A new version of Amber is released every two years. To check if you are using the correct version for your project, refer to this table. You can check which version of Amber you are using by typing:

   echo $AMBERHOME

If $AMBERHOME is not set, or you wish to change the version, edit your bashrc profile using emacs:

   emacs ~/.bashrc

Insert the following after "# User specific aliases and functions"

Amber18

   export AMBERHOME=/home/apps/CENTOS7/amber/amber18
   export PATH=$AMBERHOME/bin:/bin:$PATH

Amber20

   export AMBERHOME=/share/apps/CENTOS8/ohpc/software/amber/20
   export PATH=$AMBERHOME/bin:/bin:$PATH

Amber22

   export AMBERHOME=/share/apps/CENTOS7/amber/amber22
   export PATH=$AMBERHOME/bin:/bin:$PATH
