Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
DO A VECTOR OPERATION ON METRIC FILES
wb_command -metric-vector-operation
<vectors-a> - first vector input file
<vectors-b> - second vector input file
<operation> - what vector operation to do
<metric-out> - output - the output file
[-normalize-a] - normalize vectors of first input
[-normalize-b] - normalize vectors of second input
[-normalize-output] - normalize output vectors (not valid for dot
product)
[-magnitude] - output the magnitude of the result (not valid for dot
product)
Does a vector operation on two metric files (that must have a multiple of
3 columns). Either of the inputs may have multiple vectors (more than 3
columns), but not both (at least one must have exactly 3 columns). The
-magnitude and -normalize-output options may not be specified together,
or with an operation that returns a scalar (dot product). The
<operation> parameter must be one of the following:
DOT
CROSS
ADD
SUBTRACT
