Hi André Graça, This is not an answer to your exact question (I do not know the status of the server), but my suggestion would be to instead try using the "fitmap" command for a local calculation. This command can do sequential fitting of multiple structures, or symmetrical fitting of multimers, among other options. The sequential and symmetric options are only in the command, not the tool dialog. The command is described here: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html> In this way, you may be able to accomplish what you want with more expediency. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi, I am using Multifit for the first time and wondering if a few hours are not long enough to wait for a server response. The task panel shows from the beginning the status as ‘waiting for response from Opal server’. I read on the paper (2011) about Multifit that “The typical running time is about 20 min for assemblies with tens of thousands of atoms", which is the case. I wonder if it is not running yet and it is queued in the server, or if it takes a long time depending on anything that I might have set up wrongly. Could anyone help me to figure this out? Thank you, André Graça
