Jupyter Reports with Papermill

Parameterized Notebooks

import papermill as pm

# Execute notebook with parameters
pm.execute_notebook(
    'analysis_template.ipynb',
    'output_report.ipynb',
    parameters={
        'input_file': 'data/counts.csv',
        'condition_col': 'treatment',
        'fdr_threshold': 0.05
    }
)

Creating Parameterized Templates

Mark a cell with the parameters tag in Jupyter:

# Parameters (tag this cell as "parameters")
input_file = 'default.csv'
output_dir = 'results/'
fdr_threshold = 0.05

Batch Processing

import papermill as pm
from pathlib import Path

samples = ['sample1', 'sample2', 'sample3']

for sample in samples:
    pm.execute_notebook(
        'qc_template.ipynb',
        f'reports/{sample}_qc.ipynb',
        parameters={'sample_id': sample}
    )

Converting to HTML/PDF

# Single notebook
jupyter nbconvert --to html report.ipynb

# With execution
jupyter nbconvert --execute --to html report.ipynb

# PDF (requires pandoc + LaTeX)
jupyter nbconvert --to pdf report.ipynb

Best Practices

• Keep analysis code in cells, explanatory text in markdown
• Use parameters for all configurable values
• Include version information and timestamps
• Clear outputs before committing to version control
