I tried to create a denoising profile for my Google Nexus-5 smartphone as described in a blog post. I shot some pictures, one per ISO setting (100,200,400,800,1600,3200) with OpenCamera which are under- and over-exposed. Then i tried to create the profile, but the script doesn't recognize the directory or the files in it.
~/nexus-5-iso-denoising$ ~/darktable/tools/noise/gen-profile -d .

Noise profiling requires at least a RAW image per required or supported
ISO setting.
Either:
o Plug your camera to this computer and, when detected, hit Return.
This script will query the camera for supported ISO settings and
take the appropriate images.
o Type Ctrl+C, take at least one image per supported ISO setting and
put them in a dedicated directory. Then, re-run this script and be
sure to indicate this directory by using the "-d" flag.
Important note about the required images:
o The subject must contain both under-exposed AND over-exposed
areas. A possible subject could be a sunny window (or an in-door
light) on half of the picture and a dark/shadowed in-door object on
the other half.
o Disable auto-focus and put everything out of focus.
Do I need a certain file format for the raw images or do I need to name the files in a certain way?
If it's helpful: I imported the *.dng raw files in darktable applied the raw linear style and exported the images as jpeg,ppm,pfm:
~/nexus-5-iso-denoising$ ls
