Problems with download methods regarding ds001226 on openneuro


I found a couple of errors trying to download dataset ds001226 and derivatives on openneuro.

1- About the dataset itself, it has a “derivatives” folder in it. If you download it using the datalad method this folder is missing (the other folders are not). If you use aws s3 it has the “derivatives” folder but is not complete, it only have subfolders “mriqc” and “TVB”. If you use script method “derivative” folder seems complete. Didn’t try with Node.js method.

2- Regarding derivatives datasets ds001226-mriqc and ds001226-fmriprep you get a permission error while using aws s3 sync --no-sign-request:

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

Datalad method was OK for ds001226-fmriprep (didn’t try yet ds001226-mriqc).
