SrfPython

• programs for surface wave dispersion curves in python
• compute, display, invert 1D depth models
• based on Herrmann codes Computer Program in seismology

Install

Pre-requisties

• git
• Anaconda3
• gfortran

Install instructions

• Go to the installation path (e.g. "~/git") and get srfpython

cd ~/git
git clone http://github.com/obsmax/srfpython.git

• Create the virtual environment and activate it

conda create -n py3-srfpython
conda activate py3-srfpython
python --version  # must be 3.X, or conda failed, retry in new tty

• Go to the cloned repository and install the package

# install in editable mode 
# i.e. changes in python programs do not require re-installing the package
cd ~/git/srfpython
python -m pip install -e .

# test the compilation using 
# (must work anywhere, no need to custom path or anything)
srfpython_tester.py

• If you wish to use the jupyter notebooks with python3 (optional):

# make sure the environment is activated
conda activate py3-srfpython

# install with
conda install decorator=4.4.1 jupyter --yes
