I thought I'd give the batch preproc script another whirl just to see how it compares with my manual process. For some reason, it rejects all my master calibration files (including the superbias) and will only work if I use the original raw calibration data. I created these master cal frames using the process described in the tutorials and they work properly with the Calibration Tool.
However, if I use the master calibration images created BY the script and run it again using these images as master calibration images, it will run to completion.
Replacing the scripted-created master flat with my own and it again fails.
** Warning: No flat frames have been selected to calibrate light frames (filter="Luminance", binning=2, exposure=30.00s, length=6)
What's it looking for that the manually created master flat don't have?
