I am sorry to say that MEG is still unavailable. 4D are working on the problem and believe that they have determined the cause. We expect an engineer to visit this week and ti make adjustments to the main power supplies to the system. As soon as MEG is available I will let you know. MRI is working fine Gary -- Gary Green York Neuroimaging Centre The Biocentre York Science Park Innovation Way Heslington York YO10 5DG http://www.ynic.york.ac.uk tel. 01904 435349 fax 01904 435356 mobile 07986 778954
