Manage Docker as a non-root user

I hope you mean that you used sudo to run fmriprep-docker, is that correct?

My apologies for not clarifying things. I used 'sudo docker run fmriprep ’ instead, as sudo fmriprep-docker is not a valid command.

Hi @Shengjie_Xu,

What you are reporting is a consequence of the defaults when you install Docker (i.e., it doesn’t have to do with fmriprep or fmriprep-docker). Please have a look to their documentation if you want to be able to run docker as a non-root user (which is highly recommended).

Incidentally, following up the guide will allow you to use the fmriprep-docker command.
