OPUS for Linux is free for your evaluation. Use it at your own risk. No support from Bruker Optics.
Please note that these package files are older, unfortunately (a replacement currently is not available yet). This means that they may be incompatible with (too) new Linux distributions, thus one may need to use older Linux distributions such as <= Ubuntu 12.04LTS (possibly via e.g. VirtualBox).
