%[matdata]=asc2mat(datain,ntr,nsmp,smpr,st,et)
%
%This function converts an ascii matrix with rows representing samples
%and columns representing traces to a DSI formatted datafile
%
%ntr=number of traces
%nsmp=number of samples
%smpr=sampling rate (in seconds)
%st=start time (seconds)
%et=end time (seconds)
