I just tried using the "Super Pixel" algorithm. I was expecting the integration result file to have a resolution of about half that of my original images, but it is about the same. I got a 3011x3014 output from 3008x3008 exposures.
I thought a block of 4 pixels would be converted to 1 pixel.
Have I misunderstood what Super Pixel does?
Be adviced that superpixel throws away possible valuable data, it's usually used to get a kind of preview on the data. Here's a snippet of the tooltip for it, it averages pixels before any de mosaic is performed :
I think it's better to try lowering the integrate scale (integrate tab, all the way down), if your goal is to simply downscale.
I tried Super Pixel again and it now produces a half width and half height image as you would expect.
...and now Super Pixel produces original sized images rather than half sized ones again!
Perhaps some other parameter overrides it?
...and now it's working again.
@jim Intriguing! What changed in between attempts? Did you choose different parameters? Did you restart APP? What version of APP are you using?

I had tried changing composition options (full, reference and crop) but that didn't seem to make any difference. I also tried restarting APP but that didn't help. However the following day, after a PC shutdown and restart, it worked again.
I'm on 2.0.0-beta2
Interesting indeed. You opted not to simply downscale then in the integrate tab?

Is that better than "Super Pixel" in any way?
If you want to downscale the image, then yes that would be better. Super pixel can throw away some of the data, which might impact a better registration of the data.
