SEPlib is SEP's package for processing seismic data. It is based on a hypercube concept. All data regular, or irregular, exists within a regular grid. The main SEPlib webpage is available from the SEP website. The latest version of the softare can be found here. A Mac tarball compiled on MacOSx can be found here. You should install this tarball in /opt/local/SEP.
