No CFA pattern after Cosmetic Correction

[Luigi]

I calibrated my Nikon RAW (NEF) files in ImageCalibration (output of _c files).
I used the '_c' files as input to the CosmeticCorrection process.
When I debayer the '_cc' files, I get the error below. I *can*, however, debayer a '_c' file.

Did the CosmeticCorrection 'lose' the fact that my images are CFA?

I am on MacOS High Sierra, running the latest PI. Ideas?

Maybe you forgot to check the CFA-box?

I do have the CFA box checked. I am wondering if this is a regression introduced into CC, since I know I've used this process before. Or, I'm dense. One of those two

I uploaded a calibrated light and a cosmetically-corrected light to dropbox (and put a post in the 'Bug Report' forum)

Hi Luigi!
When you debayer the cc files instead of "Auto"
with "RGGB" evrything runs smooth without error message.

Yes! That fixed it (not sure why I didn't think to try that myself). Thanks much!
