Hi @neurobiffie,
I’ll also note that more up-to-date minimal preprocessing with fMRIPrep has been done, and can be accessed via AWS S3 at fcp-indi/data/Projects/ADHD200/Outputs/fmriprep/fmriprep/. Using these outputs you can have more flexibility with how denoising and postprocessing is done, if that is of interest to you.
So you can copy the data with something like aws s3 cp -r fcp-indi/data/Projects/ADHD200/Outputs/fmriprep/fmriprep/ /path/to/local/. This requires you to install the AWS command line interface.
Best,
Steven
