Disjointed thalamic nuclei segmentation
by Niels Bergsland 10 Oct '18

10 Oct '18

External Email - Use Caution Hi Eugenio, Thank you again for the fantastic thalamic nuclei segmentation tool! I'm going through and QC'ing a batch of subjects that were processed through the pipeline. Data was originally processed with freesurfer-6.0.0 and then processed through the thalamic nuclei stream (dev-20180818-e30e6f9). I have found that for some cases, there are some isolated patches of voxels that are disconnected and seemingly in the wrong place. I've noticed it primarily for the MDm and my impression is that it tends to happen more in the right hemisphere. I've attached a sample image to show you what I mean. The red cross has been placed on a set of these voxels. It is not the case that they are connected in 3D. Any input is appreciated and thanks again! If it can be useful, I'm happy to upload the data -Niels

Postdoctoral Fellowship Positions in Traumatic Stress Disorders
by Emma Brown 10 Oct '18

10 Oct '18

External Email - Use Caution POSTDOCTORAL FELLOWSHIPS IN TRAUMATIC STRESS DISORDERS Collaborating research groups at the VA Boston Healthcare System anticipate up to two NIMH-funded postdoctoral fellowships to begin by September 2, 2019. These two-year training positions are designed to prepare researchers for academically-oriented careers in the psychology and neurobiology of stress-related disorders. Previous fellows have launched successful careers in universities and academic medical settings. Candidates with backgrounds in neuroimaging and/or genetics are encouraged to apply. The fellowship program is affiliated with Boston University School of Medicine and is located primarily at the Jamaica Plain Campus of VA Boston. Affiliated centers include the Behavioral Science and Women's Health Sciences divisions of the National Center for PTSD, the Translational Research Center for TBI and Stress Disorders, the Neuroimaging Research for Veterans Center, the VA National Center for PTSD Brain Bank, and the Center for Healthcare Organization and Implementation Research. These programs offer outstanding resources including existing datasets, technical support personnel, well-equipped laboratories, advanced computing facilities, and a broad range of professional expertise. The anticipated salary and benefits package is competitive, and supplemental funds will be available to support further coursework and other educational opportunities, conference attendance, and travel. The program offers training in several core areas. Candidates may contact the following program leaders prior to application for more information about the specific cores:Clinical Neuroscience and Neuroimaging(David Salat salat(a)nmr.mgh.harvard.edu) Molecular Biomarkers and Genetics (Mark Miller: mark.miller5(a)va.gov) Assessment, Diagnosis, and Epidemiology (Brian Marx:brian.marx@va.gov), Treatment Development and Optimization (Denise Sloan:denise.sloan@va.gov), and Implementation and Dissemination (Terry Keane:terry.keane@va.gov). Fellows will have the opportunity to participate in ongoing research projects conducted by program faculty, initiate independent research projects, conduct secondary analyses on existing data sets, prepare grant applications to federal and other funding agencies, and learn about all aspects of laboratory management. Each fellow will have a senior faculty member assigned to serve as a primary mentor. For license-eligible clinical psychology fellows, arrangements are available outside the program to provide direct clinical services to patients under the guidance of a clinical supervisor. Materials will be reviewed and interviews arranged on a first-come basis. Preliminary applications should include a statement of interests and goals, a curriculum vita, and three professional references that should be sent directly by the recommendation writer. Applicants must be U.S. Citizens and have completed all requirements for their doctoral degree prior to starting the program. Minority candidates are strongly encouraged to apply. Applications should be submitted electronically no later than December 3, 2018 to Denise Sloan, Ph.D. (denise.sloan(a)va.gov) The VA Boston Healthcare System is an equal opportunity employer.

Fwd: Hippocampal-Amygdala subfields error
by Miguel Ángel Rivas Fernández 10 Oct '18

10 Oct '18

External Email - Use Caution Hi everyone, Here a question and an answer of FreeSurfer experts that would be for interest. - Could there be any difference in accuracy when the recon-all is executed on two Mac computers that have a different processor? that is, it is preferable to execute the recon-all of all the subjects in the same computer?. Sorry for this absurd question but I would be sure about this. - *Regarding the second question: it is a really good one. Would you mind posting it on the FreeSurfer list?

Extract individual vertex thickness values from cortical parcellations
by lindsay hanford 09 Oct '18

09 Oct '18

External Email - Use Caution Hello Freesurfer Community, I am looking for a way to extract thickness values at the level of each vertex from Freesurfer atlas-based parcellated regions (aparc.annot), or more generally lobes. Is this possible? Using mri_segstats I know it is possible to get more general metrics such as min, max and average thickness values, and # of voxels. Is it possible to use an annot file to read out the raw thickness values? This post was the closest I could find to answering my question, however, this was at the group level and not specified for parcellated regions. https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2012-January/022097.… Thank you in advance, Lindsay -- *Lindsay Hanford, PhD* *The Buckner Laboratory* *|* *Harvard University*

very bad result using "mris_ca_train" and "mris_ca_label"
by Maedeh Khalilian 09 Oct '18

09 Oct '18

External Email - Use Caution Dear Dr.Bruce Fischl Thank you very much for your great sense of responsibility. Sure, i have sent you a zip file named "Maedeh_results"(it was a rather big sized one so i had to send it through Wetranser). Hope you have received it. However, a general question is that, according to freesurfer help the required arguments for "mris_ca_train" are : mris_ca_train [options] <hemi> <canon surf> <annot file> <subject 1> <subject 2> ... <output file> as it seems it gets one surf file(e.g sphere.reg),and one annotation file, but several subjects...so what does this surface file refer to?should i make an average of all subjects' .reg files? and also for the annotation file ! just one .annot is enough or i have to make an average of several annotation files? if yes, how should i do that? i would be grateful if you could help me. Best regards Maedeh,
