pyDEXP is a open-source python package aiming at processing potential field data using the dEXP theory formulated by Fedi et al., 2012. The package largely benefits from the imaging methods module of the Fatiando a terra open-source python library.

Create a new environment:

conda env create -f environment.yml

Activate this environment:

conda activate pydexp

Install pydexp from setup.py:

python setup.py develop

Install pygimli from setup.py:

git clone https://github.com/gimli-org/gimli
cd gimli
conda develop .

Update pydexp:

conda env update --file environment.yml --prune

• pygimli (for the ERT and MALM forward modelling)

Pinned to the version 1.1.0: conda install -c gimli -c conda-forge pygimli=1.1.0

• fatiando 0.5 (for derivation of the potential field and upward continuation)

Pinned to the version 0.5 (git clone the repo for dev purpose)

Others dependencies are detailed in the requirements.txt file.
