NAME

       teem  -  simple command-line tools which provide fast and easy access to the functionality
       in the various libraries

DESCRIPTION

       teem-affine: This uses air's AIR_AFFINE macro to print out the value which stands  in  the
       same  relationship with the interval [<minOut>, <maxOut>] as <value> has with the interval
       [minIn, maxOut].

       teem-deconv: Does deconvolution.

       teem-airSanity:

       teem-cubic:

       teem-emap: Creates environment maps based on limn's "checker" normal quantization methods.
       By  taking  into  account camera parameters, this allows for both lights in both world and
       view space. Solely out of laziness, the nrrd format is used for specifying the lights, but
       not to worry: you can use a simple un-adorned text file, defining one light per line, with
       7 values per light: 0/1 (world/view space), R G B color, and X Y Z position.

       teem-gkms: Semi-Automatic Generation of Transfer Functions

       teem-idx2pos: Converts from floating-point "index" to floating-point "position", given the
       centering of the data (cell vs. node), the range of positions, and the number of intervals
       into which position has been quantized.

       teem-ilk: (I)mage  (L)inear  Trans(X-->K)forms.  Applies  linear  (homogenous  coordinate)
       transforms to a given image, using the given kernel for resampling.

       teem-miter: A simple but effective little volume renderer.

       teem-mrender: A demonstration of hoover, gage, and nrrd measures. Uses hoover to cast rays
       through a volume (scalar, vector, or tensor), gage to measure one  of  various  quantities
       along  the rays, and a specified nrrd measure to reduce all the values along a ray down to
       one scalar, which is saved in the output (double) image.

       teem-ninspect: Quick way of seeing what's inside a 3D  volume.  A  color  image  of  three
       axis-aligned  projections  is  composed of histogram-equalized and quantized images of the
       summation (red), variance (green), and maximum (blue) intensity projections. If volume  is
       orientation  in  RAS  space,  then  a  standard  orientation  is  used for projections and
       projections are upsampled (with box kernel) to have isotropic pixels.

       teem-nrrdSanity:

       teem-overrgb: Composites an RGBA nrrd over a background  color  (or  image),  after  doing
       gamma correction, then quantizes to an 8-bit image. Actually, the input nrrd can have more
       than 4 values per pixel, but only the first four are used.  If the RGBA nrrd  is  floating
       point, the values are taken at face value; if it is fixed point, the values interpreted as
       having been quantized (so that 8-bit RGBA images will act as you expect). When compositing
       with  a  background image, the given background image does not have to be the same size as
       the input image; it will be resampled (with linear interpolation) to fit.

       teem-pos2idx: Converts from floating-point "position" to floating-point "index", given the
       centering of the data (cell vs. node), the range of positions, and the number of intervals
       into which position has been quantized.

       teem-pprobe: Uses gageProbe() to  query  scalar  or  vector  volumes  at  a  single  probe
       location.

       teem-qbert:  Generates  volume  datasets friendly to hardware-based volume renderers.  The
       main value of this is a means of combining the functions of  resampling  a  dataset  to  a
       particular  size,  measuring  first  (and  optionally  second) derivatives, and doing some
       semi-intelligent quantization of the derivative values down to 8-bits (if quantization  is
       desired).  The  various  up and down sampling, as well as the the VGH measurements, can be
       done with various nrrd kernels. Also, histogram-equalized VG and VH  scatterplots  can  be
       generated at a specified resolution.

       teem-talkweb: Generates HTML pages from slide images and text. This program takes multiple
       inputs: a template for the table of contents  that  will  become  "index.html"  ("-i"),  a
       template for the pages generated for each slide e.g.  "slide000.html" ("-t"), and a script
       text file that contains all the information that will go into the slide pages. The  format
       of this file is:
         - Separator line indicating slide transitions, e.g. "-------------"
         - Title of first slide (one line)
         - Filename for image to put on first slide (one line)
         - Body of HTML text to put with the slide image (multiple lines)
         -  Separator  followed  by  information  for  the  second  slide,  and so forth. Textual
       subtitutions are performed in the template files, according to the replacement tags ("-r",
       see  below). Within the slide pages, navigation arrows are based on remaining command-line
       options.

       teem-tend: Diffusion Tensor Processing and Analysis

       teem-undos undos: Converts from DOS text files to normal (converting LF-CR pairs  to  just
       CR),  or,  with the "-r" option, convert back to DOS, for whatever sick and twisted reason
       you'd have to do that. Can also handle legacy MAC text files (only LF). Unlike the  simple
       sed or perl scripts for this purpose, this program is careful to be idempotent. Also, this
       makes an effort to not meddle with binary files (on which this may be mistakenly invoked).
       A message is printed to stderr for all the files actually modified.

       teem-ungantry:  Gantry  tilt  be gone! This program is actually of limited utility: it can
       only change the tilt by shearing with the X and Z axis fixed, by some angle "around" the X
       axis, assuming that (X,Y,Z) is a right-handed frame.

       teem-unu: Utah Nrrd Utilities command-line interface

       teem-vprobe:  Shows  off  the functionality of the gage library. 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.
