Cannot change min threshold in Configure Overlay Display TKSurfer
by Oana Georgiana Rus 02 Oct '15

02 Oct '15

Dear developers/users? When I load a *mgh.sig* file in *TkSurfer* and I go on *Configure Overlay Display* and want to change the *min Threshold on 1.3* or wathever number I can't edit or do that? did somebody encounter the same problem? How can you solve it? Thank You. -- Oana Georgiana Rus PhD Student Neuroimaging Center TUM-NIC Klinikum rechts der Isar Technische Universität München Einsteinstr.1 81675 München Raum 5.8 Tel. 089 4140 7971

Post-doctoral Positions in Affective Neuroscience at McLean Hospital/Harvard Medical School
by Poornima Kumar 01 Oct '15

01 Oct '15

Two post-doctoral positions are available within the Laboratory for Affective and Translational Neuroscience at McLean Hospital/Harvard Medical School, directed by Diego A. Pizzagalli, Ph.D. The laboratory is part of the Center for Depression, Anxiety and Stress Research (CDASR), a vibrant research center that embraces a multi-disciplinary approach to improve our understanding of the psychological, environmental, and neurobiological factors associated with depression, anxiety and related disorders across the lifespan ( http://cdasr.mclean.harvard.edu/) Currently ongoing studies in Dr. Pizzagalli’s laboratory focus on reward processing, stress responsivity, and executive functioning in a range of populations including individuals with major depression, mood spectrum disorders, as well as at-risk samples (e.g., offspring of parents with MDD; individuals with past MDD). These studies employ a variety of approaches, including high-density EEG, fMRI, PET, MRS, molecular genetics, and assays of hormonal/inflammatory markers, and often a treatment component (e.g., CBT). Opportunities will be available to pursue independent research and interdisciplinary collaborations across Harvard Medical School. Depending on research focus, candidates will have access to three research-dedicated human MRI scanners (3 T, 4 T) and one animal MRI scanner (9.4 T), as well as 128-channel EEG systems. A strong background in EEG/ERP or fMRI techniques is required, and clinical training is a plus. To apply, send a CV and a cover letter describing your research interests, and arrange for three letters of recommendation to be sent to David Crowley ( djcrowley(a)mclean.harvard.edu) Review of applications will begin immediately (expected start date: Summer 2016). McLean Hospital, which is an affiliate of Harvard Medical School, is an Equal Opportunity Employer. As an equal opportunity employer, McLean seeks qualified candidates for all posted employment opportunities without regard to race, color, age, religion, gender, national origin, disability or veteran status. McLean particularly welcomes applications from minorities, women, and persons with disabilities.

Re: [Freesurfer] Registering set of extracted hippocampus
by Chester Dolph 01 Oct '15

01 Oct '15

Hello, Rewording to clarify in case the wording was confusing. What I would like to do is to use each registered ROI for intensity based analysis. I am confused how to use Freesurfer to register and align about three axis. I understand there is variability with positioning the head within the scanner of MRI. I am guessing one solution might be to align each ROI centroid to the same location. This seems to be a trivial concept, but I was hoping there was a simple way of doing this using Freesurfer tools. I appreciate your time and help.

Re: [Freesurfer] Error Messages for Accessing Bin
by Bruce Fischl 01 Oct '15

can you try chmod a+x on one of them and see if it can then be executed? e.g.: chmod a+x /home/tle7/freesurfer/bin/mri_convert /home/tle7/freesurfer/bin/mri_convert and see if you get an error.

Re: [Freesurfer] niiRead(): error opening file SUBJECTS_DIR/Enzo_recon1/dti.nii
by Anastasia Yendiki 01 Oct '15

It's trying to find a file called SUBJECTS_DIR/Enzo_recon1/dti.nii. This is a relative path, i.e., it's trying to find it under the directory where you are currently cd'd. This seems like a problem with defining paths properly for unix, rather than a tracula problem per se. On Wed, 30 Sep 2015, andrea cristina Lima wrote: > I got the error below. Could you help me?

Hippocampal subfields
by von Polier, Georg Ferdinand Anto 02 Dec '14

02 Dec '14

Dear FreeSurfers, I am just finishing a paper using output from Hippocampal subfields and recognized that the current version has been deprecated. I am interested in volumes of the whole hippocampus. Are these volumes still valid and can you estimate when a new version will be available? Can you provide maybe a brief comment on the decision to deprecate the current version? Best regards, Georg

mri_surfcluster problem
by wangzhiwei3233 02 Dec '14

02 Dec '14

Hi Freesurfer experts, I just want to try cluster level threshold by cluster size, but not by mc simulation. So I tried the command like : mri_surfcluster --in sig.nii.gz --subject fsaverage --hemi lh --annot aparc --sign pos --minarea 50 --sum area50.pos.cluster.summary --o area50.pos.cluster.nii.gz --thmin 1.3 However, I found that the command did not set the non-cluster vertices to zero. The help of mri_surfcluster says that this command currently only supports paint (or w) format for input and output. I converted the sig.nii.gz to sig.w using mri_surf2surf --s fsaverage --hemi lh --sval sig.nii.gz --tval sig.w --trg_type paint. But command mri_surfcluster could not read the paint file. Could anyone help me? Thanks! Zhiwei
