Not enough data for this WTV_sd method Sampling frequency must be finite.!! #32

Hi everyone, I just faced this problem with some few files. When I try to extract the data it gives me the following error: "

myPA = findPA('29835_0504062018.cwa','site',1,'side',1,'mass',68,'bodyFat',0.2,'epoch','days','csv','29835_0504062018.csv'); progress: 0 percent current path:

Status: Calculating the PA data.

progress: 1 percent progress: 1 percent progress: 2 percent progress: 2 percent progress: 3 percent progress: 4 percent progress: 4 percent progress: 5 percent progress: 5 percent progress: 6 percent progress: 7 percent progress: 7 percent progress: 8 percent progress: 8 percent progress: 9 percent Not enough data for this WTV_sd method Sampling frequency must be finite. Error using vertcat Dimensions of arrays being concatenated are not consistent.

Error in findPA (line 195) PAdata.Raw = [PAdata.Raw; calcPA(filename, p.Results,fileinfo,startTime(i),stopTime(i))]; "

Could someone help me with that?

Thanks Hosam

Could anyone help me with that, please?

(Closing old issues) Apologies for the very late response.

If this is useful for anyone else finding this issue in the future:

I believe you are using the findPA.m file, but I am afraid I'm not able to help much with your issue.

Something that may be relevant: that old code uses "AX3_readfile.m", which only supports AX3 recording in "packed" mode. If you are using "unpacked" mode (or an AX6), you would need to convert the code to use CWA_readFile.m instead.

A popular alternative choice for processing wrist-based raw accelerometry is GGIR, and there is a good introduction to the package available, and a getting started guide.
