Thanks for your inquiry. Yes, you can link the datasets that contain the personal history data (e.g. ADHD diagnosis) by looking at the obf_pptid field in the dataset. This is the first field in the file and is the unique identifier for each CHAT subject. These IDs also exist in the names of the EDF files that you have downloaded. For instance, chat-baseline-300001.edf was taken from obf_pptid = 300001 in the main CHAT datasets.
obf_pptid = 300001
Let us know if you have further questions!
We have released the 0.6.0 dataset for the Sleep Heart Health Study. This dataset corrected a minor oversight from 0.5.0 and also included the recoding of age variable values of 90 and above. The latter was implemented to more closely match the HIPAA guidelines on Protected Health Information.
Whoa, nice catch!
These should now be fixed and available for download. I see we had a bug in our R script that we used to extract the staging epochs from the Profusion XML annotation files. Sorry for the inconvenience.
I had a couple questions:
The first version of the Cleveland Family Study Visit 5 dataset is now available. This dataset accompanies 730 EDF and XML annotation files that are available for more in-depth analysis.
Future dataset iterations for CFS will include more variables, along with data from earlier study visits.
Here's a summary of the release:
A new CHAT release is now available on sleepdata.org. There were not a significant number of changes made to the dataset, although we importantly removed a small number of subjects whose data were struck from the CHAT analytic datasets. Read more below.
Good news -- I have the go-ahead to make the full SHHS XML annotation files available on sleepdata.org. My target will be to have them up by the end of next week (06/27). I will update you again when that happens.
Edit: The SHHS XML annotations are now available here: https://sleepdata.org/datasets/shhs/files/
Thanks for your question and for joining sleepdata.org.
We do have another set of XML annotation files for the SHHS sleep studies. These files contain the respiratory events of interest with timestamps and durations, as you would expect. We have been holding off on posting these because of some issues we were trying to resolve with missing oxygen desaturation events (that should have been present in the files). I will raise the topic at our next group meeting on Tuesday (06/17) and make a clear plan of action. My desired goal would be to post the XML files we do have within the next 1-2 weeks, with any problems noted within our dataset documentation.
