9. Understanding the file formats
Velocity
Discontinued as of CellexalVR 0.13.0. The data is now in the graph files.
The .velo files contain velocity information. A velocity file must be named the same as a .mds file because velocity information is tied to a graph. E.g. velocity information for a graph defined in tsne.mds must be inside a file named tsne.velo. The velocity files have the following file format:
cell_1 | x_from | y_from | z_from | x_to | y_to | z_to |
cell_2 | x_from | y_from | z_from | x_to | y_to | z_to |
... |
Where each cell_x is a cell that is defined in the corresponding .mds file, each x_from, y_from and z_from are the x, y and z coordinates that the velocities start from. Each x_to, y_to and z_to are the x, y and z coordinates where the velocities are pointing to. All coordinates in your .velo files must be in the same coordinate bases as your corresponding .mds files.
