Cli Tac Interpolation#

Command-line interface (CLI) for interpolating Time-Activity Curves (TACs).

This module provides a CLI to interpolate TACs, enabling the conversion of these curves to a desired time scale. It uses argparse to handle command-line arguments.

The user must provide:

  • Input TAC file path

  • Interpolation interval in minutes

  • Output TAC file path

This script uses functionalities from :mod:’petpal.tac_interpolation’ module to interpolate the TAC based on the specified interval, or number of samples before the maximum value, and save the interpolated TAC to a specified output file.

An option to print the interpolated TAC to screen is also provided for visual inspection of the results.

Example usage:
Using petpal.cli_tac_interpolation.EvenlyInterpolate:
petpal-tac-interpolation --input-tac-path /path/to/input.tac --output-tac-path /path/to/output.tac --delta-time 0.1
Using petpal.cli_tac_interpolation.EvenlyInterpolateWithMax:
petpal-tac-interpolation --input-tac-path /path/to/input.tac --output-tac-path /path/to/output.tac --samples-before-max 4
