OpenNeuro derivatives bucket

1

Hello! We are trying to use ds000030 and particularly, the derivatives described here: OpenNeuro.

However, this command:

aws s3 ls s3://openneuro-derivatives/ --no-sign-request

raises:

An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied

Same thing if I run:

aws s3 ls --no-sign-request s3://openneuro-derivatives/mriqc/ds000030-mriqc

This is surprising, because I expected this to be an openly accesible bucket. Is this bucket mis-configured? Or maybe the instructions on Open Neuro are out-of-date? Thanks!

Hi @Ariel_Rokem,

Try the following, as detailed in the comments section of the original dataset.

aws s3 ls --no-sign-request s3://openneuro/ds000030/ds000030_R1.0.5/uncompressed/derivatives/ 
                           PRE fmriprep/
                           PRE freesurfer/
                           PRE mriqc/
                           PRE parameter_plots/
                           PRE physio_plots/
                           PRE task/
                           PRE task_group/

Best,
Steven

Hey Steven - thanks! That got us unstuck.

I wonder how one would get qsiprep derivatives we just produced in there as well :slight_smile:

Hi Ariel, thanks for bringing up this issue. There was a problem with the bucket permissions that should be fixed now. Let me know if you still have issues downloading from s3://openneuro-derivatives/.

Also, we might be able to host the qsiprep derivatives - let me get back to you on that.

Thanks,
Joe
