The goal of mascot is to provide easy access to recent macroscale structural connectomes of the Human brain obtained from diffusion MRI data through diffusion modeling and subsequent so-called tractography.
Datasets
Currently, the package contains:
- the HCP-YA845 and HCP-YA1065 tractography atlases from Yeh FC, Panesar S, Fernandes D, Meola A, Yoshino M, Fernandez-Miranda JC, Vettel JM, Verstynen T. Population-averaged atlas of the macroscale human structural connectome and its network topology. Neuroimage. 2018 Sep 1;178:57-68 (2021 update).
Each white matter fascicle comes in the form of a tibble in which each row is a point characterized by the following five variables:
-
X,Y,Z: 3D coordinates of the current point; -
PointId: Identification number of the current point among all points of the streamline it belongs to; -
StreamlineId: Identification number of the streamline which the current point belongs to.
Installation
