Problem with OSCAR: I Can't Delete a Day

I had not used CPAP for a while and came back to it recently. I found that Sleepyhead development is discontinued and downloaded OSCAR. The software runs well and I imported my old data and started using OSCAR with my Resmed S9 Autoset. Everything seemed okay and I then began importing data from a CMS50F and that went well.

However, after a few days, suddenly, OSCAR reported my most recent session was May 11 and it was only April 30th. I also noticed that there were some rogue sessions reported from days in April when I had not used the devices. This happened on both machines on which I tried the process.

After some searching I found I can delete a specific day from the Data menu, so I successfully deleted three of the spurious days and then was able to see, "Nothing here" on those days.

However, on a few remaining days (2) that were highlighted in the calendar and showed some partial data (no pie chart, incomplete summary, strange waveforms) on the Daily page, I attempted to delete the data, but nothing happened.

So, I have few of those days polluting my reports and would like to get rid of them. I examined the data folder, figuring I could find and delete that date there, but could not make any sense of the files, even after decoding what appears to be hex filenames.

(How) can I delete data for these corrupted days? There are only a few, but they are distorting the reports.

Is it possible?

You should change the title of your post to something meaningful...

maybe "problem with OSCAR, can't delete data"

Done. Thanks.

Done. Thanks.

Much more likely to catch the attention of someone that can help with the problem that way

There are bugs with any software.
The thing about OSCAR is that it is honestly stated to be beta--
unlike commercial programs, which are implied to be finished--
until bugs are inevitably found.

There have been a few days in my life that I wish I could now delete. And I think I may remember a few that never really happened. But every brain has issues, and I'm pretty sure mine is still in beta.

I've had similar happen - importing in the future. 2 or 3 times. I've always been able to purge the day, and when I re-import after purge the data comes in on the correct day. But then my pressure settings aren't reported correctly in the left pane, or anywhere else for that matter. I'll see "Fixed 0" or "Min .3, Max .16" - both of which sound very uncomfortable!

No suggestions really - other than to head over to the "OSCAR Suggestions" thread and make the developers aware of the issue. I should do the same.

Thanks. I'll do that. One issue seems to be that deleting a day's data does not get all the references in the data store or perhaps subtract that day's addition to a cumulative total somewhere. In some cases the data day delete does not have any effect and a partial entry for that day remains. That may be partly due to how the data is stored. I tried looking at the data store and could make no sense of it. I had an idea how it is structured, but no idea how it is coded or what the relationships between the files might be.

In case it helps anyone, thanks to tip received by PM I learned that the files in the data store are named by the date and time of each day's beginning moment stated in Unix epoch time, as a hexadecimal number.

As I write the time is/was 5CCDED72 and is incrementing by the second

To convert these numbers to your local time see https://www.epochconverter.com/hex and paste in the file name (sans dot and extension).

Then delete the offending session, at your own peril, of course.

I should add that your data store folder can be found in the Help/About OSCAR (or Sleepyhead).

Back the whole folder up before performing surgery and as always YMMV.
