Processed Mouse Vessel Locations from A hydraulic resistance model for interstitial fluid flow in the brain

The data from Blinder et al. are provided as a series of points distributed along the centerlines of the vessels. Though penetrating venules and ascending veins are primarily oriented perpendicular to the cortical surface (along the z direction), they occasionally deviate from that orientation and intersect a cross-section at a particular depth more than once. In those cases, we “filter” the data by including only the midpoint of the intersections. Both the filtered and the unfiltered data are provided as Supplemental Material in the accompanying MATLAB file, “Blinder_Coordinates.mat”, where mouse 1, mouse 2, mouse 3, and mouse 4 are labeled “au”, “co”, “db”, and “av”, respectively. Each mouse has a set of coordinates for arterioles (“art”) and venules (“ven”) where columns 1, 2, and 3 correspond to X, Y, and Z coordinates. The substructure “originalstrands” contains the vessel strand index for each of the points in the coordinate set.
