I condensed the information about overlapping PSG and actigraphy in MESA and posted some guidance for users at this link: https://sleepdata.org/datasets/mesa/pages/actigraphy-introduction.md
I processed and deposited the HRV Rpoint files today for SHHS. The description and links to files are available here: https://sleepdata.org/datasets/shhs/pages/13-hrv-analysis.md
I don't know much about HRV, but the documentation provided by the creators of those data is here: https://sleepdata.org/datasets/shhs/pages/13-hrv-analysis.md
Sure, I will forward you the conversation I had with Joao, which contains a good deal of information about linking MESA PSG and actigraphy.
Thanks for checking out the resource. We do have the R-point annotation files posted for the MESA dataset: https://sleepdata.org/datasets/mesa/pages/hrv-analysis.md
You are looking to get similar annotation files for the Sleep Heart Health Study (SHHS), correct?
We should be able to do this, though it might take a few weeks to process and prepare for posting. I believe we could get the files posted sometime in July.
The Polysomnography Introduction page has some information about the two XML files.
They contain the same information in slightly different formats. The NSRR files were made to work with the EDF Viewer Tool.
I'm glad you find the data useful. All of the PSG records were annotated by a Registered Polysomnographic Technologist (RPSGT).
You can read more about the scoring procedures here: https://sleepdata.org/datasets/shhs/pages/mop/6-610-mop-overview-of-scoring.md
HCHS/SOL does not have any overlapping PSG and actigraphy data - these visits were a couple years apart. MESA does have a lot of overlapping data, but you can't do this automatically because we had to strip identifiers, including dates, from all the datasets.
I will send you a link to a supplemental dataset that will assist you in linking concurrent PSG and actigraphy in MESA.
The OAHI and many other variables are available in the CSV datasets in this folder: https://sleepdata.org/datasets/shhs/files/datasets
You could report the issue to the developer here: https://github.com/Teuniz/EDFbrowser
I'll ask members of our team here if they have used EDFBrowser. We don't have any direct affiliation with Teuniz, the EDFBrowser developer.
Edit: My guess is that EDFBrowser doesn't save/re-write EDF files. I suppose the changes you made using "Organize" would then be saved/loaded with a montage file.
