Flat frame Normalization error - NormalizeCFAChannel

Which APP version are you using?

@vincent-mod I’m using the latest version for intel Mac. 2.0.0.beta12 

Same error with the newest release: 2.0.0.beta13

Tried with a different light and changed the flat.

Hi @astropolo,

Do the flat and light have the same raw dimensions and are they created in the camera or with capture software?

Hi @mabula-admin, the flat and the light have the same raw dimensions and were created in the camera. I've tested with Sony files (lights and flats) and didn't got the problem. 
 

Hi Mauricio @astropolo,

Okay, can you share the problem with us so we can investigate and solve this a.s.a.p. ?

Can you upload 5 lights, 5 flats, 5 bias and 5 darks?

Please make a folder with your name and issue, like Mauricio-Flat-issue and let me know once uploaded 😉

@mabula-admin just uploaded the files on the folder Mauricio-Flat-issue

Thanks for taking a look!

Hi Mauricio @astropolo,

Thanks for the upload, i will investigate a.s.a.p. 😉

Hi Mauricio @astropolo,

I tested with 2.0.0-beta13 and everything is working fine when I load the 5 lights, 5 bias, 5 darks and 5 flats.

Is the error happening when you load a single flat directly as a masterflat perhaps? (I just tested and this also works fine)

Is your Working Directory on an internal or external drive ?

Did you upload flats that create the problem on your sytem?

Mabula

Thanks @mabula-admin for reviewing it that fast!

Good to know it's working on another machine. I didn't load the flats as the masterflat and I was using an external drive as directory. Now I changed it to the main hard drive and I'm still getting the error with only 1 light and 1 flat.

I'm using a Mac with Ventura 13.1.

I'll try on a windows machine to see if it works ok. Not sure what config on the computer can make this error happen with the flat frame.

Dear @astropolo,

That flat file _DSF3552.RAF on which it happens in your screenshot was not uploaded, maybe you can upload that one so I can test it?

The problem should definitely not be Operating System dependent.

Mabula

@mabula-admin I used one of the 20 flats I had from that session ( I had the same problems with flats from another day).

Just tried with 1 of each (light, dark, flat, bias) from the ones uploaded and same thing is happening.

Uploading recorded steps.

Hi @astropolo,

Thanks for the video 😉

I did exactly the same as you showed and no problem on Windows, so maybe it is OS dependent, which makes it more weird.

I will test now on macOS to see if the error does occur there.

Hi @mabula-admin, I was able to create a Master Flat on Windows machine using the same Flats I was trying on Mac. For now I can create the Master Flat on Windows and then continue with all the processing on Mac.

Hi @mabula-admin, I was able to reproduce the same issue on windows with new flat frames taken today. Not sure if it's related to being taken at different Iso than the lights.

Was able to reproduce the same issue on Windows with the previous Flats uploaded, not sure how I could get one Master Bias the first time I've tried on Windows.
