StrainProx

This repository contains reproducible material for: StrainProx: High resolution seismic time-strain estimation

Overview

StrainProx is a Python package for high-resolution seismic time-strain estimation using total variation regularized inversion and joint inversion and segmentation methods, using as building block proximal operators.

Project Structure

The repository is organized as follows:

• 📂 strainprox: A Python library that includes routines for the inversion algorithms and plotting functions.
• 📂 data: A folder containing the test data.
• 📂 notebooks: A collection of Jupyter notebooks that demonstrate StrainProx for time-strain inversion with the Hess model, and benckmark time-strain inversion methods.

Installation

Option 1: Using the installation script

./install_env.sh

The installation takes some time. If you see Done! in your terminal, the setup is complete.

Option 2: Manual installation

1. Create a conda environment using the provided environment.yml file:

conda env create -f environment.yml

2. Activate the environment:

conda activate strainprox

3. Install the package in development mode:

pip install -e .

Usage

Always activate the environment before running any code:

conda activate strainprox

Then, you can explore the example notebooks in the notebooks directory to understand how to use the package.
