After using siril 1.2.0 successfully for 2 months, running OSC_Preprocessing and OSC_Extract_HaOIII, suddenly I’m unable to complete the Scripts due to the error below:
"14:09:11: Setting CWD (Current Working Directory) to ‘C:\Pictures_PC\Astronomy\NGC7635’
14:09:11: Script execution failed
I double checked the files location to make sure are in the right directory but same results
Images have different sizes
Also, I see you do have bias with 3 layers, so already demosaiced. Probably jpg mixed with FITS files?
I read: Reading JPG file, and also TIFF files. Looks like your folders are messy.
I found my files were messy as you said, removed wrong files and left only FITS, it seems one flat had different size, removed almost half of them as I was not able to identify the bad one.
