Hi,
I am doing a project on ECG analysis using "Biosig Toolbox" from http://biosig.sourceforge.net/ I installed all the files as mentioned in the documentation but when I try to run the demo I get the following errors

??? Reference to non-existent field
'opentyp'.

Error in ==> sopen at 5761
HDR.FILE.FID =
fopen(HDR.FileName,[HDR.FILE.PERMISSION,'b'],HDR.MAT4.opentyp);

Error in ==> demo1 at 35
HDR = sopen(fullfile(P,F),'r');

I have not changed anything in the original code I downloaded the data file from Physionet.org I cannot figure out what am I doing wrong. Can anyone help me? I will be grateful to you for the same. plz help me out.
