Hello ,

I am new to Neuroimaging and ni want to persue research on ADHD 200 dataset for classification of ADHD/TD.

As we know that NITRC has made available preprocessed data from 8 different sites , i am having few doubts to start with.

1. Do we need to download data from all 8 sites or few site will work .

2. For a perticular site data, what files i need to download.

3. How to find the ground truth used in the project (e.g. dx = 0,1,2,3 , what is the catagory corresponding to 2 and 3 ).

4. In Testing Phenotype , almost all Dx are mentioned as "Withheld". From where to find this information.

5. How to know sequence /processing of different files .


Regards,
Deepika
