view retinotopy results in version 5
by Y.V. Jiang 27 Mar '13

27 Mar '13

Hi, I was able to view retinotopic mapping results using rtview in version 5. However, the display was on the inflated surface. Is there a way to view the results on the flattened occipital map, similar to version 4's surf-sess -flat? Thanks! -Yuhong

surf2vol
by Daniel Lumsden 27 Mar '13

27 Mar '13

Bruce Many thanks - that's given me a lot more guidance. Following the help, i've put together the command below: mri_surf2vol --hemi lh --template <path to>/orig.mgz --outvol <path to where I want the file>/leftfrontallobe.nii.gz --surfval <path to>/left_frontal_lobe.gii --fillribbon --volregidentity mov07 Where mov07 is my subjid and left_frontal_lobe.gii is the surface I've generated from the label files to run in probtrakx. This command runs, but produces and empty nifti file. I've changed the output to .mgz with similar effect. I've substituted the rawavg.mgz file for the orig.mgz file, and tried both .nii.gz and .mgz versions of both files and still get an empty output file. The subject is in my $SUBJECTS_DIR. Is there a way to check the .gii files? I generated them using label2surf, having used mris_convert to convert the lh.white and rh.white files from the surf folder for my subject to lh.white.asc and rh.white.asc. Thank you again for your help.

Fwd: Cortical thickness in average space
by Rafa X 27 Mar '13

27 Mar '13

Thanks Bruce for your answer, as you asked I'm forwarding this question to the list in case any other can answer this. We already have the surface generated by mri_preproc, now we are trying to read it using the matlab function read_mgh. It returns a 4-D matrix, how can we interpret this data to get the cortical thickness values at each vertex of every subject?

question regarding creating Brodmann area
by Ji Won Bang 27 Mar '13

27 Mar '13

Dear. freesurfer users. I'm trying to make a label for Brodmann area 44. According to the freesurfer manual, I've run, recon-all -s subjid -ba-labels However, it says Flag -ba-labels unrecognized. I'm using freesurfer version 4.5.0. By default, recon-all is supposed to create Brodmann areas under label directory. However, inside the lable directory, I see only aparc.annot.a2009s.ctab aparc.annot.ctab lh.aparc.a2009s.annot lh.aparc.annot lh.cortex.label rh.aparc.a2009s.annot rh.aparc.annot rh.cortex.label Please leave me any comment!! I appreciate it a lot! Best regards, Ji Won Bang

memory allocation errors on Snow Leopard running dmri_train

Hi FS users, I've tested the newer Tracula FS 5.2 on Snow Leopard and ran into errors. The 5.2 recon-all of T1 was finished ok.

Problems with recon-all--won't generate wm or surf files
by Hayley Dorfman 27 Mar '13

Hello, I've been having problems with recon-all for only 1 of my 50 subjects. Recon-all is failing somehow before white matter or surf files are generated. The T1 and nu.mgz files look fine.

CT as covariate
by Rafa X 27 Mar '13

27 Mar '13

Dear Freesurfers I will introduce the mean cortial thickness as covariate into my statistical model, but I'm wonderind which way will be the best. To get the cortical thickness in individual space, or in AVG space? Thank you all in advanced, Rafa.

June course on structural and functional connectivity at the Martinos Center
by Anastasia Yendiki 27 Mar '13

27 Mar '13

Dear Freesurfistas - This new course, offered at the Martinos Center right before the OHBM meeting, may be of interest to some of you. There are some open spots left. For info on how to register and a tentative schedule, see the web page at the end of the announcement. a.y --- STRUCTURAL AND FUNCTIONAL BRAIN CONNECTIVITY AS REVEALED BY MRI Dates: June 3-7, 2013 Themes: Resting State Functional Connectivity and DTI/DSI/Tractography Location: Martinos Center for Biomedical Imaging of the Massachusetts General Hospital; Boston/Charlestown Massachusetts Program Director: Robert L. Savoy In December 2012 the Martinos Center for Biomedical Imaging introduced a new, 5-day program on functional and structural connectivity using MRI. The next edition of this program will be held June 3-7 (two weeks prior to the Organization for Human Brain Mapping annual meeting). There is likely to be an additional program in 2013, to be held near the end of October or early November, 2013. Issues associated with connectivity in the human brain are of increasing importance, as reflected in the large number of abstracts, research articles, and even entire journals devoted to this area, as well as the increased emphasis on lesions within the white matter as being a source of many neuro-psychiatric disorders. MRI has proven to be a valuable tool for examining connectivity both in terms of the coordinated activities of neural networks (using BOLD-based fMRI data collected during rest and during tasks) and also in terms of the structural anatomy of white matter pathways of the brain (using Diffusion Tensor Imaging (DTI), Diffusion Spectrum Imaging (DSI), and tractography programs to analyze and visualize the resulting data). Participants will learn about the technical challenges in acquisition, data processing and visualization of brain networks via the data from fMRI during the so-called resting state, but also available during experimenter-initiated cognitive tasks. Participants will also receive a firm grounding in the power and limitations associated with using diffusion-sensitive MRI to detect and organize the anatomical structure of white matter tracts in the living human brain. The primary goal of this program is to give researchers and clinicians a good start for their investigations using these tools. In that sense, it serves a purpose analogous to that of the Functional MRI Visiting Fellowship Program (fMRIVFP) also offered at the Martinos Center, except that the domain will be structural and functional connectivity of myelinated fiber tracts within the living human brain. The active component of the program will be the use of software tools to promote quality assurance in the data, detect outliers and other problematic attributes of the data, optimize data acquisition, and flexibly visualize the data in the service of asking and answering specific questions. Participants will be expected (though not required) to bring a suitable laptop computer for engaging in the hands-on exercises of the program. There will also be a section on the Connectome MRI Machine that uses exceptionally strong gradients to enhance data acquisition of strutural and functional images. The core faculty is drawn from the staff of the Athinoula A. Martinos Center (of the Massachusetts General Hospital and Massachusetts Institute of Technology) and affiliated faculty from Harvard University, McLean Hospital and other local institutions. Guest lecturers (at the Dec, 2012 program) included faculty from the Child Mind Institute of New York, NIH, Stanford University, The Donders Institute, the University of Cambridge and others.

Incomplete and poorly formed tracts
by Susan Kuo 27 Mar '13

27 Mar '13

Hi FreeSurfers and Anastasia, TRACULA is working great for me, generating tracts for a sample of 20 subject brains I'm working with. However, for 3 of the brains, I'm receiving incomplete and poorly formed tracts. I've re-run trac-all at least 2x on each subject in case there was a mistake in my original configuration. However, I am reproducing the same results. Does anybody have an idea why I would see these "spotty" tracts? Thank you for all your help! -- Susie Kuo NIH
