%
%function [matfile]=ita2mat(fhfile,thfile,datfile);
%
%
%This function reads in the 3 output files from the
%ITA poststack module ita2mat and creates a datafile
%in the DSI processing software format.  The record
%structure of the ITA file is preserved in the process.
%
%fhfile = file header file
%thfile = trace header file
%datfile = data file
%
%The file names should be separated by commas
%and between single quotes (as strings)
%
%DSI customized VSP processing software
%written by Gervais Perron Feb. 1998
