metbit.ui_picky_peak
Visualization and apps module in metbit 6.5.7.
import metbit.ui_picky_peakClasses
pickie_peak
A class to display and interact with NMR spectral data, enabling users to pick peaks from an interactive plot.
Parameters: - spectra (pd.DataFrame): A DataFrame containing NMR spectral data with rows representing different spectra and columns representing intensity values at each chemical shift (ppm). - ppm (list): A list of ppm values corresponding to the columns in the `spectra` DataFrame.
Methods: - run_ui: Launches a Dash web application with a user interface to visualize NMR spectra, select peaks interactively, and export peak positions.
Example: ```python import pandas as pd spectra = pd.DataFrame(...) # Load or generate spectral data ppm = [...] # Define corresponding ppm values picker = pickie_peak(spectra, ppm) picker.run_ui() ```
Usage: 1. **Plot Visualization**: Displays the spectra using an interactive Plotly graph. 2. **Peak Selection**: Allows users to click on the plot to select peaks, storing their positions. 3. **Export Functionality**: Offers options to export selected peak positions as a CSV file.
