Starting fmriprep_docker


I’m new to fmriprep so as many others I followed the tutorials online to download and install fmriprep on a Windows 10 machine. Since I run into problems when installing via

python -m pip install --user --upgrade fmriprep-docker

I used
python -m pip install --upgrade fmriprep-docker

instead. I am Aware that the latter might cause Problems with dependencies, but I actually had Problems with dependencies when doing the former.

When I search for the .exe file, it can be found:
C:\Users\maditas>where fmriprep-docker

However, when I call the docker, I get the following (although being logged in to docker with my username, not my email):

C:\Users\maditas>fmriprep-docker C:\Users\alexs\lab\BIDStest C:\Users\maditas\lab\BIDStest\derivatives participant --participant-label sub-10206 --fs-license C:\Software\FreeSurfer\license.txt
Downloading. This may take a while…
Unable to find image ‘poldracklab/fmriprep:20.0.6’ locally
docker: Error response from daemon: Get unauthorized: incorrect username or password.
See ‘docker run --help’.
Could not detect memory capacity of Docker container.
Do you have permission to run docker?

Also, I increased Memory to 8 GB on the Hyper-V-Manager.

Am I missing anything? I’d appreciate any help.
Thank you very much!
