I have identified specific participant ID numbers from the behavioral data that I would like to download the imaging data for to conduct analysis. I have not found an immediate way to do this through NDA and was wondering if anyone had a suggestion of how to go about this. Thanks
I think you can use NDAtools (command line tool, https://github.com/NDAR/nda-tools). The downloadcmd have parameters about filter to specific which data you want to download.

Yes! The upcoming data exercise for ABCD-ReproNim Week 11 has a demo of how to use the nda-tools python package for downloading data. This guide is also pretty helpful for the packaging process! You can select specific participants as a filter for your data package by [querying by GUID] (https://nda.nih.gov/general-query.html?q=query=guids)
Hello, I would like to ask where I can get the package ID. For example, if I want to use NDA tools to download all behavioral data, what kind of file do I need? Do I need to create this file myself, or is there a specific variable that already has a fixed package ID?
Hi,
You can download the behavioral tabulated data directly from NDA without using NDA tools: NIMH Data Archive - Data - Study
It’s ~14 GB so direct download should be straightforward. If not, you need to create a package yourself – this guide is helpful: exercises/project_month_prep/downloadMRI.md at main · ABCD-ReproNim/exercises · GitHub
Mind you that NDA hasn’t been allowing packaging or downloading data since last week!
