Hit OK for Data!Įvery particle has a row. Set “Show:” to “Nothing” (unless you want to visually see the counted objects in which case Outlines is quite nice), and make sure to Check “Display Results”. It makes no difference as we’ve already refined the mask to these parameters. You can leave the size at 20-2000 or change it to 0-Infinity. We’re now ready to run and measure the particles. “Display Label” is also nice to have a record of the image that you’re measuring. In order to select which parameters the “Analyze Particles” tool will return, run and check “Area”, “Shape Descriptors” and “Fit Ellipse”. Now you can run to separate the low-overlap particles. Hit OK and you’ll have your refined mask (you may want to run to flip the image back to white on black so Fiji doesn’t get confused.) Uncheck the options and make sure the “Show:” box is set to “Masks”. Here the 20nm lower limit is to remove any specks of noise in the image. To do that, use the magic wand tool and select the smallest of the big blobs that you want to remove and hit ‘m’ to measure the area.Īrmed with that information, run and restrict the size of the particles between 20-2000. ![]() But first we need an estimate of how big the big blobs are. To get around this problem, before we run a Watershed filter to separate low-overlap particles, we’re going to filter out the large blobs using the Analyze Particles tool at. This works well when objects are only touching slightly (see below for an example).īefore (left) and after (right) Watershed processing Normally when we have particles touching, we can (and will) use a Watershed algorithm to split touching objects. The second point is a little more complicated.
