Hi Mabula,

Firstly, a big thumbs up for the new multi channel/session functionality - makes life a lot easier and I think improved results as well. I have an idea for another improvement which I will post separately.

Unfortunately I have had a problem this morning calibrating multichannels (HA, OII, SII) over four sessions with Lights, Darks, Flats, Dark Flats and Bias frames.

The calibration ran to 90% and then just stopped, oddly APP has not completely crashed, I can still scroll the main and console windows and CFG/Info still open, however the Cancel button doesn't work.

I have plenty of storage, SSD for C: and a Samsung T1 SSD for the APP Directory on Windows 10 with 6GB RAM allocated. In case its of relevance I loaded the wrong Dark flights for one set of lights and "Removed" them and loaded the correct ones. Other than that I don't think I changed any defaults, just ticked the generate BPM button and then "Create Masters....".

It took a long time to load and check everything so I am a bit reluctant to try again and would be grateful if you could take a look. Let me know if there is any other information required (perhaps a log somewhere?). I have attached a screen print that shows the stage of processing when the freeze occurred.

Thanks

Jon

PS For information, the APP site is running very slowly today.

Thank you @midnight_lightning,

The provided information in the console and the calibration process is enough to know where it is stalling now. I will have a look immediately to solve this.

Hi Mabula,

I may have found the issue.

I have been trying different things since originally posting and noticed that the Lights from Session 1 frame IC1805 quite differently to Session 2-4. In Session 1 there is perhaps 10% to 20% difference in overlap compared to the other sessions. This is data from last year that I am reprocessing and I had forgotten that I messed up the framing on the first session.

So, I don't know for sure whether this caused the issue but I have rerun the calibration using data from sessions 2 to 4 and it worked fine.

Apologies if this is user error, I don't want to be wasting your time.

Jon

Hi @midnight_lightning,

No problem, I have investigated and I think it's not related to the amount of overlap between the frames 😉 but rather a concurrency issue between several threads. In almost all cases, the calibration process finishes like it should, but apparently, sometimes not. I need to do some more tests, but I think I have located the source problem 😉

Thanks,
