====== Installation of ImageJ 1.44d ======

===== Additional libraries ===== 

Java, already installed.

===== Procedure =====

here is the procedure to install ImageJ:

  * ImageJ is contained in a JAR archive, all ready to execute via a script called ''run'' found in the folder created after decompressing the Zip archive.
 
<code bash>
% wget http://rsbweb.nih.gov/ij/download/zips/ij143.zip
% unzip ij143.zip
% cd ImageJ && ./run&
</code>

  * ImageJ has always been a fast-evolving program... A consequence of this is that the archive you just downloaded is rarely the latest available version. The last command of the preciding block of commands will start ImageJ to allow you to update to the latest :-) In the menu, yo ushould be able to see a ** Help ** menu. In thuis menu, select //Update ImageJ...//. A window will pop up and you only have to click //Ok// to do the update to the latest version!

  * The whole ImageJ folder has to be moved to ''/opt/bio/sources''. This folder should belong to ''root'' and its permissions set to ''755''.

<code bash>
% sudo chown -R root:root /opt/bio/sources/ImageJ
% sudo chmod 755 /opt/bio/sources/ImageJ
</code>

  * Once you are in ''/opt/bio/sources/ImageJ'', you need to edit the ''run'' script so that it looks like this:
<code bash>
#!/bin/bash
export IJ_HOME=/opt/bio/sources/ImageJ
java -Xmx512m -jar $IJ_HOME/ij.jar
</code>

  * You need to make this script available to all:
<code bash>
% sudo ln -s /opt/bio/sources/ImageJ/run /usr/local/bin/runImageJ
</code>

  * To add ImageJ to the Impilo application menu, you need to edit the Xfce4 configuration file:
    * More to come...

  * To have access to ImageJ from the command line:

<code bash>
% runImageJ
