Dynamic EEG Data Viewer: Debugging & Enhancing with Flask and JavaScript
In this video, I walk you through building and debugging a dynamic EEG data viewer using Flask and JavaScript. We tackle real-world challenges like handling metadata, populating dropdowns, and making real-time updates for EEG spectrograms. From refining data fetching to revamping error handling, this session is packed with insights into creating an interactive, user-friendly tool for exploring EEG data.
You'll also learn about the importance of organizing datasets, managing back-end routes, and leveraging tools like Plotly to visualize complex biomedical data. Debugging might be challenging, but every issue brings us closer to a polished application!
