import metbit.calibrate

Functions

calibrate(X, ppm, calib_type='tsp', custom_range=None)

Calibrate chemical shifts in NMR spectra using known reference peaks.

Parameters: X (np.ndarray or pd.DataFrame): NMR data matrix (rows: spectra, columns: PPM positions). ppm (np.ndarray): 1D array of chemical shift values. calib_type (str): 'tsp', 'glucose', 'alanine', or 'custom'. custom_range (tuple): Optional (start, end) PPM range for custom calibration.

Returns: pd.DataFrame: Calibrated NMR data matrix.
