TWO Postdoctoral Research Associate Positions Opened
by Corbo, Vincent 20 May '16

20 May '16

The Translational Research Center for TBI and Stress Disorders (TRACTS) at VA Boston Healthcare invites applications for two positions as Postdoctoral Research Associate in brain imaging of Veterans. The TRACTS conducts a prospective longitudinal cohort study and has recruited over 500 Veterans from the greater Boston area. The research employs a multimodal approach to examine the effects of prevalent conditions including traumatic brain injury (TBI), posttraumatic stress disorder (PTSD), chronic pain, depression, and other military-related disorders on the health, behavior, and neural function of Veterans. This project is conducted at the Jamaica Plain campus of the VA Boston Healthcare system, and includes behavioral testing, clinical interviews, and neuroimaging. We have an opening for two Postdoctoral Researchers focused on the neuroimaging aspects of the study, which includes magnetic resonance imaging (MRI) of brain structure and function (diffusion tensor imaging, arterial spin labeling, functional connectivity, etc.). We are seeking highly motivated, proactive candidates who are willing to learn new skills and contribute to multiple projects as part of a larger team. We are seeking a postdoctoral research associate for the neuroimaging portion of the TRACTS study, as well as a second postdoctoral research associate for a project that will use MRI and positron emission tomography (PET) of dopamine receptor mapping in individuals from the TRACTS cohort with a history of binge drinking. This project will take place at the Jamaica Plain campus of the VA Boston Healthcare system and at the Athinoula A. Martinos Center for Biomedical Imaging located in Charlestown. Successful candidates of both positions will have major roles in the primary research project including management of the technical/imaging aspects of the study as well as project management/administration, and training and mentorship of research assistants on the project. The researchers will contribute to all aspects of the work including (but not limited to) participant enrollment, characterization, operation of the MRI (and PET) scanners, data management, organization, processing and analysis, manuscript preparation and publications. The researchers will work in close collaboration with clinical neuropsychologists, cognitive neuroscientists, and research assistants, and will likely be involved in multiple projects. There will be significant training and collaboration with the Neuroimaging Research for Veterans (NeRVe) Center, also at VA Boston. Individuals with PhD or equivalent in computer science, biomedical engineering, neuroscience, psychology, or related fields are welcome. Prior experience in brain imaging research and use of neuroimaging software (FSL/Freesurfer/AFNI/SPM) is required. It is additionally expected that individuals will devote time to training to learn new image processing and analysis procedures while in this position. The ideal candidate will have strong computer skill, including expertise in Unix/Linux operating systems, MATLAB, shell scripting, and statistics, and strong prior experience in brain imaging research. The positions also require strong organization, communication, and writing skills. A minimum of a two-year commitment (with opportunity for a longer position) is required, and positions are available beginning immediately. US Citizenship is required. Salary will be consistent with levels in accordance with the Boston VA Medical Center policies for postdoctoral researchers. Compensation includes full staff benefits, including health insurance, and vacation time. Interested candidates should send a cover letter and copy of their CV to Gino Jackson, Administrative Officer, at gino.jackson(a)va.gov . ____________________________ Vincent Corbo, Ph.D. Postdoctoral fellow Translational Research Center for TBI and Stress Disorders (TRACTS) Neuroimaging Research for Veterans (NeRVe) Center Veterans Affairs Boston Healthcare System Boston University School of Medicine

optimal T1 protocol
by Jason Tourville 20 May '16

20 May '16

Hello freesurfer experts, Do you have a recommended "optimal" T1 protocol on Bay 1 for cortical reconstruction? For the past couple years, we've been using the 'tf1_mgh_multiecho_1mm_iso" protocol which has PAT = 2 and a TA = 6:02. 􀀈􀀎 I'm wondering if a faster option at the same resolution is now available that is recon-approved? For instance, a multi-band option? Thanks for any feedback, Jason

Cluster Color
by Timothy Hendrickson 20 May '16

20 May '16

Free Surfer Support, I have been using the command line version for group analysis since my data set has too many factors for QDEC. There are a few things that I enjoy about QDEC that I wish I could incorporate into the command line. 1) In QDEC the cluster color is not set arbitrarily, but rather based on significance. Is there any way to have the cluster color be set based on significance at command line? Is there a way to restrict the available colors that the clusters can be set as? Occasionally, cluster colors are a very similar color to the inflated underlay making it difficult to determine the outline of said cluster. 2) In QDEC one is able to visualize a scatter plot for a particular cluster. Is there any way to do this via the command line option? Thank you, -Tim Hendrickson -- Timothy Hendrickson Department of Psychiatry University of Minnesota Mobile: 507-259-3434 (texts okay)

segfault using brainstem module from dev version
by Vincent Beliveau 20 May '16

20 May '16

Hi list (and Eugenio), I've ran the brainstem module from the dev version on some data processed with FS v5.3. The module created some great segmentations of brainstem but when taking a closer look at the log file, there is 2 seg faults which occur when calls to mri_robust_register are made, with the following output (full log attached, see line 319 and 371): /data1/vbeliveau/software/freesurfer-Linux-centos4_x86_64-dev-110516/bin//mri_robust_register: line 3: 36835 Segmentation fault mri_robust_register.bin "$@" /data1/vbeliveau/software/freesurfer-Linux-centos4_x86_64-dev-110516/bin//mri_robust_register --mov imageDump.mgz --dst /indirect/data1/vbeliveau/atlas/proc/MR/recon_final/f5249_GD/tmp/BS_T1based//BS-DE-binaryMask_autoCropped.mgz -lta trash.lta --mapmovhdr imageDump_coregistered.mgz --sat 50: Segmentation fault mv: cannot stat ?imageDump_coregistered.mgz?: No such file or directory I'm curious about how is this affecting the overall process, as otherwise everything appears to be working smoothly.

Question about group analysis
by Josh Gray 20 May '16

20 May '16

Hello, I've got a very basic question related to group analysis. If I want run a correlation of voxels in the cortex with a variable *controlling *for another continous variable, how do I do this. I know how to run them both in a GLM simultaneously by coding the matrix 0 1 1, however, how do I look at the first variable after controlling for the other? Here is an example of my current fsgd input (I want to control for income): GroupDescriptorFile 1 Title MyTitle Class Class1 plus blue CLASS Class2 circle green SomeTag Variables impulsivity income Input subjid1 Main 10 100 Input subjid2 Main 20 200 etc. -- Graduate Student Psychology Dept. - Clinical Program Experimental & Clinical Psychopharmacology Laboratory University of Georgia
