====== Installation of TM4 MeV 4.5.1 ======

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

Java, already installed.

===== Procedure =====

Here is the procedure to install MeV:

  * MeV is distributed as a startup script that encapsulated a collection of JAR files with the application and auxiliaries. In Linux, MeV is distributed wither in a 32-bit or 64-bit version since a local R install is installed (as of version 4.5, there is an internal dependency between MeV and R which makes MeV dependant on a specific verion of R); download the right version for your system! Decompress the ZIP archive under ''/home/bioubuntu'' and move this folder to ''/opt/bio/sources''.

<code bash>
% sudo mv /home/bioubuntu/MeV_4_5_1 /opt/bio/sources
</code>

  * This folder should belong to ''root'' and its permissions should be set to ''755''.

<code bash>
% sudo chown -R root:root /opt/bio/sources/MeV_4_5_1
% sudo chmod 755 /opt/bio/sources/MeV_4_5_1
</code>

  * Once you are in ''/opt/bio/sources/MeV_4_5_1'', you have to edit the ''tmev.sh'' script so that it will work in an Impilo install. Open it and edit the following lines:

<code bash>
#blablabla...
for jar in lib/*.jar
</code>

now becomes

<code bash>
#blablabla...
TM4MEV_HOME=/opt/bio/sources/MeV_4_5_1

for jar in $TM4MEV_HOME/lib/*.jar
</code>

and 

<code bash>
#blablabla...
CurrDIR=`pwd`
</code>

decomes

<code bash>
#blablabla...
CurrDIR=$TM4MEV_HOME
</code>

  * You need to make this script available to all (it is already executable):

<code bash>
% sudo ln -s /opt/bio/sources/MeV_4_5_1/tmev.sh /usr/local/bin/tmev
</code>

  * To add MeV to the Impilo application menu, you need to edit the Xfce4 configuration file:

<code bash>
% sudo xfce4-menueditor /etc/xdg/xfce4/desktop/menu.xml
</code>

  * The three things to add are :
    * Item: Launcher
    * Name: TM4 MeV
    * Command: tmev
