Relion is installed from git. The ./build script should work for both stable (tags) and unstable (branches) versions. It should be run on Merlin6 from an admin account.

Currently only gcc is used. Better performance is reported with intel icc and MKL, but this would require additional openmpi variants.

After running ./build, install relion scripts from the repository at https://git.psi.ch/lsm-hpce/relion-scripts
