The used badpixels file is not found, even though the filename is correct. It’s in the dark frame directory. The dark frame function with raw files works without problems. I have a Fujifilm X-T1.
I solved the problem. Somehow RT can’t read the badpixels file, if it is “saved as” with the notepad. I copied the RT options file into the dark frame directory, deleted the content and put in the bad pixels coordinates and “saved” it. Afterwards I changed the filename with the file explorer, somehow this way it doesn’t become a txt-file and RT can read it.
