# teem-vprobe(1)

Shows off the functionality of the gage library.

## 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: "-"
