41This package contains seven programs that may be useful
42to people who work with Plate Tectonic Reconstructions.
43The eight programs are
44
45 backtracker - Move points back/forth in time
46 grdpmodeler - Create gridded predictions from plate models
47 grdrotater - Reconstruct data grids using finite rotations
48 grdspotter - Create CVA grids using grids of bathy/faa
49 hotspotter - Create CVA grids using seamount locations
50 originater - Associate seamounts with hotspot point sources
51 polespotter - Find stage poles from fracture zones and abyssal hills
52 rotconverter - Manipulate finite and stage rotations
53
54Documentation via RST files produce HTML, MAN, and PDF pages that
55give full description of the program interfaces.
56Furthermore, example scripts (UNIX shell and DOS batch) are
57provided which demonstrate how to use the programs on the
58enclosed data set and Euler poles. Note the GMT test/spotter
59directory contains additional example of spotter usage.
