Installing and starting the OT on Linux

  1. Download the ALMA OT for Linux including JRE (x64).
  2. Open a terminal and extract the ALMA OT tarball
    	> tar xf alma-ot-c12-linux-jre-x64.tgz
    
  3. Change directory into the setup directory and execute the setup-unix.sh shell script
    	> cd alma-ot-c12/setup
    	> ./setup-unix.sh
    	> cd ..
    
  4. Launch the ALMA OT application from the command line
    	> ./alma-ot.sh
    

Please note: if you are planning to work on large proposals (e.g. including many sources and/or science goals) or on a Large Program you may consider increasing the maximum heap space memory size. This will improve the performance and usability of the ALMA OT application. The default value is typically 8 G but you can increase the maximum heap size by using the -max-heap-size command line option. In this example we increase the maximum heap space memory size to 16 G. You can set it to higher values, but please keep in mind the maximum memory available on your computer:

	> ./alma-ot.sh --max-heap-size 16
