This is a very basic technological issue that I have never experienced with CellProfiler before. I am trying to use template that I downloaded straight from your website entitled “Collagen Analysis” on my own images of collagen fibers, but the pipeline will not run. A message says “pipeline did not identify any image sets.” I have attached a screenshot of what my pipeline, image input and warning look like, and my images are clearly inserted. What settings must I change? Thank you!
