I ran the tutorial https://mrtrix.readthedocs.io/en/latest/fixel_based_analysis/mt_fibre_density_cross-section.html up to point 20 " Reduce biases in tractogram densities " using HCP data, and have warped an anatomical mask with ROIs to standard space so that it has the same intensity value as T1 (obtained from HCP data), and computed a template mask with the ROIs.
So I next wanted to output a connectome assignment of each streamline using tck2connectome tracks_2_million_sift.tck association_template_mask.mif connectome.csv -out_assignment assign_connectome.csv
connectome2tck -keep_self tracks_2_million_sift.tck assign_connectome.csv connec
The problem is that the size of the output “connec” is only 692bytes and when I try to view it on mrview the tracts do not show. I tried to output this connectome using my MacBook Pro with 8GB of RAM, however when I ran it on another computer the file size was bigger and the tracts could be viewed on mrview. Is there any potential answer as to why it cannot show on my device?
