Installation of TM4 MIDAS 2.21

Java, already installed.

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.

% 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

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

% sudo chown -R root:root /opt/bio/sources/MIDAS_V2.21
% sudo chmod 755 /opt/bio/sources/MIDAS_V2.21

• 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:

#!/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

• This script needs to be made available to all:

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

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

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

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