DESILIKE Tests for Cosmological Inference

This repository contains useful scripts and environments for performing parameter inference from cosmological surveys, specifically using the DESILike and CosmoPrimo packages.

---

Overview

This repository focuses on:

• Implementing and testing cosmological inference pipelines.
• Extending the FOLPS framework to Modified Gravity (FMG) scenarios.
• Providing ready-to-use environments and examples for researchers working with cosmological data.

---

Requirements

To use the FOLPS scripts, you need to download the official DESILike and CosmoPrimo packages from their respective repositories:

• DESILike Repository
• CosmoPrimo Repository

---

Installation Instructions

1. Set up the environment

To use the FMG scripts create the required environment, following these steps. By default, the environment will be named fmg_env, but you can rename it if needed.

conda env export > environment.yml
conda env create -f environment.yml

2. Install the modified DESILike and CosmoPrimo packages

Run the following commands to install the modified branches of DESILike and CosmoPrimo:

python -m pip install git+https://github.com/cosmodesi/cosmoprimo@dgbranch
python -m pip install git+https://github.com/cosmodesi/desilike@dbranch

---

Usage

To run the Modified Gravity FOLPS (FMG) scripts:

1. Ensure the FMG.py file is in the same directory as the scripts you are running. ⚠️ Note: This is a temporary requirement and will be improved in future updates.
2. Follow the examples provided in the repository for your specific tests.

Future improvements

-Automating the installation of FMG.py to eliminate manual steps.

-Adding more detailed examples and pre-configured tests.

-Improving compatibility with other cosmological tools.
