Diffusion image processing and analysis
"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 {\tt tend} tool part of the {\tt Teem} toolkit available at {\tt $<$http://teem.sf.net$>$}"
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.
