This repository contains a couple of scripts that can be used to install publicly available LIGO software and connect to Gravitational Wave Open Science Center data sources via CVMFS.
They should work on a fresh SL7 install with SELinux set to permissive or disabled.
Just run them as root. Like any scripts that you download, you should at least give them a look to make sure that they are not doing something malicious.
After running these two scripts:
./cvmfs_sl7.sh
./lcsoft_rpms.sh
your SL7 box should be ready to run LIGO Software on publicly available LIGO data.
