Hi Jean-Luc, That error message suggests that you downloaded the file as a web page, rather than as a raw text file. If you ask github to show you the raw file, then you can download it. I think the scripts are normally in /usr/share/darktable/tools or something like that. That is of course for

Filmic assumes that it receives a linear scene-referred image. darktable's standard matrices are just linear transformations of the demosaiced raw file, so this is fine. However, if you use an input profile that has some sort of gamma correction, then the data is no longer linear, and you can use
