Are there any other open sources IDS that not based on snort?

[Chatprechakul Mr N <N.Chatprechakul () rmcs cranfield ac uk>]

Hi all,
     I am doing a research on network security concentrating on correlation
of data from security products already in the network. I try to set up the
testbed network and run a few IDSes on this network. However, when I try to
find opensource IDS to run I would like different IDS to be difference
enough so that they provide diversity in the network. But from what I am
trying to find most of the opensource is based on snort (forgive me if I am
wrong).
     So my question is if anyone know other IDS either host based or network
based apart from snort? I have try some website that has list of IDS
research, most of them do not exist as a product anymore (if they are ever
exist).
