Above is what I tried. However it throws an error, I think it would be due to the creation of a new image, and that KNIME doesn't know how to handle this.
Now I tried this, to avoid having to duplicate the image. However I get an error:
ERROR ImageJ Macro 0:67 Error in row Row0: Interval must fit into src in SubsetViews.subsetView(...)
ERROR ImageJ Macro 0:67 Execute failed: java.lang.IllegalArgumentException: Interval must fit into src in SubsetViews.subsetView(...)
I thought this means that my rectangle doesnt fit within the image, but it does exactly. My image is sized 4320*3240.
Hi Luuklag, take a look at the attached workflow. It shows how you can cut out a region of interest from a series of images using the interactive anotator.
Sounds like a good solution, but how do I enter the four numbers that define my area. I have no clue about flow variables, and haven't been able to find any decent tutorial about it either.
Thanks, this works like a charm. I'll edit it a bit however, as my ROI is always the same size and place in the image, therefore I think it would be best to keep those labelings as a saved image, and keep them constant as to improve computation time.
