Error from tractstats2table
by Adarsh Nellore 14 Feb '17

14 Feb '17

Hi there, I generated tractographies using the TRACULA pipeline and I'm not trying to generate the necessary statistics for them using tractstats2table. This is the command I'm using: tractstats2table --inputs /usr/local/freesurfer/subjects/control_data/ diffusion_tracs/Control200/dpath/lh.slft_PP_avg33_mni_flt/pathstats.overall.txt --overall --tablefile /usr/local/freesurfer/subjects/control_data/ diffusion_tracs/Control200/dpath/lh.slft_PP_avg33_mni_flt.All.table However, no matter what I change in this command, whether it be parameters or syntax, I get the following error: File "/usr/local/freesurfer/bin/tractstats2table", line 138 print 'ERROR: inputs are not specified' ^ SyntaxError: Missing parentheses in call to 'print' I'd really appreciate any advice on how I may be able to get past this error as soon as possible. Thanks a lot!

Control Points editing
by Andrea Gerardo Russo 14 Feb '17

14 Feb '17

Hi FreeSurfer experts, I have some questions (maybe trivial) about Control Points editing. 1) Following the guide in your website and exploring your tutorial subject "cp_before" I understood that a Control Point has to be placed in a region that is definitely white matter but the standard recon-all process has classified as gray matter. However in the section "General Tips" you suggest that a Control Point has not to be placed in a tissue different from the white matter, and in other questions posted on the this mailing list several scientists said that they place Control Points in the white matter voxels with an intensity lower than the 110 to adjust the local intensity. I'm a bit confused. What is the correct strategy? 2) I noticed that a Control Point can adjust the white matter surface in its neighborhood, but it can create unpredictable changes in surfaces in other regions. How is it possible? 3) What kind of index can I use to test the reliability of Control Point editing? In a test-retest protocol, considering a single subject, I noticed that although the Control Point positioning improves the FreeSurfer surfaces there is an increase of the covariance in the cortical thickness measurements between scans after the editing. How can I interpret this results? Best regards Andrea Gerardo Russo

Yes, I set FREESURFER_HOME variable as '/Applications/freesurfer’, which I installed freesurfer v6. I attached recon-all.log file below. I can see 'build-stamp.txt: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c’ in log file. Is there anything to check more?

Postdoctoral Position/Developmental Neuroimaging
by emma jane 13 Feb '17

13 Feb '17

The Program for Translational Research on Adversity and Neurodevelopment (P-TRAN) at The Pennsylvania State University is seeking a qualified postdoctoral researcher with expertise in human brain imaging, specifically magnetic resonance imaging (MRI)) with children and adolescents. This position is supported by a recently awarded NICHD Center Grant (i.e., a CAPSTONE Center for Multidisciplinary Research in Child Abuse and Neglect; PI: Dr. Jennie Noll) and will be based in the Child Maltreatment Solutions Network (http://solutionsnetwork.psu.edu/) and the Prevention Research Center (www.prevention.psu.edu) both of which are located on the University Park campus in State College, PA. The primary responsibility of this position will be to provide neuroimaging research support (e.g., experimental design, implementation and data analysis) to a longitudinal project that will consider the biological embedding of child maltreatment in multiple biologic systems (e.g., neuroendocrine, autonomic, genetic, epigenetic, immunologic) and the impact of embedding on health outcomes, including neurodevelopmental trajectories. Candidates must have a PhD in psychology, neuroscience, or an allied field, or have completed all requirements for a PhD by the time of appointment. Applicants must have expertise in human subjects MRI, preferably with developmental cohorts. Preference will be given to those candidates with experience working with children who have experienced maltreatment or other high-risk groups. The successful candidate will be expected to contribute to experimental design and co-ordination of the neuroimaging aspects of the project and data analysis. Candidates must demonstrate expertise in functional and structural MRI analysis methods using standard processing packages (e.g., SPM, AFNI, FSL, Freesurfer etc.) and experience with longitudinal and complex datasets would be advantageous. The postdoctoral researcher will also be expected to contribute to manuscript preparation and presentation of study-related outcomes at key scientific meetings. Extensive mentorship will be provided to the successful candidate in order to facilitate transition to an independent research career. This position will provide an opportunity to interact with several vibrant research communities at Penn State, including the Social Sciences Research Institute (www.ssri.psu.edu) and the Social, Life and Engineering Science Imaging Center (www.imaging.psu.edu) among others. The initial appointment will be for one year, with the possibility of renewal in subsequent years. Salary and benefits are based on NIH guidelines, commensurate with experience and qualifications. Interested candidates should upload a CV, cover letter, statement of research interests, and 2-3 relevant publications. In addition, applicants should arrange for 3 professional references to be submitted separately to Dr. Emma Jane Rose (Associate Director for P-TRAN) at emmajanerose(a)psu.edu. Review of applications will begin immediately and will continue until the position is filled. Applications received by March 24, 2017 will be given full consideration, although the position will remain open until filled. The expected start date will be between April and June 2017. For further information about this appointment, please contact Dr. Emma Jane Rose at emmajanerose(a)psu.edu or 814-865-0114 <(814)%20865-0114>. Apply online at https://psu.jobs/job/69051 CAMPUS SECURITY CRIME STATISTICS: For more about safety at Penn State, and to review the Annual Security Report which contains information about crime statistics and other safety and security matters, please go to http://www.police.psu.edu/clery/, which will also provide you with detail on how to request a hard copy of the Annual Security Report.

hippocampal subfields analysis command
by Rizvi, Batool 13 Feb '17

13 Feb '17

Hi, I'm having trouble getting any output from the hippocampal subfield analysis command. I entered in: quantifyHippocampalSubfields.sh T1 hippo.txt /path/to/my/subjects/freesurferfolder I tried both ways of having the environmental variable subjects directory defined to the freesurfer folder of the subjects (used *'s here for subjects and their freesurfer folder), but it still gives no output. It just says: Gathering results from subjects in: /path/to/my/subjects/freesurferfolder Using the suffix name: T1 And writing them to: hippo.txt What am I doing wrong here? Thanks so much! Batool

Hi Bruce, All output generated is redirected to a temporary log file by me. Fortunately, it is still available and when I look at it I see what happened: it doesn’t find Matlab runtime in the FreeSurferv6 directory. I’m sorry about this, I just have to copy the MCRv80 from FreeSurferv6b to v6 and it will do the hippocampal subfields segmentation.

Writing FSL compatible ascii files
by Melanie Ganz 13 Feb '17

13 Feb '17

Dear all knowing list, we are just playing around with the MSM code within FSL and noticed that if we try to convert surface data to ascii like e.g. this mri_convert --ascii funcdata.nii funcdata.asc it produces an ascii file that looks good when opened in a text editor, but doesn't seemt o be able to be read in by FSL. But if we just read and write the nii file to text in matlab this works. We think the issue is created by the type of end of line character used by FS. Does anyone else have experience with this? Could this be an idea to update to make the compatibility with FSL easier?
