UPDATES on Brainhack 2013 (including stipend application extension)
by MCLAREN, Donald 01 Oct '13

01 Oct '13

Dear All, Brainhack 2013 will be taking place in just under a month outside of Paris, France. A welcome reception will be held on the evening of October 23rd to be followed by the hackathon on October 24th, 25th, and 26th. Brainhack 2013 will be highlighted by "Ignite" talks by: - *Yves Burnod, PhD,<http://www.imed.jussieu.fr/en/outils/affiche_personne.php?pers_id=217> INSERM (French national Institute for Health)* - *Jean Daunizeau, PhD,<https://sites.google.com/site/jeandaunizeauswebsite/>l’Institut du Cerveau et de la Moelle épinière* - *Martin Lindquist, PhD, <http://www.biostat.jhsph.edu/~mlindqui/> Department of Biostatistics of the Johns Hopkins University Bloomberg School of Public Health.* - *Ziad Saad, PhD,<http://intramural.nimh.nih.gov/research/clinicians/sc_saad_z.html> US National Institutes of Mental Health Statistical and Scientific Computing Core* - *Gaël Varoquaux, PhD, <http://gael-varoquaux.info/> INRIA at the Neurospin* - *Xinian Zuo, PhD, <http://lfcd.psych.ac.cn/> Institute of Psychology, Chinese Academy of Science* UPDATES: We have four important updates about Brainhack 2013: (1) Brainhack.org back online after being offline at the end of last week and over the weekend. Details about Brainhack 2013 can now be found there. (2) Due to the technical problems last week, we've extend the stipend application deadline to 11:59 PM EST on Thursday October 3rd. See brainhack.org for details on how to apply. (3) Attendees can now complete their registration by paying the registration fees at: http://dr01.azur-colloque.cnrs.fr Instructions on this process can be found here: http://www.brainhack.org/?page_id=5425. The deadline for registering is October 15th and payment must be received by October 16th. (4) If you want to have your poster abstract appear in the Brainhack 2013 Program, please submit your abstract online at brainhack.org. Posters will be presented electronically during the welcome reception. Hope to see you next Month. > Please let Donald McLaren know if you have any questions.

overlay mni152 activation -- difference between tksurfer and freeview
by Yang, Daniel 01 Oct '13

01 Oct '13

Dear FreeSurfer Experts, I am trying to visualize fMRI activation (generated from fsl) on the fsaverage inflated surface, using mni152.register.dat. It's odd that I find the results to be slightly different between tksurfer and freeview. However, I made sure that I am using the same threshold... Judging from fslview, I think the result with freeview is more accurate -- is it due to tksurfer loading orig.mgz by default, and free view loading something else? Thanks!

DODS slope information
by Jacobs H (NP) 01 Oct '13

01 Oct '13

Hi Freesurfers, I just looked at my cortical thickness results, in which I performed an interaction between group (2 groups) and cognition (continuous). I see regions popping up, which is great! Especially since they are related to the task. Now, I made a scatterplot of some of these vertices to get a better understanding of the effect. However, I am wondering how I can figure out if the slope within each group is significant. How can I examine that? Thanks!

Xhemi-Fsaverage Vs myatlas
by amirhossein manzouri 01 Oct '13

Dear FS experts, I want to perform asymmetry study in a group of subjects. I have created myatlas.i3 from my data(86) based on the procedure from Xhemi page and tksurfer lh inflated of both fsaverage and myatlas image is attached! it has shown that my atlas is smaller in general and larger in temporal lobe! I wonder if this is correct and I can proceed to compare left and right Hemispheres? -- Best regards, Amirhossein Manzouri

Re: [Freesurfer] Question about preproc-sess -no-subcort-mask
by Leila Reddy 01 Oct '13

01 Oct '13

Hi Doug, I don't think that could have happened as I only found out about the no-subcort-mask option yesterday (after I had done all the original analysis). I have just re-run all the analyses for the same subject with the same commands on the two machines (output of bugr for the 2 machines is below). I had deleted everything from this subject's bold directory except the f.nii and para.para files for each run, so that everything is re-analyzed. I get the same problem as before. I attach a screen capture of freeview with my bold/analysis.mni/mask.nii overlaid on freesurfer/average/mni305.cor.mgz from the two machines. As you can see, they are different. They only look the same if I re-run the analysis on snowleopardv5.3.0 with preproc-sess -no-subcort-mask.

Freeview questions
by Jonathan Holt 01 Oct '13

01 Oct '13

Simply to make sure, 1) Is there no way that one can edit two volumes simultaneously similarly to tkmedits aux+main volume brush? 2) When editing voxels in freeview, is there anyway to have the cursor behave the same way it does in navigation mode. That is, I'd like to be able to see exactly where I'm editing in all 3 views, rather than just the one I'm editing in. Best, Jon
