PAGE INFORMATION
The Background Pattern
The page background is repeatedly filled with a portion of the
collagen fiber diffraction pattern which is shown towards the
bottom of the page. The part used for the background is outside the
region shown. This has been saved as a compressed JPEG file using
lossy compression which results in a loss of definition and a more
blurred pattern. This is intended. The resulting file is 1284 bytes
in size, so it should not slow down the page loading. The aim
is to use a genuine crystallographic image as the backdrop, but of course
it musn't be too intrusive. Hence the black to dark purple color
scale.
The IUCr and CIF Logos
The imgCIF / CBF group has been working closely with the IUCr
COMCIFS committe and other CIF groups with the aim of CBF being
recognized by the IUCr in the same fashion as CIF. The logos are
used with the permission and indeed encouragement of the IUCr
COMCIFS committee.
The Quotation from Einstein
Arguably, the web page is not as simple as it might be, and this is
slightly touch in cheek, but the quote is not. Einstein's quote
sums up nicely Occam's razor, and one of the aims of the CBF format:
simplicity. In doing so, it balances the often conflicting need for
functionality with that of simplicity.
The Images
These images have been added to brighten up the page, and to remind
us of the name of the game. JPEG lossy compression has been used, but
to a lesser extent than with the background image, so as to preserve
quality. The file sizes are: 26377, 38698, and 27301 bytes, so they
may slow down the page loading a bit.
PTA Stained Collagen
This data was collected by Tim Wess and Linda Wess (Stirling University,
previously at Edinburgh University) on Station 7.2 at the Daresbury
Synchrotron Radiation Source. I was involved in the data analysis of
this and similar data. The fiber diffraction pattern has intermediate
ordering compared to the powder and single crystal patterns.
Olivine
This data was collected by Andy Fitch (ESRF) on the Swiss Norwegian
beam-line at the ESRF.
Protein X
Protein X (I've forgotten what the sample was) was collected by
Andy Thompson (EMBL-Grenoble) and collaboraters on BM-14 at the ESRF.
