Thanks for your wonderful and impactful work! We are planning to use below datasets to create commercial solution. In this respect, we would like to check whether we are allowed to develop commercial solutions where internally these datasets are used to train an algorithm.
I have a query regarding the date of actigraphy and edf file.
In the actigraphy file, we have 17(starting from 3rd oct 2018) dates for BOGN00001.
But in edf file as a start date we have '01.01.85' .
So how to understand the date at which edf files(PSG) were collected , so that i can correlate the edf files and actigraphy data
I was trying to understand the Actigraphy data from STAGES. but i could not see the activity count inside the json files of this link https://sleepdata.org/datasets/stages/files/m/browser/original/De-identified%20Data/Actigraphy%20Final%20to%20Post.zip.
Here i could see a parameter namely, Activeness. Does this Activeness correspond to Activity count ?
Inside MESA dataset, i could see activity count, light intensity information as well inside actigraphy.
So could you please guide me how to interpret the actigraphy data of STAGES dataset?
I really appreciate your work in generating the datasets!!
I have a query regarding STAGES Dataset. In the edf file, i could not observe ECG signal in the headers. Below are the headers available:
'E1M2', 'E2M2', 'C3M2', 'C4M1', 'O1M2' ,'O2M1', 'F3M2', 'F4M1', 'F1M2', 'F2M1', 'FLOW', 'PTAF', 'SNOR', 'EKG', 'THOR', 'ABDM', 'RLEG', 'LLEG','32','CFLO', 'LEAK', 'IPAP', 'EPAP', 'ETC2', 'WAVE', 'POS', 'DC08', 'T3M2', 'T4M1', 'SpO2', 'Plth', 'CHIN', 'Pz', 'P4'
We could see that EKG and ECG are same . So is that the reason why EKG is given here in headers?
Could you please let me know if i have misunderstood any of the variable wrongly or ECG is present in the above headers?
Thank you for your response!!
For the analysis of https://sleepdata.org/datasets/shhs/files/m/browser/datasets/hrv-analysis/shhs2-hrv-5min-0.19.0.csv is the tool mentioned in https://physionet.org/content/pcst/1.0.0/ is used OR any other tool was utilized?
If the tool from physionet is used, Could you please let me know what are the configuration settings used for analysis?
For eg: HRVparams.sqi.LowQualityThreshold is one of the settings parameter. Could you please help me understand what was the value set for this parameter during the 5 minutes csv features generation.
Similarly if any other settings parameters were used, could you please help me understand them?
I was trying to understand the HRV analysis of SHHS dataset - shhs1. I could see that, the HRV features are starting from a Start_sec , say for example, for ID 200079, the Start_sec is 6960, the features from 0 to 6960 is not available. But the corresponding annotations file has label from 0 to 6960 as WAKE. So could you please let me know why the HRV features are not available from 0 to 6960 secs?
