%dispseis
%
%GUI interface program for displaying seismic data in DSI format.
%DISPSEIS calls up a menu for loading a dataset and selecting plotting
%parameters.  There are options for plotting with energy balancing or agc
%scaling.  Display options include wtva, va, wt, and grayscale.  Polarity
%reversal and zoom are available and mouse position can be tracked by
%pressing down the mouse button within the plot window.
%
%DISPSEIS can also be used to display seismic attributes data.  Seismic
%attribute (SA) data is stored in a DSI format variable with file header
%word 4 set to 1 as a flag.  There are normally either 3 (single
%component) or 9 (for 3 component data) records in a SA variable.
%Each component of the initial dataset has 3 records set aside for
%instantaneous amplitude, frequency, and phase information in that order.
%
%DSI customised processing software
%written by K.S. Beaty January, 1998

%num2str was truncating the value for t2 as a string.  The string when read back
%in then was the wrong value, the array size was calculated incorrectly and all hell
%broke loose.
