srfpython's Introduction

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 py27-srfpython python=2.7 --yes
conda activate py27-srfpython
python --version  # must be 2.7.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 python2 (optional):

# make sure the environment is activated
conda activate py27-srfpython

# install with
conda install --yes notebook ipykernel
ipython kernel install --user
