Is Nik Collection by DxO compatible with DxO PureRAW, can I directly export files from DxO PureRAW into Nik Collection by DxO?

This information applies to version(s): 2018, 2, 3, 4

Nik Collection was never designed to be compatible with RAW files, so to use Nik Collection with images processed through DxO PureRAW, the exported file will need to be a JPEG.
