The Visible Orbit site in the year 2020

It’s almost exactly 13 years since the very first entry on this site, the Visible Orbit blog.

I’ve just moved the whole site, including 50GB of high resolution orbita and embryo histology slices, to its new home on a server in Nuremburg.

Everything should feel slightly snappier and a little more fresh, but most importantly: All of the resources here are still available at the same locations for 13 years now, and things are looking good for the coming years.

Seven registered full-resolution sets available!

On our high-res section stacks page, you can now find seven fully registered stacks of our highest resolution scans of 4 orbits, 2 embryonic heads and 1 full embryo. All of the 1500 slices in these sets have been carefully registered (mapped, in this case by rotation and translation) onto each other using the fantastic TrakEM2 plugin of the Fiji ImageJ distribution.

Server upgrade!

Today this server was upgraded: Double the RAM, lots more disc space and RHEL 6.1. This also meant that we could finally upgrade to WordPress 3.2.1, and whilst we were at it we installed a brand new theme and tweaked the PHP setup for more speed.

With some help from the Edinburgh Mouse Atlas Project (EMAP), we also now have the Woolz IIP server running on an internal test machine on one of the orbita slice stacks. At the moment, more of our machines are crunching all off the stacks into pyramidal tiffs, and then well start moving theme here where they belong. This means youll be able to browse through all the stacks at full resolution, Google Maps style!

High-resolution sections available RSN(tm) via Woolz IIP image viewer

The source code to HistoVis, the client-server visualisation framework developed by Jeroen Verschuur, has been available online for some time now. However, between the technical challenges of getting it going on the aging Redhat installation on the Sun server at our disposal and general time-pressure, the system is not operational on the visible orbit data yet.

For this and other reasons, we have recently decided to make the high resolution slices available here via the Woolz IIP viewer software as soon as possible. Please bear with us as we get the gigabytes of data pre-processed and ready. At such time, you’ll be able to view any of the high-resolution slices in your browser. For an example, see the TS19 stack on the Woolz IIP viewer website.
