intan.processing package

Signal processing, filtering, feature extraction, and metrics utilities for EMG data.

intan.processing._metrics_utils

Utilities for loading gesture metrics and creating gesture-label mappings.

This module: - Loads EMG trial classification metadata from CSV or TXT - Parses gesture names into integer class mappings - Provides helper functions for checking or retrieving metrics files

Used in training/testing pipelines that require alignment between gesture labels and EMG signal segments.

load_metrics_data(metrics_filepath, verbose=True)

Loads the metrics data from the specified file path and returns the data along with the gesture mapping.

Parameters:

• metrics_filepath (str) – The path to the metrics data file.

• verbose (bool) – Whether to print the loaded data and gesture mapping.

Returns:

A tuple containing the metrics data as a pandas DataFrame and the gesture mapping as a dictionary.

Return type:

tuple

get_metrics_file(metrics_filepath, verbose=False)

Checks if the metrics file exists at the specified path. If it does, loads the data and returns it.

Parameters:

• metrics_filepath (str) – The path to the metrics data file.

• verbose (bool) – Whether to print the loaded data.

Returns:

The loaded metrics data as a pandas DataFrame.

Return type:

pd.DataFrame
