====== Installation of TM4 MIDAS 2.21 ======

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

Java, already installed.

===== Procedure =====

Here is the procedure to install MIDAS:

  * MIDAS is distributed as a JAR archive (Midas.jar) and a collection of auxiliary JAR files. Download and decompress the ZIP archive in ''/home/bioubuntu'', create a ''libs'' folder in it and move this folder into ''/opt/bio/sources''.

<code bash>
% mkdir /home/bioubuntu/MIDAS_V2.21/libs
% mv /home/bioubuntu/MIDAS_V2.21/*.jar /home/bioubuntu/MIDAS_V2.21/libs
% sudo mv /home/bioubuntu/MIDAS_V2.21 /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/MIDAS_V2.21
% sudo chmod 755 /opt/bio/sources/MIDAS_V2.21
</code>

  * Once you are in ''/opt/bio/sources/MIDAS_V2.21'', you need to edit the ''midas.sh'' script to make it more applicable. Open it and remove its content to put the following lines instead:

<code bash>
#!/bin/sh
TM4MIDAS_HOME=/opt/bio/sources/MIDAS_V2.21

for jar in $TM4MIDAS_HOME/lib/*.jar
do
  if [ -z "$CLASSPATH" ]
  then
    CLASSPATH=$jar
  else
    CLASSPATH=$jar:$CLASSPATH
  fi
done

export CLASSPATH

java -Xmx768m -Xms256m -cp $CLASSPATH:. org.tigr.midas.display.Midas
</code>

  * This script needs to be made available to all:

<code bash>
% sudo chmod ugo+x midas.sh
% sudo ln -s /opt/bio/sources/MIDAS_V2.21/midas.sh /usr/local/bin/midas
</code>

  * To add MIDAS to the Impilo application menu, you have to edit the Xfce4 application menu:

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

  * The three items to add are :
    * Item: Launcher
    * Name: TM4 MIDAS
    * Command: midas
