As I understand it, they are the fMRI images mapped to coordinates in the brain, but I'm having trouble understanding exactly how to use them. I haven't been successful in finding more detailed information about it on the HCP website, but I might simply not know the correct place to look. If anyone can point me in the correct direction, it would be much appreciated. Some context: I'm attempting to classify the actions done in the MOTOR task using various forms of neural networks. So far, I've tried using the sequences of fMRI data (the 284x91x109x91 .nii files), but have not achieved better than random classification accuracy. A colleague told me that the *_Atlas.dtseries.nii files contained the fMRI data mapped to a 2D atlas, which would enable me to do 2D convolution without losing information (as I would by e.g. collapsing the 3D images to 2D by taking the mean of a direction). Thank you for the attention.
