Image analysis is often treated as an individual skill—leading to irreproducible pipelines and bias. Sustainable #BioImageAnalysis must be an institutional responsibility: training, automation, standards, and GSP-aligned guidance. Read the full article on LinkedIn: www.linkedin.com/feed/update/...

To Scale, or not to Scale? - When size matters! "Scaling" in image analysis software like #ImageJ & #Fiji may be used ambiguous for different meanings: - specifying pixel sizes - resizing an image - resizing a selection All of those have different use cases and impact. Read more

In the latter case you might be restricted to use red, green and blue as LUTs since that was color separation in cp3 and most likely is also the one in cp4. You also have to specify the cpsam model in the wrapper under --pretrained_model. That's what I figured out so far 🤷‍♂️
