FRAP manual updated

There is always some confusion when deriving Diffusion coefficient after Soumpasis fitting in FRAP, whether to use radius or diameter for the parameter “w”. As manual has been saying, this “w” is indeed radius, not diameter. I made a bit of stress on this part.

Dokuwiki Configuration: URL cleaning

In local.php (not accessible so configured through configuration manager)

   $conf['userewrite'] = '1';
   $conf['useslash'] = 1;

Copied .htaccess.dist to .htaccess, then in .htaccess, *une-**commented out lines shown in Red

14 ## Uncomment these rules if you want to have nice URLs using
15 ## $conf['userewrite'] = 1 - not needed for rewrite mode 2
16 RewriteEngine on
17 #
18 ## Not all installations will require the following line. If you do,
19 ## change “/dokuwiki” to the path to your dokuwiki directory relative
20 ## to your document root.
21 RewriteBase /

23 ## If you enable DokuWikis XML-RPC interface, you should consider to
24 ## restrict access to it over HTTPS only! Uncomment the following two

27 #RewriteRule ^lib/exe/xmlrpc.php$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]

FIJI/ImageJ Hackathon / March 15th-26th, 2010 @EMBL

for details, go to FIJI 2010 Page

Dear All,

We would like to draw your attention on the following initiative:

Fiji/ImageJ Hackathon
March 15th-26th, 2010
Room 6.51a

A group of around 15 core developers of FIJI/ImageJ will meet here at the EMBL with the aim of enhancing 3D visualization and timelapse analysis in ImageJ/Fiji.

What is Fiji?

Fiji (“Fiji is just ImageJ”) ( It emerged as a user-driven response to organize ImageJ's collection of plugins, along with comprehensive user documentation, and version-controlled code for developers. The developers introduced new ImageJ libraries for image registration, stitching, segmentation, feature extraction, 3D visualization, and numerous others.

What is an Hackathon?

It is a software development sprints. Hosting such an initiative here at the EMBL is a great opportunity for both EMBL imaging processing specialists and researchers to contribute to the open Fiji project, and have a saying in the development of this widely popular software.

Summary of the initiative


Please note that the Hachathon is an open platform however, if you want to participate please send and email to Kota Miura ( ).

Advanced Microscopy Workshop

EMBL Practical Course “Advanced Microscopy” will be held next week (March 8 - 12, 2010) in EMBL Heidelberg.

Kota will give a talk on Thursday about object tracking in cell and developmental biology, and also teach practicals during afternoon of the same day.
