neurobureau:ADHDpreproc

From NITRC Wiki

Are you a mathematician with killer MVPA-skills? Due you have a vast knowledge of neuroimaging but lack the supercomputer to bring you the glory? Are you too busy pruning your mustache to bother with preprocessing? .... Finally, the ADHD200 Competition is yours to conquer!  

In order to bring the ADHD200 Competition to a wider audience, The Neuro Bureau is making preprocessed versions of the competition data freely available to the general public. These openly downloadable datasets include both preprocessed structural and functional data, as well as initial standard subject-level analyses. We hope this release will open collaborative possibilities and contributions from researchers not traditionally addressing brain data. So for those whose specialities lay outside of resting-state data analysis, the competition is now one step easier for you to enter. 

Full Disclosure & Disclaimer: While there is general consensus in terms of what preprocessing steps need to be performed, there is still much debate on the proper order of the steps, and specific parameter settings. We cannot guarantee that the preprocessing pipelines used here are the best, but they were constructed based on several years of expertise in MRI and fMRI analyses, and should be more than sufficient for subsequent analyses. We have setup the ADHD200preproc Forum for users to post questions and discuss issues related to the preprocessing.

In more legalistic terms: The preprocessed ADHD200 data is released without warranty and without the guarantee of support. In the interest of making this data available as quickly as possible, we have not performed quality control on the raw or preprocessed data. We are hoping that the community will help with this process, so please post your QC judgements to the user list so that others may benefit from your quality control efforts. We would also to be thrilled to make available further contributions of preprocessed data -- so please just get in touch if you'd like to generously offer some uploads to the community.

This data is being made freely available through efforts of the ADHD200 consortium as well as The Neuro Bureau. We kindly ask that you acknowledge both of these organizations in any publications (conference, journal, etc.) that make use of this data. None of the preprocessing would be possible without the freely available imaging analysis packages, so please also acknowledge the relevent packages and resources as well as any other specific release related acknowledgements (see links below).

List of available preprocessing strategies:

• The Athena: resting state fMRI and voxel based morphometry preprocessing (grey matter) using AFNI and FSL. Now includes extracted time courses, ReHo, and the Test Dataset! [released]
• The Burner: voxel based morphometry processing (grey matter and white matter) using DARTEL in SPM Now includes the preprocessed test dataset! [released]
• The NIAK: resting state fMRI preprocessing using the NeuroImaging Analysis Kit on CBRAIN ! [released]
• The CIVET: cortical thickness measures extracted using the CIVET pipeline on CBRAIN [release forthcoming]
