Problems with hippocampus subfields segmentation
by Lukas.Scheef＠ukb.uni-bonn.de 14 May '13

14 May '13

Hi FreeSurfer Experts! I try to run the hippocampus subfield reconstructions. Because I already run reconall -all on my subjects (without errors, all necessary manual edits were done) I try to reconstruct only the hippo-subfields: recon-all -s my_subjects -hippo-subfields The shell output is given below... Any ideas?

Re: [Freesurfer] Show curvature and show overlay
by Irina Simanova 14 May '13

14 May '13

Dear freesurfer experts, I am new to freesurfer and I want to project my single-subject MVPA (obtained in Matlab) results on a single-subject brain surface with curvature. I followed the steps from the tutorial: - reconstructed individual subject's brain surface - wrote my MVPA results map as a nifti image - resampled the map onto the surface Now I want to visualize it. The tutorial (http://ftp.nmr.mgh.harvard.edu/fswiki/FsTutorial/NavigateResampledParametri…) suggests to use qsurfer, however I don't seem to have this command. I tried to open the surface with tksurfer and then load the overlay, as described in the tutorial on visualization. However, when I open an inflated surface file, both buttons "show overlay" and "show curvature" are not active (though I have the .sulc file in the /surf). This is probably a very simple question, but I am stuck here. I would appreciate any advise on how to do the visualization: either from the command line or with tksurfer tools. thank you, kind regards, Irina Simanova

hematoma problem
by LAOUCHEDI MAKHLOUF 14 May '13

14 May '13

hi I am working on severe TBI and most of them suffer from large hematoma and according to litterarture, the apearance on T1 changes accordind to the stage of the trauma, from 3days (early suba acute) to 14 days (late subacute) the T1 signal from hematoma is Hyperintense and after that it becomes hypointense. I want to know how freesurfer, especially the skull stripping or brain extraction step, deals with these two cases (i have both in my database). I want later to extract the cortical ribbon for tractography use. Thanks

using T2* weighted scans to assist with dura stripping in a GE scanner?
by Katie Surrence 13 May '13

13 May '13

Dear Freesurfer gurus, At the course, André van der Kouwe mentioned in his morphometry methods talk that T2* weighted contrast from MEMPRAGE could be used to further seperate dura from cortex, as also discussed in this paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408694/. We have a GE scanner in our lab. The internet suggests that a Multi-echo FSPGR/FGRE exists. Would this be the analog? Would it work the same way? Could you also use these images with the mris_make_surfaces command? Thanks very much for your insight -- and I enjoyed the course! /Katie Surrence -- Research Coordinator Social Cognition Laboratory New York State Psychiatric Institute

Resting state analysis
by Efrat Kliper 13 May '13

13 May '13

Dear freeSurfer expert, I am trying to perform whole brain functional connectivity analysis Is there a wiki for resting state analysis? I have only found this wiki page https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorialV5.1/FsFastPreProc So far I have run the following commands: preproc-sess -s TB_482 -fsd Rest -stc odd -surface fsaverage lhrh -mni305 -fwhm 5 -per-run What is the next step? Should I use the mkanalysis-sess command? (mkanalysis-sess -TR 3 -fsd Rest -stc odd -surface fsaverage lh -mni305 2 -fwhm 5 -analysis TB_482_lh -notask)? Running this command it seems to create only an output file with a list of information and nothing more, what am i doing wrong? In addition for resting state analysis, band filter of 0.01-0.08Hz needs to be done. How do i do that and to which of the output files? I don’t find any record about that either. Thanks in advance, Efrat

LGI radius on outer surface ?
by Gregory Kirk 13 May '13

13 May '13

Hello Im preparing an LGI(local gyrification index) manuscript and seems i don't know the default radius that is used for the circular region defined on the outer surface that the boundary of is then projected onto the pial surface to get the corresponding pial region ? hope im clear, not the radius of the closing operator. thank you Greg

parcellation boundaries freesurfer atlas
by Oort-4, J. van 13 May '13

13 May '13

Dear freesurfer mailing list, I have got a question with regard to the freesurfer parcellation. I'm using the atlas with 68 cortical areas. I would like to determine where to locate anatomical and functional areas in this atlas. In this way I would like to locate the areas that are involved in processing auditory and visual information. I can't find any article that describes the anatomical boundaries that are used in the parcellation, or which Bradmann area is included in which parcel. Could You recommend an article or other resource where I could find this information? greetings, Jasper van Oort ------------------------------------------------------------------------------ De informatie opgenomen in dit bericht kan vertrouwelijk zijn en is uitsluitend bestemd voor de geadresseerde.

Usage of --area option in estimating the vertex-wise maps of surface area
by Xinian Zuo 13 May '13

13 May '13

Hello Doug, I am doing some association studies between functional measures and surface area. In using mris_preproc, there is an option --area. Does this do sth similar to that as Winkler et al. (2012)? Winkler et al., 2012. Measureing and comparing brain cortical surfacearea and other areal quantities. Thank you very much. -- Xi-Nian Zuo, Ph.D of Applied Mathematics (http://lfcd.psych.ac.cn) Google Scholar Citations: http://scholar.google.com/citations?user=a3-gVGMAAAAJ&hl=en
