NAME
       extstack - extract images from objects with rotational symmetry

SYNOPSIS
       extstack

DESCRIPTION
       This program will extract subsections from a symmetrical object and
       create a stack of normalized subsections as the output. It works best
       when used upon a symmetrical object such as an axoneme cross-section.
       The input requirements are:
              1) An image file containing 1 or more sections
              2) A point file ( corresponding to (1) ) containing
                 a point at the center of every subsection to be
                 extracted.
              3) A point file ( corresponding to (1) ) containing
                 all of the points used to determine the section
                 center.
       The program requires that the dimensions of the subsection box be give
       as the edge lengths of the box.  An additional subsection rotation may
       be specified.  The output will be an image file containing all of the
       normalized subsections.
