Info

Slither
is an application designed to track the movement of C. elegans worms in
a laboratory environment. You can either use video footage you've
already captured from your dissection microscope camera, or you can
allow Slither to capture new footage for you. If you're curious how the
detection algorithm works, you can read about it informally here.
It was being developed by Kip
Warner under the Small Neural Systems Group of Dr. Catharine
Rankin, at the Brain Research Centre located at the
University
of British Columbia.
Slither is released under the
GNU General Public License and is available for GNU, Windows, and
OS X. Accessibility is important, and thus porting to other operating
systems is encouraged.
A mailing list for both development and user discussion is available here.

Released Ubuntu i386
package and OS X (universal) for
0.0.45.
- Updated:
OS X users can now use Slither under Leopard. However, due to problems
with Apple's proprietary tools and operating system, it made it too
difficult to ensure that Slither could work on Tiger and older.
- Fixed: Better code optimizations and other
miscellaneous bug fixes.
- Added: Inlet detection and other user configurable
artificial intelligence settings.
- Removed: CPU throttle since it was problematic.
- Updated: Built against wxMac 2.8.7 and latest OpenCV
CVS.
- Added: OS X and Ubuntu packages are built with
debugging symbols, hence the size. This will hopefully help bug fixes.
- Added: OS X packages are signed now.
- Many user interface fixes, especially for smaller
screens.

Released Ubuntu i386
package and OS X (universal) for

Saving analysis results to clipboard is temporarily disabled under OS X
builds due to what appears to be a bug in wxMac 2.8.6 raising a SIGSEGV.

Mac OS X: This
is an Apple OS X application bundle. Just uncompress it and place the
bundle wherever happens to be convenient for you. You can use it
regardless of whether you are running a PowerPC or Intel based Mac,
since it is a universal binary. OpenCV and wxWidgets runtimes are
statically linked, hence the size. Keep in mind that this is still
an alpha. Use at your own risk.

Win32: This
is a Nullsoft Installer for the Windows version. It has been tested
under Windows XP SP2, but should run under most Win32 systems.

Source:
Build instructions are included with the source. Compiling Slither from
source can be either simple or extremely difficult - depending on how
familiar you are with general unix development tools. You will need to
be familiar with SCons, Python, wxWidgets, OpenCV, C++, and the GNU
Autotools. You should also be comfortable with the command line.
