I would suggest downloading the Linux version and unpack it in an emc directory in your home:
cd ~
mkdir emc
cd emc
tar xf /your/download/folder/emc_linux_fc31_v9.4.4_20220801.tgz
This unpacks EMC in ~/emc/v9.4.4. The next step is to make some changes to your ~/.bashrc by adding the environment variable EMC_ROOT and adding EMC’s executable and scripts to your path. Use your favorite text editor open ~/.bashrc (mine is vi) and add the following at the end:
export EMC_ROOT=$HOME/emc/v9.4.4
export PATH=$PATH:$EMC_ROOT/bin:$EMC_ROOT/scripts
After saving, you can source your ~/.bash as follows to activate your changes:
. ~/.bashrc
Additionally, you could add the EMC GUI package to your ~/.vmdrc. Add the following line at the end:
source $::env(EMC_ROOT)/vmd/packages.tcl
The latter only works, if you have defined EMC_ROOT in your ~/.bashrc. To use the EMC GUI, you will have to install VMD, as the GUI is a plugin to VMD. Once installed, the GUI can be found at the Extensions pull-down in the VMD main menu.
