Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
COMPUTE DOT PRODUCTS OF FIBER ORIENTATIONS WITH SURFACE NORMALS
wb_command -fiber-dot-products
<white-surf> - the white/gray boundary surface
<fiber-file> - the fiber orientation file
<max-dist> - the maximum distance from any surface vertex a fiber
population may be, in mm
<direction> - test against surface for whether a fiber population should
be used
<dot-metric> - output - the metric of dot products
<f-metric> - output - a metric of the f values of the fiber distributions
For each vertex, this command finds the closest fiber population that
satisfies the <direction> test, and computes the absolute value of the
dot product of the surface normal and the normalized mean direction of
each fiber. The <direction> test must be one of INSIDE, OUTSIDE, or ANY,
which causes the command to only use fiber populations that are inside
the surface, outside the surface, or to not care which direction it is
from the surface. Each fiber population is output in a separate metric
column.
