tend anvol -a <aniso> [-t <thresh>] [-i <nin>] [-o <nout>]

Apply an anisotropy metric to a DT volume. The anisotropy value will be zero in the locations which don’t meet the given confidence threshold.

-a <aniso>

Which anisotropy metric to plot. All the Westin metrics come in two versions. Currently supported:

• “cl1”, “cl2”: Westin’s linear
• “cp1”, “cp2”: Westin’s planar
• “ca1”, “ca2”: Westin’s linear + planar
• “cs1”, “cs2”: Westin’s spherical
• “ct1”, “ct2”: GK’s anisotropy type (cp/ca)
• “ra”: Basser/Pierpaoli relative anisotropy/sqrt(2)
• “fa”: Basser/Pierpaoli fractional anisotropy
• “vf”: volume fraction = 1-(Basser/Pierpaoli volume ratio)
• “tr”: trace

-t <thresh>

confidence threshold (float) default: “0.5”

-i <nin>

input diffusion tensor volume; default: “-”

-o <nout>

output image (floating point) (string) default: “-”

tend(1)

tend(1), tend-fiber(1).
