Description

My name is Marco Fonsato and I'm a master's degree student that is working on a project for my thesis that will include get_hrv script (of course with citation).
I've got problem that i'm facing.
I cannot get the complete statistics for the frequency domain.
In particular, even when i'm using the file that is present in the tutorial :

get_hrv -f "0.2 20 -x 0.4 2.0" -p "20 50" chfdb/chf03 ecg

I can't get all the powers: i'm only able to get the TOT PWR and the ULF PWR.
The images in the tutorial show a completely different set of data, including all the powers. This problem is present also when i use a diferrent file from Physionet or my personal files.
My question is: is there a particular way in which i could solve my problem? It is a known bug?

Thank very much in advance.

Kind regards

Research direction

Start with the get_hrv command and reproduce the reported tutorial invocation: get_hrv -f "0.2 20 -x 0.4 2.0" -p "20 50" chfdb/chf03 ecg. Compare its frequency-domain output with the tutorial images, focusing on why only TOT PWR and ULF PWR are reported. Done means the expected frequency-domain powers are produced consistently for the tutorial, PhysioNet, and personal files.
