@function [dataout]=subr(datain1,datain2)

%function [dataout]=subr(datain1,datain2)
%
%subtracts traces in datain1.dat from those in datain2.dat and outputs
%the resulting traces to dataout
%similar to INSIGHT module 'subr'
%
%datain1 and datain2 must have same number of records, traces, points per
%trace, and time scales
%user should make sure that same time shifts have been applied to both
%
%DSI customized VSP processing software
