background from the original image using imagej?  I  
see a plugin that allows the program to figure out the background and  
subtract it from what it thinks the background is, but I can't find  
anything for if you know the background already.
Thank you,
Brittany Oliva
