teem-tend - Diffusion Image Processing and Analysis DESCRIPTION
"tend" is a command-line interface to much of the functionality in "ten", a C library for diffusion image processing. Ten is one library in the "Teem" collection of libraries. More information about Teem is at <http://teem.sourceforge.net>. Users are strongly encouraged to join the teem-users mailing list: <http://lists.sourceforge.net/lists/listinfo/teem-users>. This is the primary forum for feedback, questions, and feature requests. Like "unu", another Teem command-line binary, it is often useful to chain together invocations of tend with pipes, as in the following, which estimates tensors from DWIs, takes a slice of the tensor volume, computes the standard RGB colormap of the principal eigenvector, and then quantizes it to an 8-bit PNG: tend estim -i dwi.nhdr -B kvp -knownB0 true | tend slice -a 2 -p 30 | tend evecrgb -c 0 -a cl2 -gam 1.2 | unu quantize -b 8 -min 0 -max 1 -o z30-rgb.png If tend repeatedly proves itself useful for your research, an acknowledgment to that effect in your publication would be greatly appreciated, such as (for LaTeX): "Dataset processing performed with the { t tend} tool part of the { t Teem} toolkit available at { t $<$http://teem.sf.net$>$}" SEE ALSO
The full documentation for Teem is maintained as a Texinfo manual. If the info and teem-tend programs are properly installed at your site, the command info teem-tend should give you access to the complete manual. 1.10.0 December 10, 2008 teem-tend(1)

teem-vprobe(1) User Commands teem-vprobe(1) 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. sclY sxlZ>] [-k00 <kern00>] [-k11 <kern11>] [-k22 <kern22>] [-seed <N>] [-ssn <SS #>] [-ssr <scale range>] [-sss <scale save path>] [-ssw <SS pos>] [-kssblur <kernel>] [-kss <kernel>] [-ssrn <ssrn>] [-ssu] [-rn] [-gmc <min gradmag>] [-t <type>] [-o <nout>] -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: "-" SEE ALSO
