RE: Files of .acq format [ Reply ]

The .txt file must contain the RR intervals in a single text column, representing these distances in seconds. Here is an example of the required file format:

https://rhrv.r-forge.r-project.org/tutorial/example.beats.

The .txt file generated by Biopac software likely contains much more information. It's important to note that RHRV takes as input distances between heartbeats, not electrocardiograms. If you have acquired an electrocardiogram, you will need to use a heartbeat detector first.

Thank you for the prompt response Abraham. I am trying another approach: I can save each of the .acq files as .txt using the Acqknowledge software (linked with BioPac). However, I am still struggling to import the files into the hrv.data dataframe. I am not sure if perhaps the structure of the .txt file is incorrect or I am incorrectly trying to import the data.

Please could you advise on how to import the .txt files into the hrv.data dataframe that I created following the tutorial step: hrv.data = CreateHRVData() ?

Thank you very much

From what I've seen, it seems to be a proprietary BioPac format. The only thing I've found that might help you is this Matlab code that would allow you to load the data and export it to another format: https://es.mathworks.com/matlabcentral/fileexchange/14562-load-biopac-acq-acqknowledge-for-pc-data

Good day, I recorded ECQs using the BioPac system, which saves the files as .acq. I now have ~300 files in this format for which I need to analyse HRV.

Is it possible for the RHRV package to use files that are .acq? And if yes, please could you advise on how.

I am struggling to find a solution for converting these files to ASCII, so ideally I'd like to avoid having to convert the files. Thank you in advance for your assistance.
