26 Jan '12

Hello, I would like to try out the Tools-->surface-->write dipoles function, but I don't know how to read the file that it outputs. Do I need to use a special file extension when I name the file? Thank you, Amy

22-30 June 2012: 10th IEEE EMBS International Summer School on Biomedical Imaging (fwd)
by Lilla Zollei 26 Jan '12

26 Jan '12

Hi, Could you forward the below to interested students / collaborators? I attended this summer school both as a student and as a lecturer in the past and I can highly reccomend it. --Lilla ------------------------------------------------------------------------ CALL FOR PARTICIPATION (APOLOGIES FOR MULTIPLE COPIES) 10th IEEE EMBS International Summer School on Biomedical Imaging 22-30 June 2012 Berder Island, France WEB http://ieeess.enst-bretagne.fr Application deadline : Feb. 15, 2012 E-mail : Valerie.Burdin(a)telecom-bretagne.eu Chair : Christian ROUX Co-chair : Jean-Louis COATRIEUX The spirit of this Summer School is inspired by the most prestigious school ever founded in France, Saint Flour, the influence of which has spread to generations of researchers in Mathematics. Since its establishment in Brittany in 1994, this school has become a worldwide reference. It is resolutely international (participants from more than twenty countries have participated to the previous editions) and accessible to young scientists. It is an open yet privileged place for exchanges and discussions of major on-going work. Informal and warm, at a location where the sea and the land combine in a time varying relation, this school brings together, every two years for ten days, the world great teachers and researchers in Biomedical Imaging. Lectures, seminars, and discussions are organized at the highest level, but with the freedom of spirit that is the tradition of Brittany. The school objective is to contribute without any exclusion to advances in a rapidly evolving field, and to foster participation in the adventure of research. It provides up-to-date, state-of-art knowledge on emerging areas and addresses important issues dealing with complex, multivariate systems, going from basic to applied research. Audience: The Summer School is open to graduate students (M.S., PhD), post doctoral scientists, radiologists, biologists, researchers and engineers in industry. 2012 Program SIMON CHERRY, University of California Davis, USA, “Molecular Imaging” RUSS TAYLOR, Johns Hopkins University, USA “Computer-Integrated Surgery” MICHAEL UNSER, Ecole Polytechnique Fédérale de Lausanne, Switzerland “Biomedical Image Analysis” SIMON ARRIDGE, University College London, UK “Optical Tomography” KOJI IKUTA, University of Tokyo, Japan “Nano Robots for Cell Investigation” JEAN YVES CHAPELON, INSERM, Lyon, France,“Therapeutic Ultrasound” Junior Lecturer It is now an established tradition to invite the participants of the previous schools (2004, 2006, 2008and 2010) to serve as Junior Lecturer for the next one (2012). An international Committee will select the junior lecturer. The topics that can be addressed by this Junior Lecture are very open, as far as they concern Biomedical Imaging. The talk to be given is expected to complement the lectures already displayed. Experience and originality of the subject, interest for the audience are the basic criteria to fulfill. Travelling expenses lodging and fees will be paid. http://ieeess.enst-bretagne.fr/index.php?pid=8 Call for Participation The number of attendees (traditionally coming from more than 30 countries all over the world) is strictly limited (45) and applications must be submitted as early as possible (the formal deadline being February 15, 2012). An international committee will select the candidates by March 15. Participants are encouraged to present their research work through Posters. http://ieeess.enst-bretagne.fr/index.php?pid=3 Candidature submission is open from Nov. 15, 2011 to Feb. 15, 2012 For information contact : Valérie Burdin, Département ITI, TELECOM Bretagne, CS 83818, 29238 Brest Cedex 3, France E-mail : Valerie.Burdin(a)telecom-bretagne.eu

hippocampal subfields segmentation
by JOANA BRAGA PEREIRA 26 Jan '12

26 Jan '12

Dear Koen & Freesurfers, I've been working with the GEMS tool for hippocampal subfields segmentation and have a question I would like to ask you all. I've noticed that the CA1 sector appears to be quite small compared to other subfields (CA2-3 seems to be the largest), while previous studies suggest that it should be the largest subfield of the hippocampus. Why? On the other hand, I have read the paper by Van Leemput et al. [2009] and how the subfields were initially delineated and was wondering what atlas was the manual tracing based on? Many thanks! joana

overlay alignment in tkmedit
by Anthony Dick 26 Jan '12

26 Jan '12

Hello, I am trying to train a cerebellar atlas based on 20 manually parcellated cerebellums. I have run the anatomical through freesurfer. When I try to load the overlay (parcellation) in tkmedit, the underlay (e.g., orig.mgz, T1.mgz) and the overlay (the parcellation) are no longer in alignment. However, loaded in AFNI the underlay and overlay of course align. Is there a quick fix to get them in alignment?

Qdec Design
by dolphinede＠aol.com 26 Jan '12

26 Jan '12

Dear freesurfer experts, i am really a newbie in freesurfer. I want to compare the thickness between different ages. Is it correct to use gender as fixed factor, to look for its influence on thickness ? If i find no effects of gender on thickness i can put the factor gender out of the model ? Otherwise if there will be effects of gender on thickness it remains in the model. So that the effect of age on thickness can be questioned like this: Does the correlation between thickness and age, accounting for gender, differ from zero? Best regards Daniel

Re: [Freesurfer] cwp threshold
by Douglas N Greve 26 Jan '12

26 Jan '12

The FA values are used to compute a p-value at each voxel. The p-value map is thresholded using the threshold you supply (3 in this case). Clusters are formed based on the number neighboring/contiguous voxels above threshold. The p-value for the cluster is determined based on the number of voxels in the cluster, the threshold you used, the amount of smoothing, and the number of voxels in the brain mask (ie, the search space). doug Antonella Kis wrote: > I understand that but how this value is related to my FA values?

qdec: vertex thickness values
by Cat Chong 26 Jan '12

26 Jan '12

Dear Freesurfers: I am comparing two groups in qdec. I am looking at the scatter plot function for a specific vertex for thickness to age correlation. If I "click" on a dot on the scatter plot, it will provide me the thickness values for that vertex for a specific person in the scatter plot function as well as in the terminal. Is there a way to get ALL the thickness values (for that vertex) for everybody at once, rather than selecting each one by hand in the scatter plot function? thank you very much for your help, cheers, cat
