Hi,

I am trying to use the atlas of 80 bundles you distribute here https://figshare.com/articles/Advanced_Atlas_of_80_Bundles_in_MNI_space/737588, but I am encountering some issues.

It is written that the files are in MNI space ICBM 2009a, which has affine equal to

array([[   1.,    0.,    0.,  -98.],
       [   0.,    1.,    0., -134.],
       [   0.,    0.,    1.,  -72.],
       [   0.,    0.,    0.,    1.]])

However, all the trk files have affine equal to the identity matrix. Is there a reason why you stored in the header of the trk files the identity matrix? This for example prevents their correct visualization in TrackVis. 

Another question: the file whole_brain_MNI.trk, besides having the same issue with the affine, has 144678 streamlines. Is it the same whole brain tractogram Yeh is referring to in their paper? In that paper they obtained a tractogram of 550000 streamlines. Or is it maybe the union of the 80 bundles?

Thank you a lot for your help,

best regards,

Giulia
