Java, already installed.

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. The whole ImageJ folder has to be moved to /opt/bio/sources.

• This folder should belong to root and its permissions set to 755.

% sudo chown -R root:root /opt/bio/sources/ImageJ
% sudo chmod 755 /opt/bio/sources/ImageJ

• Once you are in /opt/bio/sources/ImageJ, you need to edit the run script so that it looks like this:

export IJ_HOME=/opt/bio/sources/ImageJ
java -Xmx512m -jar $IJ_HOME/ij.jar

• You need to make this script available to all:

% sudo ln -s /opt/bio/sources/ImageJ/run /usr/local/bin/runImageJ

• To add ImageJ to the Impilo application menu, you need to edit the Xfce4 configuration file:

% sudo xfce4-menueditor /etc/xdg/xfce4/desktop/menu.xml

• The three things to add are :
  • Item: Launcher
  • Name: ImageJ
  • Command: runImageJ
