I’m just starting to use Fiji for analyzing my microscopy data. I am trying to utilize the Kalman stack filter (image --> stacks --> Kalman Stack Filter) to reduce the noise in my images. It seems like clicking on the KSF is supposed to open a dialogue box where one can set parameters. Yet, when I click KSF, I get a dialogue asking me to specify a file location. I’m not understanding whether it needs me to locate the KSF plugin, or specify a save location (hopefully I wouldn’t have to do this for every image stack). No one in my lab has run into this problem before, so any help is appreciated! I am running a Mac circa late 2012, OS X El Capitan. Java is up to date.
