@function [dataout]=kill(datain,kword,bad)

%function [dataout]=kill(datain,kword,bad)
%
%similar to 'kill' module in INSIGHT
%marks bad traces by writing '-1' to trace header word 6
%marked traces will be omitted when using filtering modules
%marked traces can be removed using the function 'pack'
%
%datain is in DSI official data format
%kword is the trace header word number by which bad trace is identified
%       kword=1 sequential record number
%       kword=26 receiver station
%       kword=27 shot station
%bad is a vector of numbers identifying the traces to be flagged
%
%DSI customized VSP processing software
%written by Kristen Beaty October, 1997
