Using segmentation for wm/pial edits
by Lena Palaniyappan 14 Dec '09

14 Dec '09

Though the pial surface and wm surface follow expected course, there are some regions that are misclassified when the colortable is overlaid. Please see the example below... Should I worry?

Co-registration in FS
by Xinian Zuo 14 Dec '09

14 Dec '09

Hi FSers, I am new to freesurfer. now start to use it for looking at struc-func relationship. Normally, in fsl, I employ bet for both example_func and highresh anat. it means that the func_brain and anat_brain are fed into flirt to estimate the co-registration. here, i try to use reg_feat2anat to do this. but in this new version (4.5), it told me the betfunc command can not be found. thus I just used the version without --bet. the results in tksurfer looked not good. I am guessing it was caused by the highres with large neck areas. MY QUESTION is how can I trigger reg_feat2anat (or whatever other commands) to take skull-stripped highres for the co-registration (in fact, the brainmask.mgz already there)? Or I was wrong, reg_feat2anat did this consideration? Any suggestions would be appreciated! -- Xinian Zuo, Ph.D Associate Research Scientist Institute for Pediatric Neuroscience NYU Child Study Center 215 Lexington Ave., 14th Floor New York, NY 10016 Phone: 212-263-4735 Public: www.AboutOurKids.org Academic: http://publicationslist.org/xinian.zuo Personal: zuoxinian.googlepages.com Blog: http://restbrain.blogspot.com

Wm/pial edits misclassification
by Lena Palaniyappan 12 Dec '09

12 Dec '09

Hi all Please see the attached images slices 108 to 111 What is happening at precentral / middle frontal white matter? How should I be correcting this? The wm slices as you can see have missing volumes. I cannot fill these spaces in wm surface as there is no obvious white matter in the original surface. How should I go about correcting this?

postdoc position in Leiden, The Netherlands: studies on resting-state and activation EEG-fMRI during sleep and wakefulness in healthy subjects and patient with sleep disorders including insomnia and narcolepsy
by Diederick Stoffers 12 Dec '09

12 Dec '09

LEIDEN UNIVERSITY MEDICAL CENTER The Leiden University Medical Center (LUMC) has initiated the interdisciplinary Sleep Neuroscience Center Leiden. Its focus is fundamental and strategic scientific and clinical research on sleep Within the Departments of Neurology and Neuroradiology, and in close collaboration with Dr. E.J.W. van Someren’s Sleep & Cognition group at the Netherlands Institute for Neuroscience, a position is available for a Postdoc (m/f) 38 hours per week Project information: This project is funded by a LUMC starting grant for the Sleep Neuroscience Center Leiden. It has become evident over the last decade that sleep is an essential component of normal cognitive functioning and maintenance of brain structure and function at the cellular to the systems level. In addition, disturbed sleep crucially contributes to major health problems associated with metabolic regulation, aging and psychiatry. The present project aims to elucidate the association between activatiion of the default mode resting state network, it’s structural backbone, and travelling slow oscillations during sleep. A second focus is on the involvement of the default mode network in deviant switching between sleep and wakefulness in narcolepsy and insomnia. Philips 7T and 3T scanners are available for structural and functional MRI. The aim is to do EEG-MRI with the new Electrical Geodesics Inc (EGI) system. The project will be performed in close collaboration with Dr. S. Rombouts (director of the Leiden Institute for Brain and Cognition: LIBC) and with the Sleep & Cognition group at the Netherlands Institute for Neuroscience. A 0.5 FTE lab technician will support the project. Requirements: A strong scientific track record including publications is essential for the Postdoc. The Postdoc will be responsible for studies on resting-state and activation EEG-fMRI during sleep and wakefulness in healthy subjects and patient with sleep disorders including insomnia and narcolepsy. Appoinment: This position involves a temporary appointment for three years. Salary: Depending on training and work experience according to the collective Agreement for Dutch Universities (CAO-Nederlandse Universiteiten), including 8% holiday pay and a 8.3% year-end bonus. We offer an extensive package of fringe benefits. Work location: The Leiden University Medical Center, Leiden. Information: For further information about this position, you may contact Dr. EJW Van Someren (e-mail e.van.someren(a)nin.knaw.nl) or Dr. SARB Rombouts (s.a.r.b.rombouts(a)lumc.nl ). Information on the groups is found at http://www.nin.knaw.nl/research_groups/van_someren_group/ and at http://www.libc-leiden.nl Application: You may send your application letter, curriculum vitae and the names of 2 references to Dr. EJW Van Someren (Laboratory for Neurophysiology, Department of Molecular Cell Biology, LUMC S-05-P, PO Box 9600, 2300 RC Leiden, The Netherlands) or preferably by email: e.van.someren(a)nin.knaw.nl. Application deadline: January 14, 2010. Any acquisition further to this advertisement will not be appreciated

how to evaluate our own template without creating our own atlas
by Guang Zeng 11 Dec '09

11 Dec '09

Hi, there, We created our own template using 10 subjects, now we'd like to know how good it is compare to FS's default template. We do not create our own atlas yet which need manully label all the regions in the training set. Is there a way to do this kind of comparison? Is it possible to do some kind registration using ?h.white and ?h.sphere. reg, and load the registered ?h.white using tkmedit? Thanks a lot!

how to load lh.jacobian_white in tkmedit
by Guang Zeng 11 Dec '09

11 Dec '09

Hi, there, I'd like to load lh.jacobian_white using tkmedit to check how much the white surface was distorted in order to register to the spherical atlas my command line is tkmedit subj_id brainmask.mgz rh.white -aux T1.mgz -aux-surface lh.jacobian_white -segmentation aseg.mgz $FREESURFER_HOME/FreeSurferColorLUT.txt But I got an error, =================================== ERROR: A segfault has occurred. This is not your fault, : but is most likely an unrecoverable error and has : made the program unstable. : : Please send the contents of the file .xdebug_tkmedit : that should be in this directory to analysis-bugs(a)nmr.mgh.harvard.edu : : Now exiting... : Anyone can help? Thanks a lot! Guang _________________________________________________________________ Your E-mail and More On-the-Go. Get Windows Live Hotmail Free. http://clk.atdmt.com/GBL/go/171222985/direct/01/
