Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
GENERATES A MATRIX2 CIFTI FROM MATRIX4 WBSPARSE
wb_command -convert-matrix4-to-matrix2
<matrix4-wbsparse> - a wbsparse matrix4 file
<counts-out> - output - the total fiber counts, as a cifti file
[-distances] - output average trajectory distance
<distance-out> - output - the distances, as a cifti file
[-individual-fibers] - output files for each fiber direction
<fiber-1> - output - output file for first fiber
<fiber-2> - output - output file for second fiber
<fiber-3> - output - output file for third fiber
This command makes a cifti file from the fiber counts in a matrix4
wbsparse file, and optionally a second cifti file from the distances.
Note that while the total count is stored exactly, the per-fiber counts
are stored as approximate fractions, so the output of -individual-fibers
will contain nonintegers.
