Canon 60D Bayer Matrix confusion

[StevePD]

I new to PI and I THINK I'm just beginning to get to grips with it. However, confusion now reigns. I use a Canon 60D DSLR, and everything I have ever read says that the Bayer matrix for this and other Canons is RGGB. However, I've been getting some funny purple casts on my images, so I tried putting in an 'ordinary' photo of some flowers in RAW CR2 format. The process console reported that the CFA pattern for the photo was GBRG, and indeed if I debayered it using GBRG the output is correctly coloured. If I try debayering using RGGB I get the purple cast.

In Format Explorer, under RAW, I have selected Pure RAW.

Have I totally missed the point on any aspect of this?

Thanks for any help

Pixinsight uses LibRaw as raw decoding software. LibRaw changed the way in which raw images are cropped. This led to the change of the bayer pattern. Please read the following thread: https://pixinsight.com/forum/index....rd-in-images-after-batch-preprocessing.14272/ , especially posts #6 and #8.

Bottom line: use the Bayer pattern 'GBRG' or 'Auto' in PixInsight for this camera.
