NMR: reading TopSpin files (plugin)

This example shows how to read Bruker TopSpin NMR files using the optional spectrochempy-nmr plugin.

Requires the official spectrochempy-nmr plugin. Install with: pip install spectrochempy[nmr].

import spectrochempy as scp

read_topspin is registered under the scp.nmr plugin namespace. The top-level scp.read_topspin alias is kept for compatibility.

ds = scp.nmr.read_topspin(
    scp.preferences.datadir / "nmrdata" / "bruker" / "tests" / "nmr" / "topspin_1d",
    expno=1,
    remove_digital_filter=True,
)

print(f"Loaded dataset: {ds}")
print(f"Shape: {ds.shape}")

Traceback (most recent call last):
  File "/home/runner/work/spectrochempy/spectrochempy/build/~gallery_examples/processing/nmr/plot_read_nmr_topspin.py", line 33, in <module>
    print(f"Shape: {ds.shape}")
                    ^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'shape'

Plot the spectrum:

_ = ds.plot()

If the plugin is not installed, the function or method raises a MissingPluginError with installation instructions.
