How to read beat to beat annotation of MIT BIH AF database in MATLAB??

I want to calculate sensitivity, accuracy of my algorithm for AF detection. I have already got the result of my algorithm for every beat. To calculate True positive, True Negative, False Positive, False negative I need to know the reference beat to beat result provided in the annotation files. For my work I used MIT BIH Atrial Fibrillation Database. But I can't find a way to read the beat to beat annotations that provided in the database. How can I read those beat to beat annotations and import it in matlab if anybody knows please help me.

Hi Mahdi,

You can use the 'WFDB toolbox' for MATLAB R2014a onwards to read and process PhysioNet data. The 'rdann' function in the toolbox reads the annotation files for WFDB records. You can refer to the following documentation to know more about installation of 'WFDB toolbox' :
