Will sent me some info on how to install PUEOsim. I attached a markdown file he sent for how to install PUEOsim. He also sent the path to pre-compiled installation of PUEOsim. Here's the path to the pre-compiled installation: /users/PAS0654/wluszczak/PUEO_shared

Here is his full message, which details that you must also run set_env.sh before running PUEOsim:

a pre-compiled version is located at /users/PAS0654/wluszczak/PUEO_shared . Inside that directory, there's a set_env.sh script that you will need to source before running anything (hopefully this works, though there's a high probability you might run into permissions issues with the dependencies).

To run PUEOsim, use the following (see here for instructions: https://github.com/PUEOCollaboration/pueoSim):

./simulatePueo -i {inputFile} -o {outputDirectory} -r {runNumber} -n {numberOfNeutrinos} -e {energyExponent}

The outputs will be root files, but it should be possible (either modifying our own version directly or with a script) to print out the effective volume to a .txt to read.
