Hi Kathrin,
before you execute 'Analyze Particles' you get a dialog with choices. If
you check 'display results' you should get a table of measurements with
one line per particle. What measurements you do get depends on what
boxes are checked in 'Analyze>Set Measurements... .' If you miss any
parameters you can export everything into a spreadsheet program and do
the calculations there.
Another useful feature in 'Analyze Particles' is the dropbox called
'show'. It will get you a drawing of all the particles in the image.
Just change the setting to 'outlines'.
This should get you going if you are using a fairly up to date version
of ImageJ.

As I know these are the points I have to do before using "analyse particles".  If I do this, as a result I get the area percentage of all particles compared to the whole area. But is it possible to get the area percentage of every single particle?
