timesat-cli 1.2.2

Python-based command line interface for TIMESAT

TIMESAT CLI

TIMESAT CLI is a command line interface and workflow manager for the TIMESAT package. It provides a convenient way to configure and execute TIMESAT processing pipelines directly from the command line or automated scripts.

---

Requirements

Before you begin, make sure you have:

• Miniconda or Anaconda (for environment management)
  Download: https://docs.conda.io/en/latest/miniconda.html
• Python 3.10+

---

Installation

timesat-cli is available on PyPI and can be installed using pip or uv.
Although it is not published on Conda, you can safely install it inside a Conda environment.

Option 1 — Install inside a Conda environment

conda create -n timesat-cli python=3.12
conda activate timesat-cli
pip install timesat-cli

This approach uses Conda only for environment isolation.
The installation itself is handled by pip, which will automatically install timesat and all required dependencies.

---

Option 2 — Install via uv (recommended for pure Python environments)

uv is a modern, high-performance alternative to pip and venv.

1. Install uv:

   pip install uv
   # or
   curl -LsSf https://astral.sh/uv/install.sh | sh
   

2. Create a virtual environment and install the package:

   uv venv .venv
   source .venv/bin/activate
   uv pip install timesat-cli
   

uv provides faster dependency resolution and caching.
It will automatically install timesat and related dependencies.

---

Option 3 — Direct installation with pip

If you already have Python 3.10+ installed:

pip install timesat-cli

---

⚙️ Optional: Parallel Processing Support

timesat-cli provides an optional extra for parallel execution using ray.

To install with parallel-processing support:

pip install timesat-cli[parallel]

This installs the base package plus the ray dependency.

---

Running the Application

After installation, start the GUI with:

timesat-cli path/to/settings.json

or equivalently:

python -m timesat_cli path/to/settings.json

---

Advanced Usage

If you wish to customize or extend the workflow, you can also run or modify the main script directly:

python timesat_run.py

The file 'timesat_run.py' contains the full example pipeline that invokes core modules from the 'timesat_cli' package, including configuration loading, file management, TIMESAT processing, and output writing.

HRVPP Notes — QFLAG2 weights

If you work with HRVPP quality flags (QFLAG2), the following weights w are commonly applied:

QFLAG2 value	Weight w
1	1.0
4097	1.0
8193	1.0
12289	1.0
1025	0.5
9217	0.5
2049	0.5
6145	0.5
3073	0.5

Example (settings.json):

"p_a": {
  "value": [
    [1, 1.0],
    [4097, 1.0],
    [8193, 1.0],
    [12289, 1.0],
    [1025, 0.5],
    [9217, 0.5],
    [2049, 0.5],
    [6145, 0.5],
    [3073, 0.5]
  ],
  "description": "QA weighting rules. Leave empty [] to keep original QA values. Use [qa_value, weight] for exact matches or [min, max, weight] for ranges."
}
