Peak Explorer

Peak Explorer is a Streamlit app for exploring MINT peak output interactively. It lets you inspect the distribution of peak area values for a selected compound and compare chromatograms across samples in the same view.

Features

• Upload .csv or .parquet MINT output files
• Fall back to the bundled results_backup.csv example dataset
• Select a compound and compare one or more samples
• View peak area distribution alongside chromatogram traces
• Preview the loaded dataset directly in the app

Required columns

The app expects these columns:

• peak_label
• ms_file_label
• peak_area
• peak_area_top3
• peak_max
• scan_time
• intensity

Run locally

Install dependencies:

pip install -r requirements.txt

Start the app:

streamlit run run.py

Notes

• scan_time and intensity are expected to contain list-like values for chromatogram plotting.
• If no file is uploaded, the app loads results_backup.csv automatically.
