dcraw to Arri Log C Arri Wide Gamut

Hello everybody,

because ptgui has massive issues with stitching linear tiffs (I tried aces etc. https://i.imgur.com/yVMUFsi.jpg) I would like to debayer my raws directly into Arri LogC Wide gamut. Can someone help me with setting that up as I am fairly inexperienced with such color science issues?
