After trying the example bids app (which worked fine), I am trying the freesurfer bids app:

https://github.com/BIDS-Apps/freesurfer

I have built the docker container on my mac and I have the ds005 data directory here and the license.txt which I requested from freesurfer. I asked for a linux license (assuming the container contains linux and that was the relevant fact).

dpat@Saci:/Volumes/Main/Working/BIDS_TESTING% docker run -ti --rm -v /Volumes/Main/Working/BIDS_TESTING/ds005:/bids_dataset:ro -v /Volumes/Main/Working/BIDS_TESTING/outputs:/outputs bids/freesurfer /bids_dataset /outputs participant --license_file "license.txt" 1: You should define 'SliceTiming' for this file. If you don't provide this information slice time correction will not be possible.

Summary: Available Tasks: Available Modalities: 133 Files, 1.77GB mixed-gambles task T1w 16 - Subjects inplaneT2 1 - Session bold

Traceback (most recent call last): File "/run.py", line 165, in <module> raise Exception("Provided license file does not exist") *Exception: Provided license file does not exist* =========== If I provide the full path to the license file, it still fails:

docker run -ti --rm -v /Volumes/Main/Working/BIDS_TESTING/ds005:/bids_dataset:ro -v /Volumes/Main/Working/BIDS_TESTING/outputs:/outputs bids/freesurfer /bids_dataset /outputs participant --license_file "/Volumes/Main/Working/BIDS_ TESTING/license.txt"

Suggestions? How do I tell freesurfer where the license file is?

Thanks so much,
