Morning, @rhonaldjr & welcome!
It sounds very surprising that uncompressed RAW should give you any problems. Usually, it is the compressed ones that can be tricky.
Which OS/distro do you use? Version?
What version of Rawtherapee?
Can you upload a sample image using https://filebin.net/ and post the resulting link here?
Have fun!

Oh, I was just trying to help! 
thanks, works. but it doesn’t detect the x-t3 (white balance is fine) camera (e.g. when applying lens correction)
Lens correction is handled via the lensfun library/project. I wouldn’t be surprised if the X-T3 isn’t in there yet, but you can make the measurements yourself to correct your lenses. Or from the terminal run lensfun-update-data (I think!).
the database is up-to-date. running lensfun-update-data returns No newer database was found for last installed Lensfun .
So I am assuming there is no much for X-T3 yet. At the moment I choose X-T2 for lens correction.
Indeed, I don’t see the X-T3 in this file: lensfun/mil-fujifilm.xml at master · lensfun/lensfun · GitHub
Morning, @rhonaldjr,
Thanks for the upload.
Brrr. Looks cold. Canada?
Your raf opens just fine in RawTherapee as well as in darktable.
True that rt/lensfun does not recognize X-T3 (yet),
but dt handles profiled noise profile fine.
I use the most updated git versions of rt and dt.
Have fun!

@Claes yes, it’s Canada and it’s -20 already (today). The RAF opens find in the latest darktable (link provided by @darix ) but there is no lensfun database update for it.
At least now I can work on the RAF images.
About to buy a Fujifilm GFX 50S (a weeks’ time to bite the bullet). Is it supported?
@LebedevRI thanks, instead bought the camera (checked in the documentation that basic things are supported w.r.t GFX 50S) and tested it.
Except the lens correction, everything else is fine.
