PmagPy_calculations.ipynb This notebook demonstrates many of the PmagPy calculation functions such as those that rotate directions, return statistical parameters, and simulate data from specified distributions. The functionality of PmagPy is demonstrated within three notebooks in this repository: Markdown cells are for text and clicking on it will typeset the text.Ĭode cells are for code and clicking on it will execute the code. There are two types of cells: Markdown and Code - see the menu bar for the type of cell you just clicked on. To check it out, see:Ĭlick on a box (called a “cell”), then click on ‘Run’ in the menu bar. If not, we have a full course in Python for Earth Scientists available on Github. If you already have some experience working with Python, you should be able to navigate these notebooks. You will need to have Python 3 and Jupyter ( ) installed on your system to run this notebook. If you are running this notebook locally, you can click the following link to launch PmagPy-cli.ipynb What are paleomagnetism and rock magnetism? #įor information on the science of paleomagnetism and rock magnetism, see textbook at: Using Jupyter notebooks for Earth Science # For examples of how to use PmagPy scripts on the command line, see the static version of PmagPy_cli. These notebooks demonstrate how to use PmagPy in a Jupyter notebook or Python script. PmagPy is a software package for analyzing paleomagnetic and rock magnetic data using Python.
