Hello ,

I am new to Neuroimaging and i want to pursue research on ADHD 200 datasets 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 particular site data, what all 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 category corresponding to 2 and 3 ).
4. How to know sequence /processing of different files .



Regards,
Deepika
