MEG status

20 Jul '07

Dear All, The 4-D engineer has repaired the dewar positioning system. We are hopeful that the system will be up and running as normal from Monday onwards. Some final checks and testing will be performed before then. Tony

DSO arrangements
by a.morland＠psychology.york.ac.uk 18 Jul '07

18 Jul '07

Dear All, As Gary mentioned at the end of a recent Thursday evening meeting, the DSO will now occupy a desk in the open plan area so that he/she is more accessible to users. The desk is in the corner of the room and will have the name of the DSO on the desk. If the DSO is not at the desk and is working elsewhere in the centre, details of where he/she can be found will be on the desk. Please note that the DSO can be approached 10am-12pm and 2pm-4pm. Tony

MRI and MEG
by a.morland＠psychology.york.ac.uk 17 Jul '07

17 Jul '07

Dear All, The MEG scanner has a problem with the dewar, as has been previously reported. Until further notice, no scanning. The radiographer is off sick this week and currently Andre is assisting with as much MRI scanning as he can. It will be necessary however to cancel or shorten some scanning sessions. Please do not book any more MRI sessions this week. Tony

IMPORTANT - VALIDATING BEAMFORMING OUTPUTS
by Andre Gouws 13 Jul '07

13 Jul '07

We have always stressed the importance of checking a few of the manual steps in the beamforming processing stream where possible. These include the outputs generated by the co-registration routines which co-register your MEG headshape to your structural MRI for each subject, and simultaneously calculate the local sphere sources for each channel in the MEG sensor array. This information, calculated early in the processing tree is obviously vital for all post-processing steps. You should be routinely checking that the co-registration itself is accurate and that the spheres generated make are 'sensible' for each sensor. If you are not doing this you are STRONGLY ENCOURAGED to do so. Whilst there have been very few instances of the outputs failing (only 2 in the last year!) they have had significant effects on results for both individuals and groups. These errors are easily resolved if detected. Please see the following page for more information: https://www.ynic.york.ac.uk/doc/BeamformerUsage and see "/STEP 3 - Visually check that the co-registration is reasonable for each subject and associated MEG run/" (Thanks to those who brought this to our attention!) -- ************************************************************************ Andre Gouws User Support Manager York Neuroimaging Centre The Biocentre York Science Park Heslington YO10 5DG Tel: +44 (0) 1904 435328 Fax: +44 (0) 1904 435356

Thursday Evening
by Sam Johnson 09 Jul '07

09 Jul '07

Hello all, Due to the rearranging of sessions there's a bit of a hole in the schedule and the next Thursday evening will be the 26th, when Piers will talk. Unless of course we have any volunteers, or (without making any promises) requests for more training biased sessions. Thanks, Sam

re: use of fridge, kitchen and toilets
by Gary Green 05 Jul '07

05 Jul '07

Dear users and staff Just a gentle reminder. Please, please do not use the fridge in ynic reception for food. I have just had to do archeology on someone's lunch. It is not very good for public relations when people try and get some milk but are faced with fungal blooms. Also, please can everyone use the kitchen in the link corridor between the biocentre and the innovation centre rather than the one near biocentre reception. This is because the reception kitchen is for the use of the biocentre team rather than tenants. The other kitchen does have a fridge for your lunches, etc. Last, and sorry to keep on, please can you use the toilets by the biocentre reception rather than the toilet in the mri corridor. The toilet in the mri corridor is really for patients and participants rather than users. The problem is that the mri toilet is not keeping up with demand! thanks Gary ps Good news. Work starts very soon on the new cafeteria at the Biocentre. Details are on the notice board in the Open Plan office. It should be available in the autumn. -- 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
