Get_hrv problem/bug
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
Hello. I haven't seen this issue before.
Which OS are you using, and did you compile the package from source? Did you also compile the plt and WFDB packages from source?
The page says that get_hrv relies on statnn, lomb, and pwr. If you call which statnn, which lomb, and which pwr, do you see them all installed?
Hey, thank you for your reply! I'm using Ubuntu 14.04. Yes, i believe so. I can see the scripts and all the source files in /usr/bin. I also have WFDB and plt, since i used them before HRV.
Any new suggestions? Sorry if i'm writing again, i know that you surely have more important things to do, but i can't find nothing about my problem. Thank you again @cx1111
