Greetings,  I am new to this list.  We have 16-bit images giving  
elemental maps of soil particles from EPMA (electron probe micro  
analysis).  I've been trying out ImageJ for awhile and can do the  
basics of importing, thresholding and determining areas.  I need to  
get a little more advanced such as calculating the area of a certain  
range in ratios of elements (e.g. Si:Al and Si:Al:Ca) from two or  
three maps, but I'm stuck.  It seems as if someone should have done  
this before.  Does anyone know a good resource, i.e. tutorial or link  
with info on this type of application?  I've searched through the  
plugin list but haven't found anything yet.

thanks very much,
