Just as an example, here I’m mounting my existing MNI152NLin6Asym directory into the Docker image:
$ docker run --rm -it \
-v /home/chris/.cache/templateflow/tpl-MNI152NLin6Asym:/home/fmriprep/.cache/templateflow/tpl-MNI152NLin6Asym3mm \
--entrypoint=bash nipreps/fmriprep:22.1.1
(base) root@035e86989976:/tmp# ls -l /home/fmriprep/.cache/templateflow
total 236
