Dear Users I am sorry to have to tell you that MEG is down. We have an intermittent fault that causes the system to fail such that either the coil information cannot be captured and/or the channels all flat line. We have worked with 4D all week to try and isolate the cause of the fault but it appears that whatever it is creates a variety of different fault conditions depending on where in the process stream one has reached. It is likely that it is due to a processor board problem in the DAS rack. 4D will be arriving early next week to rectify the matter and will be replacing a number of cards in the main acquisition rack (the DAS). I am very sorry for the serious disruption this is causing some of you at such a critical time in your research studies. As soon as MEG is available again I will email you.
