Hello all, I'm pleased to report that MEG has been stable since Thursday evening. We ran several tests on Friday and the system is working well and the replacement board seems to have solved the problem. Those with active MEG projects should be able to scan with much greater confidence from now on. I'm afraid the news isn't quite so good from MRI, the distortions in the images are still present. Engineers are on site and working on the problem, and we'll let you know as and when progress is made. Thanks, Sam -- Sam Johnson Science Manager, York NeuroImaging Centre University of York http://www.ynic.york.ac.uk
