NAME

       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.
