DBE: fails to generate background model image and misplaces extracted image

[LarryC]

Juan,

None of my other images from other data result in this DBE behavior. 

I re-created the same image that results in this DBE behavior from the same debayered data (which followed batch conversion, calibration and cosmetics correction - with the same master flats, biases and darks), and do not see the same behavior with DBE in other words, I re-star aligned and integrated).  Keep in mind that the original file was also fine initially.  It was at some point in playing around with the image in PI that the behavior suddenly began.   

Let me know if there's anything else I can provide if you plan to look into this more, but the new image is fine so I plan to delete the old problematic image and move on. 

Thanks for following up on this problem.

I can duplicate this behavior on every stack but not processed xisf image I have. I checked images from back in February to my latest in October. One thing I noticed is if I don't have enough samples(>3) and get the notice box letting me know my mistake, If I change say the tolerance for more samples, dbe seems to work. If I shutdown and restart PI, open the same image file and do the steps that make DBE fail but change the tolerance before executing dbe then the failure happens and no background image is generated.

To be honest I never operate DBE this way as I have always just drag and dropped the new instance on the image.

I'm running Windows 7.

Hi Juan and Group,
I'm the original poster of this thread:

As previously stated, PI will yield one of the following with the xisf file:
a) the expected DBE'd image and Background (but only rarely).
b) the DBE'd image only, no Background.
c) Neither (although the DBE'd image is hidden in the lower task bar workspace and can be retrieved).
 
I took that "xisf" file and saved it as a "fit".  The newly created "fit" file behaves consistently as expected with DBE.

Just FWIW.

I'm operating on a Dell XPS8300 with Win 7, 64 bit.  Monitor resolution is max'd at 1400x900.
