Error: COMETS_HOME environmental variable is not set

[2132030]

I am using Linux and MATLAB_R2021b. I'm trying to run the comets simulation with this code:

runComets(layout,cometsDirectory)
I got this Error:
Error using runCometsOnDirectory
COMETS_HOME environmental variable is not set

' %% Add COMETS Java Classpath to MATLAB
cometshome = getenv('COMETS_HOME');
if isempty(cometshome)
error('COMETS_HOME environmental variable is not set')
end
gurobihome = getenv('GUROBI_HOME');
if isempty(gurobihome)
error('GUROBI_HOME environmental variable is not set')
end
javaclasspath(cometshome); % add COMETS classpath to MATLAB
javaclasspath(gurobihome); '

You need these system variables set properly. What system are you using? Windows, Linux?

Linux

You need to include these lines in your .bashrc file (or equivalent for other shells):

export COMETS_HOME=/projectnb/cometsfba/comets_2.11.1
export PATH=$PATH:$COMETS_HOME
export GUROBI_HOME=/share/pkg.7/gurobi/9.0.0/install/
export GUROBI_COMETS_HOME=/share/pkg.7/gurobi/9.0.0/install/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GUROBI_COMETS_HOME/lib/

export GUROBI_PATH=$GUROBI_HOME
export PATH=$PATH:$GUROBI_HOME/bin

Of course, you need to edit it to your system, the first line is setting the variable that is missing in your case. Set it to wherever you installed Comets. Let me know how it goes.
