error ConvertRawDataToRRIntervals

[vimazz]

Hello!
Finally, I successfully run the Basic_Demo with my own ecg imported from acq file: thanks Giulia!!

Then I got this error running the other script:

ConvertRawDataToRRIntervals(ECG_RawData,HRVparams,'HC1')
Subscript indices must either be real positive integers or logicals.

Error in bsqi (line 43)
endtime = max([ann1(end), ann2(end)]);

Error in ConvertRawDataToRRIntervals (line 66)
[>>SQIjs, StartSQIwindows_js] = bsqi(jqrs_ann(:),sqrs_ann(:),HRVparams);

and empty results running the Main_HRV_Analysis. I tried also several windows lengths.
I assume that my own data are ok since the basic demo script got the r_peaks.
On the other hand, where am I wrong?

Thanks in advance!!!

Hello,
I guess this problem comes from the run_sqrs.m that gives ans empty. Since this script suggests to use an FIR band-pass filter first, I run the bp_filter_005_40EGC.m. Unfortunately the run_sqrs.m ans is still empty. My raw ECG data have been acquired by Biopac during a fmri session: I used the comb band stop filters as suggested by Acqknowledge. Maybe the data are still too noisy?
Any suggestions?
Thanks in advance!
