MEG Analysis Code Changes
by Mark Hymers 13 Jun '11

13 Jun '11

Hi, We have just pushed some core changes to the YNiC NAF Beamforming code. The change is that nafEpochRejection will no longer produce what have become known as "Epoch Rejection Files" but will instead produce "Slice Rejection Files". "Epoch Rejection File" are simply a list of epochs of data which should be rejected during analysis due to artifacts. This can be problematic, as if you change your pre-trigger or epoch duration, the timings of the epochs will move around and you will reject data you didn't mean to, whilst not rejecting the data around your artifacts. The replacement for these are "Slice Rejection Files". These are a list of slice ranges containing bad data - simply a list of comma separated slice ranges; one per line. The analysis (beamformer) code itself will continue to accept Epoch Rejection Files which are listed in YAML files for analysis, but will produce "Deprecation Warnings" to remind you that you should consider converting. If you wish to convert an existing Epoch Rejection File to a Slice Rejection File, you can do one of the following: * Use the nafEpochRejectToSliceReject tool (documented at /mnt/common/naf/naf-doc/userref/scripts/nafEpochRejectToSliceReject.html ) * Load the Epoch Rejection file into nafEpochRejection using the -e flag and it will output a slice rejection file. * Load you study into the Study Definer Tool (nafStudyDefiner) and it will offer to convert all epoch rejection files into slice rejection files and update the YAML file for you at the same time. Although the nafEpochRejection and nafStudyDefiner tool will still read Epoch Rejection Files (to perform conversions), they will no longer allow you to edit or output them; they will only work with and output slice rejection files. It should be noted that internally, all of the code now converts Epoch Rejection Files to Slice Rejection Files. This means that strictly speaking, if you have overlapping epochs, a single epoch number in an epoch rejection may now result in more than one epoch being rejected. This should be a rare corner case and if you want to fully understand and see what is going on, you can use the nafShowEpochs tool to list the epochs you have and, if a epoch or slice rejection file is present in your YAML file, whether or not they will be rejected. This is one of the final big changes before we make the NAF tools available by default on the system. More on that soon. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

YNiC Downtime
by Mark Hymers 09 Jun '11

09 Jun '11

Dear all, We need to reboot the main fileservers at YNiC over the weekend, most likely on Saturday. Can I therefore ask that people log off at the end of Friday and do not leave jobs running on the cluster which will continue beyond Saturday morning - any jobs running at that point will be cancelled. This does not affect the Psychology email server. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

FYI ------------------------------- Dear colleagues, please find below two separate announcements for open positions in our research team. Kind regards, Alfons Schnitzler & Katja Biermann-Ruben /**********************************************************************/ PhD Position in Düsseldorf A *PhD position* is available at the Institute of Clinical Neuroscience and Medical Psychology, Heinrich-Heine-University Düsseldorf, to study neural representations of action related concepts. The successful candidate will be expected to work within the interdisciplinary collaborative research center (CRC/SFB 991) "The Structures of Representation in Language, Science and Cognition" starting July 2011. Within this linguistic CRC and on the theoretical basis of embodiment and the mirror neuron system our neuroscientific project investigates the functional relevance of the motor cortex for conceptual representation of verbs and nouns which derived from action verbs. Methods will be non-invasive 306-channel MEG, TMS and behavioural priming. Successful candidates will have a MSc in psychology, neuroscience or related fields and are highly motivated to learn MEG and TMS measurement and data analysis. Preference will be given to candidates with experimental practice. We offer a stimulating and inspiring atmosphere in a young, interdisciplinary team of neurologists, psychologists, physicists, and biologists.

At risk period tomorrow lunchtime
by Mark Hymers 01 Jun '11

01 Jun '11

Hi, The UPS in the YNiC server room will be undergoing its yearly maintanence tomorrow from around 11:30. This should have no effect on users unless we suffer from a power cut at exactly the same time as the UPS is being maintained (a highly unlikely scenario). In this case, there will be a short outage whilst we bring the servers back up again. Thanks, and sorry for the short notice. Mark -- Mark Hymers York Neuroimaging Centre
