Introduction

SEP has always been interested in displaying and interacting with multi-dimensional datasets Biondi and van Trier (1993); Claerbout (1981); Clapp et al. (1994); Clapp and Biondi (1994); Clapp (1995); Mora et al. (1995, 1996); Ottolini and Rocca (1986); Ottolini (1983, 1988, 1990); Sword (1981) In 1997 Rick Ottolini provided SEP with an extension of his old X11movie program written while at Unocal. In the last two years I have added several additional features to the code. These changes include:

picking

Expansion of the picking ability including some degree of auto-picking.

annotating

The ability to annotate figures and then output the same view using SEPlib programs.

velocity

The ability to do velocity analysis.

multiple depth

The ability to work on X environments that do not have support pseudo-color.

multiple views

The ability to have multiple views of the same-dataset or two equivalent datasets.

This paper explains how to use each of these new features.
