Most likely. Please add an issue in Github!

I guess that sft_atlas = load_trk(atlas_file, "same", bbox_valid_check=False) needs a reference rather that "same".Thank you.best,GiuliaOn Thu, Nov 21, 2019 at 6:30 PM Eleftherios Garyfallidis <elef@indiana.edu> wrote:Yes, you can correct the affine by using the StatefulTractogram and the affine of the data that generated the tracks or the original tractogramOn Thu, Nov 21, 2019 at 12:28 PM Giulia Berto' <gberto@fbk.eu> wrote: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 toarray([[ 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
