Dear colleagues, We will have a seminar on next wednesday, 12th March about medical image analysis by Dr. Lee Harrison, UCL. We would like to invite you and your group members to join the seminar. The detail of the seminar is as follows. Please could you circulate this email to your group members, and we welcome every one to join the seminar. Best regards, Fan Zhang Computer Vision and Pattern Recognition Group, Computer Science Department, University of York, UK ----------------------------------------------------------------------------------------------------------------------------- Lee Harrison (University College London) Title: "Spatial models of functional magnetic resonance images" 11:15AM - 12:30AM, 12th March, Wednesday in Room CS103, Computer Science Building ----------------------------------------------------------------------------------------------------------------------------- "I will talk about Bayesian spatial models of fMRI time-series data. In particular, we use a weighted graph Laplacian (WGL) to partition a brain volume into computationally manageable segments, using an isoperimetric partitioning algorithm (Grady 2006). Data from each segment is then entered into a 2-level general linear model (GLM) with matrix-variate normal densities over likelihood and prior at the 1st and 2nd levels. The spatial covariance matrix of the prior over voxels is given by the heat kernel of a WGL and all parameters and hyperparameters e.g. controlling dispersion of the heat kernel, are optimized using an EM algorithm with Fisher-Scoring ascent scheme. The benefits of this approach are that GLM parameters have an explicit and (generally) non-stationary spatial model. This allows formal model comparison of different hypotheses about how data are generated, e.g. from a stationary or non-stationary spatial process." -- 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

YNiC today
by Gary Green 06 Mar '08

06 Mar '08

Dear colleagues Last week we held a YNiC Thursday seminar on using Unix on the Macs. The attendance was quite low suggesting that Users probably had enough knowledge on this topic for them to be able to do what they needed at that level of computing. The original idea was that the session would continue this week but as we have had apologies even from those who had attended last week, it seems that we should not hold today's seminar. So, NO seminar today. Next week there will be a new project presentation, 4pm, Thursday the 13th, YNiC open plan. All welcome 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

URGENT : Scratch space
by Gary Green 05 Mar '08

05 Mar '08

Dear colleagues As you know we have been encouraging users to use their 'scratch' disc space for temporary files and as a workspace for intermediate analysis. We monitor the total usage of this space daily and it is growing very rapidly. We predict that this space will run out in a few days if we do not act. The majority of the usage is by just a few users but, please, if you have a large amount of data/information in scratch, can you look at it and endeavour to delete anything that is redundant. If we do not do this then the systems will fail. One way of getting around these problems is to use a group space for your project. Group scratch is not used much and is an efficient way of sharing information without it having to be duplicated by each user, within a group, in their own scratch space. If your project does not have a group scratch directory then please email it-support(a)ynic.york.ac.uk thanks 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

MEG now available
by Gary Green 05 Mar '08

05 Mar '08

Dear Colleagues MEG is now up and running again. You can now book your MEG sessions again through Claire. It looks as though the Polhemus failed due to a fault in an serial line isolator. So the whole system failed due to a £5 component. Sorry! While we were waiting for a delivery of a new Polhemus system and the engineeer, the YNiC team took the opportunity to reorganise the MEG equipment room. The equipment and cables have been tidied, labelled and organised. Please do not change anything in the equipment room as there is now actually no need to change cables or equipment. The camera has also been moved in the MSR (magnetically shielded room) and it is now possible to monitor your subjects during an experiment even if you are using the large screen. Please remember to tell your subjects that they are being monitored.

Today at YNiC
by Gary Green 04 Mar '08

04 Mar '08

Dear colleagues Today we are being visited by the VC, the pro-VC for research and Sir David Cooksey. David Cooksey wrote the recent government report on medical research which has resulted in the setting up of the National Institute of Medical Research and the integration of the NHS R&D programme with the MRC. His current main interests are concerned with translational research. If ...., you were thinking of visiting YNiC yourself today then it would help us if you happened to be present in open plan between 1.30 and 2.15 with some interesting images on the screen. If anyone is doing experiments within MRI or MEG then please be prepared to have visitors ask some questions about what you are doing. Of course I cannot predict if they will visit, whether they will be on time or whether they will actually stop as we walk through open plan. thank you Gary -- Gary Green York Neuroimaging Centre The Biocentre York Science Park York YO10 5DG tel (+44) (0) 1904 435349 fax (+44) (0) 1904 435356 mobile 07986778954

Thursday Seminar
by Sam Johnson 27 Feb '08

27 Feb '08

Hello all, Just a reminder and a little more information about this Thursday's Seminar at YNiC. Mark has prepared an introduction to Unix that I will do my very best to translate into something we mere mortals can understand. This week we'll be covering some of the generic basics, including the permissions problem I know has been an issue of late. There'll also be information on some simple command line tools and the basics of scripting. Next week we'll be looking at YNiC specific information, including some useful hints and tips that will hopefully help to save you time and blood pressure. Thanks, Sam

MEG at YNiC : current status
by Gary Green 26 Feb '08

26 Feb '08

Dear colleagues I am sorry to have to announce that MEG is not working. We have had a problem since late last week with the Polhemus system which is needed for co-registration of the data with MRI. We thought we had fixed it over the weekend but it is now clear that we have to have a new unit flown in from San Diego. We will also need to get 4D engineers to attend to fix the problem as it is not simply one of replacing the unit. Unfortunately this means that MEG may be unavailable until the middle of next week. I know this is going to be a major inconvenience as MEG is currently very busy. As soon as it is working again we will let you know and will help you rebook or reorganise your time in MEG. We will almost certainly have to organise block booking so that several participants can be scanned one after the other to get through the backlog. The MEG system itself is working fine! Projects are stalled because of a piece of equipment that costs less than 1% of the original MEG cost.

YNiC ASC session on Virtual Electrode Analyses in MEG
by Andy Ellis 15 Feb '08

15 Feb '08

Dear All NOTES ON THE YNIC ANALYSIS SUPPORT COLLOQUIUM ON VIRTUAL ELECTRODE ANALYSES IN MEG, WEDNESDAY 13 FEBRUARY 2008. The current YNiC MEG tools allow us to create beautiful and defensible images showing how the brain's responses to stimuli evolve over time. But beamforming requires the comparison of active windows with passive windows, and the use of active windows less that 200 ms long is not recommended. So while moving windows convey a good initial impression of the progression of neural events, they do not take full advantage of MEG's potential for looking at the detailed timing of those events. There is another issue with beamformed brain maps, which is that it is not easy to compare results across conditions. You can point out that there is a significant response in a particular brain region in one condition of an experiment but not in another, but it could be that the response just makes it over the threshold in one condition and just falls below threshold in the other. The absolute difference in the magnitude of the two responses (or, to be accurate, the magnitude of the difference between the two active and passive conditions) may be small. Virtual electrodes offer the potential for asking intelligent questions about the strength and time course of events at specific points in the brain, allowing direct comparisons between conditions and making better use of the temporal resolution of MEG. Piers Cornelissen presented the results of some virtual electrode analyses he and his colleagues have done, comparing responses to different types of stimuli at different regions of interest in the brain. Piers showed results in the form of time-frequency histograms ('Stockwell plots'), separating out evoked and induced components of the total response; also event-related frequency (ERF) plots showing changes in the amplitude of evoked responses over time. He also discussed techniques that he and his colleagues have used for making statistical comparisons across conditions in both types of analysis. A lengthy and gripping discussion ranged over: 1. The best method to identify regions of interest, 2. How best, having identified a point of interest in a standardised brain, to identify the corresponding points in individual participant brains, and 3. What issues are involved in doing individual and group level analyses, and what would be the best analyses to adopt within YNiC, at least as interim solutions that will allow research groups to make progress with these techniques. Doing virtual electrode analyses at a group level is a complex business but has strong appeal to a number of researchers. Piers has a working solution which he and Uzma will document and make available. In complement to this documentation, YNiC will document the assumptions and issues associated with Virtual Electrode Analysis at the group level. It was also clear in the discussion that connectivity measures applied to Virtual Electrode analysis are going to be important to understanding more about the signals recorded in MEG, and more about how functional interactions involving different regions in the brain evolve over time. Deep thought will be given to this topic within YNiC. Ideas for future fora are welcomed.

Last nights YNiC ASC session.
by Michael Simpson 14 Feb '08

14 Feb '08

Dear all, just to say thanks to Andy and Piers for chairing last nights YNiC ASC session; a digest of which will be forwarded to the User list in due course. Given that we gave everyone the option to leave at 5pm, but everyone stayed until 5.30, I'll interpret it to have been and success! It was good that it generated so much discussion. On which note, would anyone like to volunteer to chair the next YNiC ASC session? If so, send an email to the ynic-users stating the topic for discussion, and the date on which you would like to hold the session. I look forward to hearing from you all ... thanks, Michael -- Dr Michael Simpson Science Liaison Officer York Neuroimaging Centre Innovation Way York YO10 5DG Tel: 01904 567614 Web: http://www.ynic.york.ac.uk
