         ### Tips:
-        - Start with a threshold around 100 and adjust based on your staining
+        - Start with a threshold around 200 and adjust based on your staining
         - Dead cells typically have higher blue intensity due to trypan blue uptake
         - The threshold is applied in real-time without re-running segmentation
