When I use the batch preprocessing script I am getting a message in purple in the processing window that says "Warning no correlation between master dark and target frames". It seems to be processing the flat frames at the time.

I don't understand this, I use a master dark for the sub length that was created from a previous image I processed. You get your registered images etc and in the master diectory is puts the masters. I just copied this to a general master directory and I then use this master dark for every 10min sub project.

Is there some other way I was supposed to create a master dark?
