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. 1.10.0 December 10, 2008 teem-tend(1)

NAME
teem-overrgb - Composites an RGBA nrrd over a background color. SYNOPSIS
teem-overrgb -i <nin> [-c <contrast>] [-cfp <fixed point>] fR DESCRIPTION
./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. [-g <gamma>] [-b <background>] [-bi <nbg>] -o <filename> -i <nin> = input nrrd to composite (nrrd) -c <contrast> = contrast to apply to RGB values, before gamma. "0.0" means no change, "1.0" means thresholding, "-1.0" means a complete washout. (double); default: "0.0" -cfp <fixed point> = component level that doesn't change with contrast (double); default: "0.5" -g <gamma> = gamma to apply to image data, after contrast (double); default: "1.0" -b <background> = background color to composite against; white is 1 1 1, not 255 255 255. (3 doubles); default: "0 0 0" -bi <nbg> = 8-bit RGB background image to composite against (nrrd); default: "" -o <filename> = file to write output PPM image to (string) SEE ALSO
