The Area and Time Under and Above the Curve (ATAUC) is a comprehensive analytical tool designed to evaluate ruminal pH measurements collected from indwelling sensors.
Core Functionality
- Processes and analyzes time-series pH data with support for multiple user-defined threshold limits
- Generates detailed visualizations of ruminal pH evolution over time
- Calculates statistical summaries including means, standard deviations, and minimum/maximum values for pH measurements both above and below specified thresholds
- Supports multiple classification variables for grouped analysis
Sensor Management
- Handles data from multiple sensors within the same animal
- Implements advanced smoothing transitions between consecutive sensors
- Adjusts pH values based on configurable time periods (in days) for both preceding and subsequent sensors
- Calculates sensor-specific averages and adjustments to ensure continuous pH monitoring
Analysis Options
- Flexible interpolation methods (linear, spline, hyman)
- Multiple spline calculation methods (FMM, natural, periodic, monoH.FC)
- Customizable plotting parameters including symbol types, sizes, and dimensions
- Options for polygon visualization of pH variations
- Adjustable daily hour limits for monitoring specific pH conditions
Data Handling
- Imports data from Excel files (both .xls and .xlsx formats)
- Supports multiple worksheets within a single file
- Saves analysis settings for future use
- Exports results to CSV files for further analysis
- Generates comprehensive text reports with detailed statistics
Output and Reporting
- Creates detailed visualizations of pH trends
- Calculates trend lines for pH evolution
- Produces area and time calculations for periods above and below thresholds
- Generates summary statistics for all analyzed periods and groups
- Exports results in multiple formats for further analysis
The program provides a user-friendly graphical interface that allows researchers to thoroughly analyze ruminal pH data while accounting for the complexities of multiple sensor deployments and temporal variations in measurements.
