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.
The breakdown of the NSRR SHHS dataset, as originally taken from BioLINCC, goes like:

Thanks for inquiring about what do to as you bring on another user to your project. Our preferred approach is for your colleague to submit a DAUA for themselves. The contents of the DAUA could mimic your own and should mention your upcoming collaboration.
Thanks for checking out the site and SHHS dataset. I think the variation in the number of commas on each given line that you're seeing derives from the "Comm" variable/column. "Comm" is a free text field that includes scorer notes about the overnight sleep study quality. Some of these notes include commas. That said, these field values that contain commas will be contained within double quotes, which most CSV parsers should understand. The dataset reads into Excel, SAS, and R correctly for me.
Example snippet from "Comm":
1,0,0,6,"Lot of alpha-delta sleep but not alpha intrusion. Sleeps on back entire time, only change in position when awake. Airflow choppy at times (-1 hr), chest very small amp (- 1 hr), Low baseline saO2 ~92%, Desats into 70's in REM.",0,8,8,8,8,8,8,
Here's a Stack Overflow post that describes handling commas in a CSV file.
Hope this helps!
Thanks for checking out the resource. The approach you have outlined looks correct to me.
