Installation and running Bjet_MCMC

Installation

You first need to clone the Bjet_MCMC Github repo in your local computer with

$ git clone https://github.com/Ohervet/Bjet_MCMC

Ensure all dependencies are installed, see Dependencies. Recommended: create the conda env “bjet-mcmc” from environment.yml using

$ conda env create -f environment.yml

If you use an updated version of Bjet_MCMC from a previously installed version, you might need to update your conda environment, with

$ conda env update -f environment.yml  --prune

Then load your environment with

$ conda activate bjet-mcmc

Running Bjet_MCMC for the first time

1. Create a copy of mcmc_config_template.txt called mcmc_config.txt. For information and customized configuration files, see Configuration file.

2. Ensure the data file is well formatted and is at the relative path specified in mcmc_config.txt, see Data format.

3. Install Bjet-mcmc with pip install -e . (in top directory, where setup.py and pyproject.toml are located). This also compiles the C++ code (see Running Bjet manually (bjet_core)).

4. First time use: execute blazar_initialize with python blazar_initialize.py or python3 blazar_initialize.py depending on your Python setup. This creates all necessary folders. If using python blazar_initialize.py, you must be in the directory bjet_mcmc.

5. Execute blazar_run_mcmc with blazar_run_mcmc, python blazar_run_mcmc.py or python3 blazar_run_mcmc.py depending on your Python setup. If using python blazar_run_mcmc.py, you must be in the directory bjet_mcmc.

6. Retrieve and check the results (see Outputs).
