@function [dataout]=pack_good(datain,flg)

%function [dataout]=pack_good(datain,flg)
%
%Pack_good is similar to the INSIGHT module with the same name.
%It is designed to remove traces flagged as bad (trace header word 6 has
%been set to a number of less than 0) from the dataset.
%
%datain should be in official DSI data format
%flg=0 or left out -> bad traces removed from dataset
%flg=1 -> bad traces set equal to 1.0e-10 (used to retain trace spacing for
% fk filtering
%
%'kill' can be used to flag bad traces.
%
%DSI customized VSP processing software
%written by Kristen Beaty November, 1997
