Communicate clearly about Jupyter notebook cells without confusing the user.
What Failed
Referring to cells by number (e.g., "Cell 9", "Cell 12")
Cell numbers are NOT visible in Jupyter notebooks
Cell numbers change when cells are added/deleted
User has no way to know which cell you mean
What Works
Refer to cells by identifiable characteristics:
Section header: "the cell under '## Load Data'"
First line of code: "the cell starting with sc.read_h5ad(...)"
Purpose: "the normalization cell", "the plotting cell"
Variable defined: "the cell that creates protein_shared"
Function defined: "the cell with def detection_aware_normalize"
Examples
Bad
"Update Cell 9"
"The error is in Cell 12"
"Cells 10-12 need changes"
Good
"Update the normalization cell (starts with # Normalize shared features)"
"The error is in the visualization cell that plots histograms"
"The cells between 'Load Data' and 'Run Integration' need changes"
Trigger
When discussing or modifying Jupyter notebook cells.
