Thanks sincerely for your contribution,I have some difficulty.

Thanks sincerely for your contribution,I am a fresher.I am reading some paper in estimating RR and HR,then I meet your project.Now I am facing some difficulties,could you please give me some instructions?
1.Where can I download Vortal dataset? Must I contact [email protected] to obtain data from young subjects both at rest and recovering from intense exercise?
2.When I use toolbox v.2,must I use 2 dataset(at rest and other),then combine the results of these two analyses ? Can I only use Synthetic dataset to obtain some results rather than using two dataset before?
Thanks again for your code.

When I use toolbox.must I follow the step you described one by one? If I have only Synthetic dataset,I set parameters in setup_universal_params.m,then I call RRest('rrsynth'),at last will it render some results?please give me some advice.

Thanks for your questions. Here is some advice which I hope will be helpful:

• Reading about estimating RR: I would recommend reading our recent review paper on estimating RR from the ECG and PPG. It provides an introduction to the topic, and also provides references to a wide range of papers on the topic. In addition, if you are considering using the RRest toolbox for your work, then I'd suggest reading the tutorial paper which provides an introduction to the algorithms. Incidentally, I will be giving an introduction to the topic in a webinar tomorrow, which will also be available to watch afterwards.

• Downloading the Vortal dataset: The Vortal dataset is available for use, subject to the terms and conditions of use. The dataset can be obtained by emailing [email protected] . They will provide further details of the terms and conditions, and once these have been agreed to, they will be able to share the dataset in Matlab format. A brief summary of the available data is provided here. Currently, recordings are available from young and elderly subjects. Recordings are available from all subjects whilst at rest, and in addition recordings are available from young subjects whilst recovering from intense exercise.

• Do I have to use both the rest and recovery (rec) datasets: No, the RRest algorithms will work with just one dataset (e.g. either rest or rec). For instance, if you want to analyse the rest dataset then you would use the Matlab command RRest(VORTAL_rest). Similarly, if you only want to analyse the recovery dataset then you'd use the command RRest(VORTAL_rec). You may also want to analyse the synthetic dataset.

Thanks sincerely again, when I run the code as peterhcharlton describe, the result is smooth. But there may be some small accidents while someone else are using,such as function create_table_of_algorithms(up) in RRset.m, actually error may meets when it call xlswrite(path,result), it is because of add-on issues. While meeting it, just open the excel software, excel options - Add-ons - COM add-ons to go - to remove the hook in front of the add-in, then it works well.Hope everyone make progress,thanks.
