-Welcome to wristpy, a Python library designed for processing and analyzing wrist-worn accelerometer data. This library provides a set of tools for loading sensor information, calibrating raw accelerometer data, calculating various physical activity metrics, finding non-wear periods, and detecting sleep periods (onset and wakeup times). Additionally, we provide access to other sensor data that may be recorded by the watch, including; temperature, luminosity, capacitive sensing, battery voltage, and all metadata.

 The main processing pipeline of the wristpy module can be described as follows:
 
-- **Data loading**: sensor data is loaded using [`actfast`](https://github.com/childmindresearch/actfast), and a `WatchData` object is created to store all sensor data.

 - **Data calibration**: A post-manufacturer calibration step can be applied, to ensure that the acceleration sensor is measuring 1*g* force during periods of no motion. There are three possible options: `None`, `gradient`, `ggir`.
 - ***Data imputation*** In the special case when dealing with the Actigraph `idle_sleep_mode == enabled`, the gaps in acceleration are filled in after calibration, to avoid biasing the calibration phase.
-- **Metrics Calculation**: Calculates various activity metrics on the calibrated data, namely ENMO (Euclidean norm, minus one), MAD (mean amplitude deviation) <sup>1</sup>, Actigraph activity counts<sup>2</sup>, MIMS (monitor-independent movement summary) unit <sup>3</sup>, and angle-Z (angle of acceleration relative to the *x-y* axis).
-- **Non-wear detection**: We find periods of non-wear based on the acceleration data. Specifically, the standard deviation of the acceleration values in a given time window, along each axis, is used as a threshold to decide `wear` or `not wear`. Additionally, we can use the temperature sensor, when avaia\lable, to augment the acceleration data. This is used in the CTA (combined temperature and acceleration) algorithm <sup>4</sup>, and in the `skdh` DETACH algorithm <sup>5</sup>. Furthermore, ensemble classification of non-wear periods is possible by providing a list (of any length) of non-wear algorithm options.
-- **Sleep Detection**: Using the HDCZ<sup>6</sup> and HSPT<sup>7</sup> algorithms to analyze changes in arm angle we are able to find periods of sleep. We find the sleep onset-wakeup times for all sleep windows detected. Any sleep periods that overlap with detected non-wear times are removed, and any remaining sleep periods shorter than 15 minutes (default value) are removed.
-- **Physical activity levels**: Using the chosen physical activity metric (aggregated into time bins, 5 second default) we compute activity levels into the following categories: [`inactive`, `light`, `moderate`, `vigorous`]. The threshold values can be defined by the user, while the default values are chosen based on the specific activity metric and the values found in the literature  <sup>8-10</sup>.
-- **Data output**: The output results can be saved in `.csv` or `.parquet` data formats, with the run-time configuration parameters saved in a `.json` dictionary.
