There are many data types and methods of analysis in rock and paleomagnetic investigations. The MagIC database ( was designed to accommodate the vast majority of data used in such investigations. Yet getting data from the laboratory into the database, and visualizing and re-analyzing data downloaded from the database, makes special demands on data formatting.

There are several recently published programming packages that deal with single types of data: demagnetization experiments (e.g., Lurcock et al., 2012), paleointensity experiments (e.g., Leonhardt et al., 2004), and FORC diagrams (e.g., Harrison et al., 2008). However, there is a need for a unified set of open source, cross-platform software that deals with the great variety of data types in a consistent way and facilitates importing data into the MagIC format, analyzing them and uploading them into the MagIC database. The PmagPy software package ( comprises a such a comprehensive set of tools. It facilitates conversion of many laboratory formats into the common MagIC format and allows interpretation of demagnetization and Thellier-type experimental data. With some 175 programs and over 250 functions, it can be used to create a wide variety of plots and allows manipulation of downloaded data sets as well as preparation of new contributions for uploading to the MagIC database.
