Our web server maraca.d.umn.edu was updated over the weekend, and in the process a few bad things happened (like the umls database seemed to be removed). I'll need to set up the web interface and as a part of that reinstall the UMLS, so I'm afraid maraca will not be available until at least Mon Jan 22. The good news is I will reinstall using the most current version of the UMLS, and we've been overdue for that upgrade for some time.
My apologies for the inconvenience, and stay tuned here for updates. Thank you, Ted
