% Crosswire file for SEG-Y data into DSIsoft format 
% using the segy2mat function.
% This version is designed for the Seismic-Unix (SU) version of 
% SEG-Y output, with our convention for trid (43=vertical, 44,45=horizontal). 
% segy type values are 1 for char, 2 for int16, 3 for int32
% Note that mat2segy uses the same crosswire file, the multiplier and
%additive constant being interpreted instead as a divisor and subtractive
%constant.  The same crosswire file is used in both directions.
