Dear Elizabeth, I would guess that something went seriously wrong in the recon-all with your data. Does Talairach registration and skull strip look reasonable? Antonin Skoch

Hello, I try to map the surface to the native space, using the following command adjusted for my data: mri_surf2surf --sval-xyz pial --reg register.native.dat rawavg.mgz --tval lh.pial.native --tval-xyz --hemi lh --s subjectname the output is: ERROR: --tval-xyz flag needs 1 argument FYI: --tval-xyz now requires a volume. So in the web-page ( http://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat) the comand is not correct. What kind of volume can I put, to get the surface in the native space? Thank, Silvia

SPC in surface area
by Maria A Infante 15 Aug '17

15 Aug '17

Hi everyone, I have a questions concerning the SPC values for an individual brain region. I am looking at group differences (3 groups) in SPC in surface and found one region that was significant after correcting for multiple comparisons. I want to follow up with pairwise comparisons. Is there a way to extract the SPC values for that particular region? Are these the same values as the ones on the stack file? Thanks, Alejandra

use manually defined talairach.xfm
by clemens.schroeder＠uzh.ch 15 Aug '17

15 Aug '17

Hi I got a Talairach Failure Detection Error and therefore did manual registration using tkregister2 following the advice at: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach_freeview Again following the advice on the site, I re-ran recon-all just to run into the identical error. When I checked talairach.xfm it was the same as BEFORE I did manual registration in tkregister2. The above site states: Because the talairach transformation affects everything in the stream it is necessary to rerun the whole process using your new talairach, which is a default. However, it seems this is not the default since recon-all comes up with its own talairach.xfm and overwrites my manual version, after which recon-all fails. How can I make recon-all use my manual registration?

recon-all error
by Yeseul Kim 14 Aug '17

14 Aug '17

Hi I'm beginner of freesurfer and have an error while using recon-all. I'm Mac (Sierra) user. My subject's data is under: /Applications/freesurfer/subjects/yeseul_data After open terminal, I put commands like: export FREESURFER_HOME=/Applications/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.sh export SUBJECTS_DIR=/Applications/freesurfer/subjects/yeseul_data/sbj1 recon-all –i $SUBJECTS_DIR/20170720_LHS.MR.HEAD_CNIR_IBS.0017.0001.2017. 07.20.16.26.07.667681.198987303.IMA –subject $SUBJECTS_DIR/sbj1_rec -all (My subjects' data is *.IMA format. Filenames are like "20170720_LHS.MR_HEAR_CNIR_IBS.0017.0001......198987303.IMA". I don't think I need to convert IMA format to another, right? Each subject has 192 IMA files and I want to apply recon-all to all of these files.) When I run these commands, I get a messages like: -------- freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c -------- Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME /Applications/freesurfer FSFAST_HOME /Applications/freesurfer/fsfast FSF_OUTPUT_FORMAT nii.gz SUBJECTS_DIR /Applications/freesurfer/subjects MNI_DIR /Applications/freesurfer/mni Yeseului-MacBook-Pro:~ yeseulkim$ Yeseului-MacBook-Pro:~ yeseulkim$ export SUBJECTS_DIR=/Applications/ freesurfer/subjects/yeseul_data/sbj1 Yeseului-MacBook-Pro:~ yeseulkim$ Yeseului-MacBook-Pro:~ yeseulkim$ recon-all –i $SUBJECTS_DIR/20170720_LHS.MR .HEAD_CNIR_IBS.0017.0001.2017.07.20.16.26.07.667681.198987303 –subject $SUBJECTS_DIR/sbj1_rec -all ERROR: Flag i unrecognized. i /Applications/freesurfer/subjects/yeseul_data/sbj1/ 20170720_LHS.MR.HEAD_CNIR_IBS.0017.0001.2017.07.20.16.26.07.667681.198987303 subject /Applications/freesurfer/subjects/yeseul_data/sbj1/sbj1_rec -all Darwin Yeseului-MacBook-Pro.local 16.7.0 Darwin Kernel Version 16.7.0: Thu Jun 15 17:36:27 PDT 2017; root:xnu-3789.70.16~2/RELEASE_X86_64 x86_64 recon-all -s exited with ERRORS at Tue Aug 15 01:08:53 KST 2017 For more details, see the log file To report a problem, see http://surfer.nmr.mgh.harvard. edu/fswiki/BugReporting Does it matter with the format of my data files?

mri_binarize/mri_mask command help
by Yagmur Ozdemir 19 14 Aug '17

14 Aug '17

Dear FreeSurfer experts, I am trying to use the following command to merge the volume file of a template with original T1 orientation*, with a file like rawavg to get the full brain volume, but the following attached image gets produced and I am pretty sure, as a freesurfer novice, I am using a wrong command line. I have tried mri_mask as well but do not think it is the command to go. I also checked if two volumes are in the same orientation using mri_orient. mri_binarize --i rawavg.mgz --o scanner.template_angle.mgz --wm+vcsf * (I have the native oriented version of this volume template as well, and I attached a photo of the template as well) I would deeply appreciate if someone could help me correct my command line. Thank you all for the time and help Idil

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. For further information about this appointment, please contact Dr. Emma Jane Rose at emmajanerose(a)psu.edu or 814-865-0114.
