Tractostorm 2: Optimizing tractography dissection reproducibility with segmentation protocol dissemination

Submissions for the Tractostorm 2 Project [1]  from our collaborators (raters) are available for new analysis.
Contains regions of interest (ROIs) as well as resulting bundles. Segmentations were performed with MI-Brain [2] (MI-Brain)

Initial data is the same as in the initial Tractostorm Project [3]
Contains the data as sent to collaborators and the written document containing the dissection protocol in detail.

Data Organization:
The 5 HCP subjects were duplicated 4 times each.
193441 -> A111, B218, C317, D418
219231 -> A127, B228, C320, D426
286650 -> A136, B237, C338, D436
486759 -> A149, B246, C344, D443
615441 -> A156, B252, C359, D450

Bundles can be segmented automatically using the scilpy toolbox.
scil_filter_tractogram.py ${INPUT} ${OUTPUT} ${OPTIONS}

• ${INPUT} would be the whole brain tractogram of an HCP subject in data_to_segment.zip
• ${OUTPUT} would be the bundle filename (preferably .trk format)
• ${OPTIONS} would be the sequence of ROIs to apply, one for each bundle.
