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 his-
       togram-equalized and quantized images of the summation (red), variance (green), and maximum (blue) intensity projections. If volume is ori-
       entation in RAS space, then a standard orientation is used for projections and projections are upsampled (with box kernel) to have isotrop-
       ic pixels.

       ic 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-intelli-
       gent 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 speci-
       fied 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, accord-
       ing 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.
