Announcing the Chapel Hill Volume Rendering Test Dataset, Volume I
SoftLab Software Systems Laboratory

Chapel Hill, NC 27599-3175
The Chapel Hill Volume Rendering Test Dataset, Volume I is a collection of
the following seven data sets:
Head data - A 109-slice MRI data set of a human head. Complete
slices are stored consecutively as a 256 x 256 array. Pixels consist of 2
consecutive bytes making one binary integer. Data taken on the Siemens
Magnetom and provided courtesy of Siemens Medical Systems, Inc., Iselin, NJ.
Head data information article - An ascii file containing acknowledgements
for the head data files.
Knee data - A 127-slice MRI data set of a human knee. Complete
slices are stored consecutively as a 256 x 256 array. Pixels consist of
2 consecutive bytes making one binary integer. Data taken on the Siemens
Magnetom and provided courtesy of Siemens Medical Systems, Inc., Iselin, NJ.
Knee data information article - An ascii file containing acknowledgements
for the knee data files.
HIPIP data - The result of a quantum mechanical calculation of a SOD
data of a one-electron orbital of HIPIP, an iron protein. This
is an ascii data set. Provided courtesy of Louis Noodleman and David Case,
Scripps Clinic, La Jolla, CA.
HIPIP information article - An ascii file containing information
about the HIPIP data.
SOD data - An electron density map of the active site of
SOD (superoxide dismutase). This is an ascii data set. Provided courtesy
of Duncan McRee, Scripps Clinic, La Jolla, CA.
SOD histogram - An ascii histogram of the SOD data set. This
is described in the previous file.
SOD information article - An ascii file containing information
about the SOD data set.
The datasets were written on a Digital Equipment Corporation (DEC) VAX
computer. Each file contains only pixels, stored in row major order
with 2-byte integers per pixel. To use the images on machines that have
normal byte order (DECs use reverse byte order), you should swap alternate
bytes, for example using the 'dd' command in UNIX.
We do not object to your further distributing these datasets, but we
request that full acknowledgement of the source of the data accompany
such distribution. If you are going to send a dataset to someone, please
also send the accompanying information file.
For customers interested in purchasing the datasets on tape, both
Volume I and Volume II can be purchased for $50.00 each, or
$90.00 as a set. The distribution is available in two different
formats. The files on the tape will be written from a DEC VAX
computer using the UNIX file copy command 'dd' or the UNIX 'tar'
command. Total block size is 8192 bytes written at 1600 bpi on
either a standard 1/2" magnetic tape or a cartridge tape.
Please specify your preference when ordering and note that 'dd' is
not available with the cartridge tape. Installation instructions
accompany the distribution.
**We do not provide any software for displaying this data.
We ask that you report any problems or enhancement to the
address below.
