In order to bring the ADHD-200 Global Competition to a wider audience, The Neuro Bureau is making preprocessed versions of the competition data freely available to the general public (neurobureau.projects.nitrc.org/ADHD200). These openly downloadable datasets include both preprocessed versions of structural and functional dataset previously made available by the ADHD-200 consortium, as well as initial standard subject-level analyses (e.g., fractional amplitude of low frequency fluctuations, connectivity maps for 10 commonly observed resting state networks (Smith et al. PNAS 2009)). We hope this release will open collaborative possibilities and contributions from researchers not traditionally addressing brain data -- for those whose specialties lay outside of MRI and fMRI data processing, the competition is now one step easier. 

The preprocessing pipelines will include:
1) The Athena: resting state fMRI and voxel-based morphometry preprocessing (grey matter) using AFNI and FSL [released]

2) The Burner: voxel-based morphometry processing (grey matter and white matter) using 
DARTEL in SPM [coming soon]

3) The NIAK: resting state fMRI preprocessing using the NeuroImaging Analysis Kit on CBRAIN [coming soon]

4) The CIVET: cortical thickness measures extracted using the CIVET pipeline on CBRAIN [coming soon]

Additionally, for May 1, we anticipate the release of extracted timeseries data (in .csv format) and corresponding full- and partial-correlation matrices for a variety of brain parcellation schemes. 

For more information and to download data please visit: neurobureau.projects.nitrc.org/ADHD200. A NITRC account is required to download data.

Cheers,
Cameron Craddock, Daniel Margulies, and The Neuro Bureau

I apologize for the repeat posting.  The correct URL for the preprocessed data is neurobureau.projects.nitrc.org/ADHD200.

Hi all. First, thanks to INDI and the Neuro-Bureau for doing all this work. It makes a man hate to ask for more... but naturally I will anyway.

My teammates and I will likely use the Neuro-Bureau preprocessed data, and in light of that, we'd just as soon not have to download gigs and gigs of data we won't use from the project website. It's really slow going, and we're champing at the bit. Is it possible to release the corrected phenotypic data on its own, not bundled with the imaging data? Or is it already available somewhere that I haven't noticed?


Thanks again,
Matt

Hello Matt,

The preprocessed data includes the most up to data phenotypic data in the tar files, so you do not need to download the raw data.  Is this what you were asking?

Cheers,
Cameron

Hi Matt,

Thanks for your suggestion. I will make the phenotypic files available as individual downloads on the ADHD-200 website.

cheers,
Maarten

Ah, OK. That's what I wanted. I still think it would be useful in general to have the phenotypic data available as a separate download, and it looks like Maarten is on that... but for me, this is perfect. Thanks!

Phenotypic files are now also available as individual downloads for the ADHD-200 datasets on the ADHD-200 site.

Cheers,
Maarten

Thanks for your effort. After an attempt to manage by myself the whole preprocessing I'm turning to rely on the data released by Neuro-Bureau. Before to proceed I would like to understand what will happen at the beginning of July when the test data will be released. What is your plan for getting available the preprocessed test data according to the parameters applied to training data? How long will take to release the preprocessed test data? Do you support the preprocessing for all pipelines or only part of them? It seems to me that it is not known the size of test data, i.e. the number of subjects, and may be it is hard to estimate the required effort. Anyway, any news, good news.
Best regards.

Paolo

Hello Paolo,

Thank you for your interested in the ADHD200 preprocessed data.  Our intention is to get the data preprocessed and available withen a week of the release.  This is of course, our intention, and not a guarantee.  I also have no idea how big the the test dataset is, and just hope that I haven't overcommitted myself :).

Cheers,
Cameron

Dear 

Hello

I hope you are doing well.i am currently conducting a research project on ADHD and wpuld like to kindley request access to the preprocessed ADHD-200 dataset .if available these data would significantly support the methodological steps in my study ,particulary in fnctional  connectivity and graph  -theoretical analysis .please let me know if there are any requirements or forums I need to complete for obtaining access.

 thank you for your time and assistance.

best regards

Dear 

I hope this message finds you well. I am currently conducting a research project focused on ADHD, and I would like to kindly request access to the preprocessed ADHD-200 dataset.

Specifically, I am interested in obtaining the preprocessed resting-state fMRI ROI time series data based on the AAL atlas. These ROI-level time series would be highly valuable for the methodological components of my study, particularly for functional connectivity analysis and graph-theoretical modeling.

I would be grateful if you could let me know whether these AAL-based fMRI time series are available, and if so, whether there are any requirements, forms, or data usage agreements that need to be completed in order to obtain access.

Thank you very much for your time and consideration. I look forward to your response.

Kind regards,
Zhao Zheng
