WABP Example Looks Incorrect

[GoogleCodeExporter]

What steps will reproduce the problem?
The WFDB example does not look right:

 N=2000;
  [tm,x]=rdsamp('slpdb/slp60',2,N);
  [endTime,dateStamp]=wfdbtime('slpdb/slp60',N);
  wabp('slpdb/slp60',[],endTime{1},[],2);
  [ann]=rdann('slpdb/slp60','wabp')
  plot(tm,x);hold on;grid on
  plot(tm(ann),x(ann),'or'



What is the expected output? What do you see instead?
Beats annotated in the PPG signal (length(unique(ann))> 1)
