Hi @bnsreenu,
This is my first time analysing bioimages and I am trying out different models but started with STARdist. This is IF image and I want to perform nuclei segmentation on DAPI file. I was able to follow the tutorial and basically trying to run the notebook on my image with default settings and i get this error. Could you please help? Thank you!
labels, polys = model.predict_instances_big(image, axes='YXC', block_size=4096, min_overlap=128, context=128, normalizer=normalizer, n_tiles=(4,4,1))
