Dear Johannes and Jay, thank you both for the reply, links and the latex documentation. Yes indeed I did had instantiated ImageJ multiple times..
Now I just tried using one of the tutorial examples: image-tutorials/add-two-datasets So I created a new maven project, added the pom file from this link: https://github.com/imagej/imagej-tutorials/blob/master/add-two-datasets/pom.xml and the java file from: https://github.com/imagej/imagej-tutorials/blob/master/intro-to-imagej-api/src/main/java/IntroToImageJAPI.java and tried to run the application, but I got the following error: java.lang.NoClassDefFoundError: net/imagej/updater/UploaderService Is there anything I'm missing?
