I have one bayer raw file which contains only pixel values in bayer pattern and no metadata.The bayer pattern is known.
Is it possible to the file using RawTherapee? The following link provides some information:
The information is not enough to solve my problem.

RawTherapee uses an embedded copy of the DCRAW utility to read and decode the RAW file (original source code). So, you need to add support for your file format here.

    \$\begingroup\$ The source code of DCRAW is pretty straightforward. You might be able to rewrite some parts to use configuration files, but I doubt that you can support all idiosyncrasies of all RAW formats in configuration, without writing most code twice: as source code and as configuration file. It is much easier to keep it all in one place, i.e in source code. \$\endgroup\$
