NAME

       teem-unu - Utah Nrrd Utilities command-line interface

DESCRIPTION

       "teem-unu" is a command-line interface to much of the functionality in "nrrd",

              a C library for raster data processing. Nrrd is one library in the "Teem" collection of libraries.
              More information about Teem is at <http://teem.sf.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.

              The utility of unu is mainly as a pre-processing tool for getting data

              into a type, encoding, format, or dimensions best suited for some visualization or rendering task.
              Also, slices and projections are effective ways to visually inspect the  contents  of  a  dataset.
              Especially  useful commands include make, resample, crop, slice, project, histo, dhisto, quantize,
              and save. Full documentation for each command is shown by typing the  command  alone,  e.g.,  "unu
              make".  Unu  can  process  CT  and  MRI  volume datasets, grayscale and color images, time-varying
              volumes of vector fields (5-D arrays), and more. Currently supported formats are plain text  files
              (2-D  float  arrays),  NRRD,  VTK structured points, and PNG and PNM images. "unu make -bs -1" can
              read from DICOM files. "unu save" can generate EPS files.  Supported  encodings  are  raw,  ascii,
              hex, gzip, and bzip2.

              Much of the functionality of unu derives from chaining multiple

              invocations  together  with  pipes  ("|"), minimizing the need to save out intermediate files. For
              example, if "data.raw.gz" is a gzip'ed 256 x 256 x 80 volume of raw floats written from a PC, then
              the following will save to "zsum.png" a histogram equalized summation projection along the slowest
              axis:

              unu make -i data.raw.gz -t float -s 256 256 80 -e gzip -en little \

              | unu project -a 2 -m sum \ | unu heq -b 2000 -s 1 \ | unu quantize -b 8 -o zsum.png

              If unu or nrrd 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 {\tt unu} tool (or the {\tt nrrd} library), part of
              the {\tt Teem} toolkit available at {\tt $<$http://teem.sf.net$>$}"

              Formats available: nrrd pnm png vtk text eps Nrrd data encodings available: raw ascii hex gz bz2

       The full documentation for teem-unu is maintained as a Texinfo manual.  If the info and teem-unu programs
       are properly installed at your site, the command

              info teem-unu

       should give you access to the complete manual.
