Annotation Out of Sync

[GoogleCodeExporter]

What steps will reproduce the problem?

When I am loading data in Matlab using the WFDB Toolbox for Matlab, a lot of 
annotations don’t show up at all, whereas they show up using LightWave. The 
script I use only changes the record name, extension, and N from the wfdbdemo 
script:

[~,config]=wfdbloadlib;
N=100000;
[tm,ecg]=rdsamp('mghdb/mgh001',[],N);
[ann,type,subtype,chan,num]=rdann('mghdb/mgh001','ari',1,N);
plot(tm,ecg(:,1));hold on;grid on
plot(tm(ann),ecg(ann,1),'ro');




Also, it appears that some annotations are significantly off, see this link:

What is the expected output? What do you see instead?
