Hi Anastasia Thanks for your quick reply. I’ve changed the command and I got one step further. Now I get another error: mv -f /Users/rdpauw/Desktop/SUBJECTS_FS/T1/INP_080_LISA_V_1/dmri/dwi_orig_flip.mghdti.bvecs /Users/rdpauw/Desktop/SUBJECTS_FS/T1/INP_080_LISA_V_1/dmri/bvecs mv: rename /Users/rdpauw/Desktop/SUBJECTS_FS/T1/INP_080_LISA_V_1/dmri/dwi_orig_flip.mghdti.bvecs to /Users/rdpauw/Desktop/SUBJECTS_FS/T1/INP_080_LISA_V_1/dmri/bvecs: No such file or directory Darwin ge24p176.ugent.be 13.3.0 Darwin Kernel Version 13.3.0: Tue Jun 3 21:27:35 PDT 2014; root:xnu-2422.110.17~1/RELEASE_X86_64 x86_64 trac-preproc exited with ERRORS at Mon Aug 25 14:23:03 CEST 2014 Somehow the folder bvecs was not created? Regards, Robby Hi Robby - It looks like in your config file "setbveclist" is one word, instead of "set bveclist". This may be why you're getting the "Badly placed ()'s." error at the very beginning of your trac-all output. And it would explain why it can't find the files.

Correlation of symptom severity and significant clusters
by Katharina Zech 25 Aug '14

25 Aug '14

Dear all, I want to do a correlation of significant clusters found after full monte-carlo simulation and symptom severity of patients affected with obsessive-compulsive disorder (OCD). The aim is as follows: First, to see whether the severity of symptoms correlate with the degree of structural brain alterations. Second, whether the degree of structural brain alterations shows a correlation with specific subtypes of OCD. As I run the full monte-carlo simulation, the significant clusters pop up in tksurfer. So could you explain to me the following steps? Thanks a lot! Katharina

BBRegister Patch
by Zamroziewicz, Marta Karolina 25 Aug '14

25 Aug '14

Good morning! Is the bbregister patch available yet (original email below)? Thank you for your time and assistance! Marta Zamroziewicz MD/PhD Candidate Decision Neuroscience Laboratory University of Illinois Urbana-Champaign mzamro2(a)illinois.edu<mailto:mzamro2@illinois.edu> 815-980-3882 This email is related to the archived “bbregister and FLAIR” email chain posted by Kayle Sawyer on 5/23/2014 (http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg36117.html) We have also been registering with FLAIR scans, and have run into a problem with approximately half of our subjects. Recon-all completes successfully but a bad registration step leaves our MPRAGE and FLAIR scans misaligned. I’ve attached two screenshots, the first of which shows a bad registration and the second of which shows a good registration. Per your previous suggestion, we ran bbregister using the following flag: bbregister --s SLOTS007 --mov flair.mgz --init-header --reg reg.test.dat --t2 --lta reg.test.lta This did result in a good registration, and we are hoping to incorporate this into our processing pipeline to ensure that we can use the FLAIR for refining the pill surface. The problem that we’ve run into is that we aren’t sure at which point this bbregister step occurs within the recon-all process flow. We were thinking there are a couple of possibilities: 1. manually create the transformation matrix for the FLAIR using the command mentioned above, and then re-run whichever steps necessary in recon-all to include this manually created xform; 2. apply the manually created xform to the mri/orig/FLAIRraw.mgz image to create a new, properly aligned mri/FLAIR.mgz, and then re-run recon-all with whatever steps/flags we need to include this FLAIR image to refine the pial surface. Unfortunately we're not exactly sure which flags to include in recon-all in order to most efficiently re-process our data with the manually created FLAIR transformation, and we were hoping you might offer some advice on this point. Please let me know if I can provide any additional information. [cid:32781EBE-87CB-4FF9-815F-4D732E675168@beckman.uiuc.edu][cid:45A8FE84-7BD3-4C2E-8618-AE9786828CF2@beckman.uiuc.edu]

International PhD Course in Molecular Medicine, Experimental Neurology Section, San Raffaele Hospital, Milan, Italy.
by Zonca Lucia 25 Aug '14

25 Aug '14

The Neuroimaging Research Unit, Vita-Salute San Raffaele University, Milan, Italy, headed by Prof. Massimo Filippi, is looking for graduate students interested in a three-year PhD program in the frame of the International PhD Course in Molecular Medicine, Experimental Neurology Section. Titles and Directors of Study of the programs are the following: 1. Network degeneration in motor neuron diseases (MND): a study of the structural and functional connectomes in amyotrophic lateral sclerosis and other MND. Prof. Massimo Filippi 2. Brain plasticity in multiple sclerosis. Prof. Massimo Filippi 3. Investigation of the functional and structural correlates of cognitive network function in pediatric MS patients. Dr Maria A. Rocca 4. Cervical cord atrophy as a tool for monitoring disease evolution and for predicting long-term disability in patients with multiple sclerosis. Dr Maria A. Rocca 5. The morphological, microstructural and functional MRI correlates of motor, cognitive and neurobehavioral impairment in patients with movement disorders. Dr. Federica Agosta 6. Multimodal magnetic resonance imaging diagnosis of frontotemporal lobar degeneration (ftld): using supervised machine learning techniques to classify individual FTLD and Alzheimer's disease patients. Dr. Federica Agosta The lab has a strong background in multiple aspects of neuroimaging from sequence programming and software design to the analysis of structural and functional images from patients with different disorders of the central nervous system. The candidate will join a group with multiple interests in the field in a positive and productive environment. The ideal candidate should have expertise in the acquisition and analysis of advanced MRI techniques (volumetric, diffusion tensor MRI and functional MRI). Expertise in voxel-based morphometry, tract-based spatial statistics, resting state and active fMRI analyses would be an advantage. She/he will have a good team-working attitude, be self-motivated and have a strong interest in pursuing research in a stimulating and competitive field of science. Admission requirements and procedures are described at http://www.unisr.it/view.asp?id=8802 Deadline for application submission is 11 September 2014.

anatorig vs anat in dlabel
by Kirstie Whitaker 25 Aug '14

25 Aug '14

Hi I have a very minor question about the naming scheme for tracula output. I have the folders anat and anatorig in the dlabel folder. Am I right that: anatorig is the T1 image in "freesurfer space" (256 x 256 x 256; LIA) anat is a rotated version of the T1 image in freesurfer space that lines up with the standard orientation used by FSL (256 x 256 x 256; LAS) So neither is actually in the same space as the *original* file that was passed to recon-all (176 x 240 x 256; LAS)? I ran mri_label2vol with dlabel/anat/anat_brain_mask.nii.gz as the --temp argument and the labels didn't line up nicely. They did line up with anatorig though. Is this what you'd expect?
