function seismic1=s_multi2one_trace(seismic,header)
% Function converts the traces of a data set into individual one-trace datasets.
% The result is a structure vector of data sets

% INPUT
% seismic   seismic dataset
% header    optional; mnemonic of header whose value is to be added to 
%           the dataset name as (header = headervalue)
% OUTPUT
% seismic1  structure vector of one-trace datasets; thus selecting the third
%           trace
%              temp=s_select(seismic,{'traces',3}), 
%	    where "seismic" is the input dataset can now be achieved by
%              temp=seismic1(3)
%           where "seismic1" is the output data set
