I notice from another thread that you are starting with raw FITS files from QHY247C. Is this still the case? The only thing I can think of is maybe the information about Bayer pattern "RGGB" is not being found by DrizzleIntegration for some reason or there is some other reason that DI is upset by working with raw FITS files. For instance, I wonder if some header keyword needs to set within those files?

Yes I am using raw FITS. A keyword header is was what I was thinking too, but I have no idea what to add or how to add it. I have been selecting the pattern manually instead of using Auto too, both in Debayer and when I try DrizzleIntegration. Both RGGB.

How frustrating. There is also no keyword solution. Here (https://pixinsight.com/forum/index.php?topic=11466.0) Juan says the following about FITS files:
You say you are setting the CFA pattern manually at each step, so I can't see what else you can do. I assume you have already tried BPP for your Bayer Drizzle pipeline? I ask because earlier in this very thread (https://pixinsight.com/forum/index.php?topic=7184.msg58989#msg58989) Juan says:
Has anyone successfully Bayer Drizzled FITS files with PI 1.8.5. If so, what did you do?

"PixInsight 1.8.5 implements a new automatic CFA pattern detection mode in the Debayer tool and the BatchPreprocessing script (which uses Debayer internally). This mode works perfectly for DSLR raw files. However, FITS files cannot store information on CFA patterns, so you have to select the Bayer pattern of your camera manually in the BPP script. The same is true for the Debayer tool if you use it directly."

Right now the Bayer drizzle method can only be implemented as an automatic process using the BatchPreprocessing script. An optimal implementation of Bayer drizzle requires a tight integration with a preprocessing pipeline, such as BPP.
