SYNOPSIS

       teem-gprobe -i <nin> -k <kind> [-v <verbosity>] -q <query> \fR

DESCRIPTION

       ./teem-gprobe:  Shows off the functionality of the gage library. Uses gageProbe() to query
       various kinds of volumes to learn various measured or derived quantities.

              -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)

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

              -ofs = If only per-axis spacing is available, use that

              to contrive full orientation info

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

              default: "42"

              -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"

              -rn = renormalize kernel weights at each new sample

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

              -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"

              -kssb <kernel> = blurring kernel, to sample scale space;

              default: "dgauss:1,5"

              -kssr <kernel> = kernel for reconstructing from scale space

              samples; default: "hermite"

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

              default) samples according to the effective diffusion scale

              -sso = if not using "-ssu", use pre-computed optimal

              sigmas when possible

              -ssnd = normalize derivatives by scale

       -ssf <SS read/save format> = printf-style format (including a "%u") for the

              filenames  from  which  to read pre-blurred volumes computed for the stack, if they
              exist and match the stack parameters, and where to save them  if  they  had  to  be
              re-computed. Leave this as empty string to disable this. (string); default: ""

       -s <sclX sclY sxlZ> = scaling factor for resampling on each axis (>1.0
              :  supersampling);  use "-ssp" (and "-psi")to specify scale position of sampling (3
              doubles); default: "1 1 1"

              -ssp <pos> = when using scale-space, scale-position at which

              to probe (double); default: "0"

              -pg <nrrd> = overrides "-s": 2-D nrrd which specifies origin

              and direction vectors for sampling grid; default: ""

              -pi <nrrd> = overrides "-pv": probes at this list of 3-vec or

              4-vec positions; default: ""

              -pp <pos ...> = overrides "-pi": only sample at this specified

              point (3..4 doubles); default: "nan nan nan"

              -eps <epsilon> = if non-zero, and if query is a scalar, and if

              using "pp" to query at a single point, then do epsilon offset probes  to  calculate
              discrete  differences,  to  find the numerical gradient and hessian (for debugging)
              (double); default: "0"

              -psi <p> = whether the probe location specification (by any

              of the four previous flags) are in index space (bool); default: "true"

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