Freesurfer6.0 failure
by Naka Beguedou 22 May '18

22 May '18

Hello, I allow myself to send you this mail in order to have some informations. we have a problem concerning the segmentation of FREESURFER6.0 Indeed for T1image of one subject, the surface segmentation(figure1) is accurate but there is failure on the cortical segmentation(figure2) of the right hemisphere for the free surfer 6.0. For that subject, we relaunched the free surfer6.0 , but still the same problem. Here is the command we used to relaunch the free surfer6.0 for that subject: recon-all -all -FLAIR FLAIR/FLAIR_585.nii.gz -i T1/T1_585.nii.gz -brainstem-structures -3T -contrasurfreg -qcache -subjid SHARE0585_2 -sd /scratch/alaurent006/freesurfer_end -FLAIRpial What can we do about it? Thanks

POST-DOCTORAL FELLOWSHIP IN NEUROIMAGING

External Email - Use Caution POST-DOCTORAL FELLOWSHIP IN NEUROIMAGINGTHOMAS JEFFERSON UNIVERSITY/ SIDNEY KIMMEL MEDICAL COLLEGE, PHILA., PA. The Department of Neurology at Thomas Jefferson University/Jefferson Medical College has an opening for a Two-Year Postdoctoral Research Fellowship in Neuroimaging focusing on both clinical brain mapping and primary cognitive neuroscience investigations. The emphasis in our neuroimaging program is on cognitive and behavioral network organization and plasticity in neurologic disorders such as epilepsy. The lab focuses on the use of advanced network neuroscience measures to understand seizure networks and cognitive reorganization in epilepsy, and has had recent publications in Brian, Neurology, and Epilepsia, with some also prompting complimentary peer reviews. The lab is part of the Jefferson Comprehensive Epilepsy Center, an internationally-known epilepsy surgery program. Presurgical brain mapping studies are undertaken (MRI volumetrics, task-fMRI, resting state functional connectivity, diffusion imaging, neuropsychological assessment, electrophysiology/electrocortical stimulation) as well as post-surgical neuroimaging studies investigating clinical, cognitive, and behavioral outcomes. The pre-surgical brain mapping studies are conducted on a regular basis, utilized in image-guided surgery, and then made available for research. Studies in brain recovery and the cognitive reorganization of language and memory functions are emphasized, utilizing rich multi-modal datasets for the investigation of both cognitive and pathologic (e.g., seizure) networks. Thomas Jefferson University provides a high-level interdisciplinary research environment with grand rounds, seminars, case conferences, and opportunities to collaborate with faculty across departments such as neurosurgery and radiology. Successful applicants must have a strong background in image processing and analysis using programs such as MATLAB, SPM, Freesurfer, and FSL with a strong interest in clinical neuroimaging and cognitive neuroscience. Applicants must have a Ph.D. or MD in neuroscience, biomedical engineering, statistics, neurology, neuropsychology, radiology, or related field. Interested applicants should send a CV and cover letter stating experience and interests, 2-3 peer-reviewed publications. Anticipated start date is 7/1/18, but is flexible. Contact: Joseph I. Tracy, Ph.D., ABPP(CN). Director, Cognitive Neuroscience and Brain Mapping Laboratory, Thomas Jefferson Univ./Sidney Kimmel Medical Coll., Jefferson Hospital for Neuroscience, 901 Walnut Street, Suite #447, Phila., PA 19107, phone:#215-955-4661, e-mail: joseph.tracy(a)jefferson.edu.

Re: [Freesurfer] FS_Fast preproc-sess - bbregister misalignment
by Douglas N. Greve 21 May '18

21 May '18

The problem appears to be that your data are not really T2* weighted in that the intensity of cortex (about 830) is less than that of WM (about 862). Try running preproc-sess with -t1 to indicate to bbregister that your data are t1 weighted.

Error results mris_make_surfaces

External Email - Use Caution Hello, experts I have a problem with the results of mris_make_surfaces to pial and white matter surfaces. I am working with high resolution (0.75x0.75x0.75) monkey images, mris_makes_surfaces finish without errors but the surfaces have notches, I attach an image as an example of the error. This is the line that I am using mris_make_surfaces -whiteonly -noaparc -noaseg -mgz -T1 brain.finalsurfs subject lh. The error only appers with mris_make_surfaces, the segmentation of wm and ?h.orig looks good. Thanks a lot Pam [image: Screenshot from 2018-05-18 14:29:12.png]

mris_fwhm
by Eduard Vilaplana Martinez 21 May '18

21 May '18

External Email - Use Caution Dear freesurfer experts, I would like to ask you about the mris_fwhm script. What does the flag "--mask" exactly do? Suppose I would like to compute the effective smoothness of an mri dataset. Some subjects have zeros in some vertices, but instead of using the prune option, I would like to use all the available signal, so I have to use a different mask for every subject. Would the option mask do the job in that case and would accept the multidimensional mask? Or rather the "--mask" option expects for a single (not multidimensional) mask? Any insight would be greatly appreciated. Thanks in advance, Eduard Vilaplana.

gcs and gca to coordinates
by Tim Hahn 18 May '18

18 May '18

External Email - Use Caution Dear all, thanks for building and maintaining freesurfer. It's really a great tool. My question is very simple: I have three Freesurfer Atlas files (lh and rh curvature.buckner40.filled.desikan_killiany.2010-03-25.gcs and RB_all_2008-03-26.gca) and would like to either get all coordinates in a given area and/or a nifti/img. I realize that the gcs and gca files contain much more information. However, I just need the location information and ROI name for a meta-analytic approach based on the literature. Is there any way to get this information? Thanks a lot! Cheers, Tim
