SleepyHead display of some data is wrong
My SleepyHead 1.0.0 is wrong in “Overview” display of AHI data more than 1 month old (more than 28 to 32 days ago). Has anyone else experienced this? Do I have something wrong in my Settings?
My ResMed VPAP machine stores this data in the file “STR.edf”. I viewed the data with an edf reader; the data is OK. AHI, CA, OA, UA, and H are all OK. I know the correct values from my pen and paper notes. Also, I have backup ResMed data from previous months; each backup Overview display is OK for the data 1 month most recent, but it is different than Overview taken 1 month or more later. Is it possible ResMed somehow corrupted “STR.edf” in a way that causes SleepyHead to incorrectly display data that is OK in that file? If so, would it be safe for me to delete (with backup) the file STR.edf from the ResMed data card; will ResMed generate a new good STR.edf, or does that file contain critical unique information for restart after power outage?
I see this problem in both Windows and Mac, current versions. Including the “BrokenGL” version. I have 2017 Overview data that was OK - old paper printouts from SleepyHead and screen shots of the Overview. I have notes about seeing this problem in 2013, but it went away. I do not have old versions of SleepyHead.exe, although I have all my backups of the data (since 2012 initiation). Is this a recurrent bug in various versions of SleepyHead?
My 2017 backups of the data that is correct on those old prints & screen shots: When I load those backups today, the Overviews show this kind of wrong data - clearly different than 2017. When I load the corresponding 2017 “profile”, 1.0.0 gives me a pop up that it needs to reanalyze for this new version using the backup located in the “profile”; when I click OK the Overviews show the wrong data. I cannot “review” the 2017 results, but it is noteworthy that the backups have the 2017 STR.edf file, which is evidence the problem is not the current STR.edf.
The “wrong data” is subtle; it is possible others have this problem but do not notice it. Here are some details for what I am experiencing: Total AHI values are too low - variable, but roughly 1/3 to 1/4 the correct value. On days when I do not use the VPAP the Overview correctly shows blanks. On days when the correct AHI is much higher than typical, more than a month in the past, the Overview shows a low value that is much higher than adjacent values. My true CA is almost always much larger than my true OA, but the Overview more than 1 month ago shows CA about the same as OA, both low, so the CA data are “more wrong”. The data from the current month (28 to 32 days) is OK with CA much larger, but that data comes from the files in the “Datalog” folder, not from STR.edf.
