Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
CHANGE RADIUS AND OPTIONALLY RECENTER A SPHERE
wb_command -surface-modify-sphere
<sphere-in> - the sphere to modify
<radius> - the radius the output sphere should have
<sphere-out> - output - the output sphere
[-recenter] - recenter the sphere by means of the bounding box
This command may be useful if you have used -surface-resample to resample
a sphere, which can suffer from problems generally not present in
-surface-sphere-project-unproject. If the sphere should already be
centered around the origin, using -recenter may still shift it slightly
before changing the radius, which is likely to be undesireable.
If <sphere-in> is not close to spherical, or not centered around the
origin and -recenter is not used, a warning is printed.
