NAME

       teem-vprobe - Shows off the functionality of the gage library.

SYNOPSIS

       teem-vprobe -i <nin> -k <kind> [-v <verbosity>] -q <query> [-s <sclX fR

DESCRIPTION

       Uses  gageProbe()  to  query  various  kinds  of  volumes  to  learn  various  measured or derived quantities. Can set environment variable
       TEEM_VPROBE_HACK_ZI to limit probing to a single z slice.

	      -i <nin> = input volume

	      -k <kind> = "kind" of volume ("scalar", "vector", "tensor", or

	      "dwi")

       -v <verbosity> = verbosity level (int); default: "1"

	      -q <query> = the quantity (scalar, vector, or matrix) to learn by

	      probing (string)

       -s <sclX sclY sxlZ> = scaling factor for resampling on each axis (>1.0 :
	      supersampling) (3 doubles); default: "1.0 1.0 1.0"

       -k00 <kern00> = kernel for gageKernel00; default: "tent"

       -k11 <kern11> = kernel for gageKernel11; default: "cubicd:1,0"

       -k22 <kern22> = kernel for gageKernel22; default: "cubicdd:1,0"

	      -seed <N> = RNG seed; mostly for debugging (unsigned int);

	      default: "42"

	      -ssn <SS #> = how many scale-space samples to evaluate, or, 0 to

	      turn-off all scale-space behavior (unsigned int); default: "0"

       -ssr <scale range> = range of scales in scale-space (2 doubles);
	      default: "nan nan"

       -sss <scale save path> = give a non-empty path string (like "./") to save out

	      the pre-blurred volumes computed for the stack (string); default: ""

       -ssw <SS pos> = "world"-space position (true sigma) at which to
	      sample in scale-space (double); default: "0"

       -kssblur <kernel> = blurring kernel, to sample scale space;
	      default: "dgauss:1,5"

       -kss <kernel> = kernel for reconstructing from scale space samples;
	      default: "tent"

       -ssrn <ssrn> = enable derivative normalization based on scale space
	      (int); default: "0"

	      -ssu = do uniform samples along sigma, and not (by default)

	      samples according to the logarithm of diffusion time

	      -rn = renormalize kernel weights at each new sample

	      location. "Accurate" kernels don't need this; doing it always makes things go slower

       -gmc <min gradmag> = For curvature-based queries, use zero when gradient
	      magnitude is below this (double); default: "0.0"

	      -t <type> = type of output volume (type); default: "float" -o <nout> = output volume (string); default: "-"
