Welcome to the main page for the Stanford Exploration Project Library [SEPlib]. The current version [6.5.3], is generally more stable than the last version. This page is simply a “jumping-off” point since we assume you already have some familiarity with SEPlib. If you want to learn more about SEPlib, please see the SEPlib manual (link below).



Generally it is best to install SEPlib from source, especially on linux with its reliance on shared libraries that can vary in location. A brief guide on how to install from source can be found here.


Probably most SEP researcher have contributed in some way to SEPlib. However, some researchers stand out:

  • Robert Clayton introduced the original parameter fetching and did much ground breaking work concerning Vplot.
  • Jon Claerbout introduced history files.
  • Dave Hale wrote the libvplot library.
  • Stew Levin got SEPlib pipes to work and ported Vplot to DEC Gigi terminals.
  • Joe Dellinger perfected Vplot, the graphics library.
  • Steve Cole added dithering of rasterplots to Vplot.
  • Dave Nichols reworked the SEPlib input and output handling and introduced GNUmakefiles for easy installation.
  • Martin Karrenbach had a first SEPlib extension to handle irregular data.
  • Biondo Biondi and Bob Clapp (with the help of current SEP students) truly extended SEPlib to handle irregular data.

The directory seplib-5.1 contains software known as “SEPLIB” and “VPLOT”.
