TRACULA tract endpoints on cortical surface
by Barbara Kreilkamp 13 Aug '16

13 Aug '16

Dear Freesurfers and TRACULA experts, Thank you for your help so far. I am trying to map the endpoints of the tract probability distributions onto the cortical surface (as mentioned in Solsnes et al. 2016 NI and Storsve et al. 2016 PLos). I've somehow gathered that I need to do this (example one endpoint): flirt -ref /mri/orig/T1.nii.gz -in dpath/rh.ilf_AS_avg33_mni_bbr/endpt2.pd.nii.gz -applyxfm -init /dmri/xfms/diff2anat.bbr.mat I then loaded the images in Freeview and they look reasonable together with the lh.white and lh.pial surfaces: freeview -v /mri/brain -tv dapth/rh.ilf_AS_agv33_mni_bbr/endpt2_anat.pd.nii.gz What I don't get is how to do this: "we projected the tract endpoints onto the gray/white matter surface by sampling along the surface normal vector, anywhere within 6 mm (3 DWI-space voxels) of the gray/white junction and then smoothing along the surface with a 2D Gaussian kernel of 6mm full width at half max." (Solsnes et al. 2016) Any help would be greatly appreciated. Best wishes, Barbara

repost aseg.mgz error
by Jasmin Alves 12 Aug '16

12 Aug '16

Dear Freesurfer I encountered an error on the aseg mask for a participant, both hemispheres for the aseg appear on one hemisphere of the brain mask. I ran it a few times and I also used different T1s but it consistently showed this error. Is there a way I can correct this? Thanks, Jasmin -- Jasmin Alves Predoctoral Student Medical Biology Graduate Program University of Southern California jalves(a)usc.edu

Postdoctoral Position in pediatric imaging: Boston Children's Hospital/Harvard Medical School
by Gaab, Nadine 12 Aug '16

12 Aug '16

Postdoctoral Position at Boston/Children's Hospital & Harvard Medical School The GaabLab (gaablab.com)<gaablab.com> at the Laboratories of Cognitive Neuroscience in collaboration with the Fetal-Neonatal Neuroimaging and Developmental Science Center<https://urldefense.proofpoint.com/v2/url?u=https-3A__fnndsc.babymri.org_&d=…> at Boston Children's Hospital invites applications for a NICHD funded post-doctoral associate in the area of developmental cognitive neuroscience/pediatric (f)MRI. Available resources include a 3.0T MRI scanner, a child-friendly Mock scanner and analysis platforms based in MATLAB/UNIX. The candidate will be expected to oversee the analysis of pediatric and infant (f)MRI experiments, analyze behavioral and (f)MRI data, develop new analysis tools, prepare manuscripts for publication, and participate in conferences. The NICHD funded project aims to characterize trajectories of early structural, functional, and metabolic brain development in infants with and without a familial risk of developmental dyslexia, and intergenerational transmission of brain alterations associated with language-based learning disabilities will further be examined. The successful applicant should have a doctoral degree in a field related to developmental cognitive neuroscience (e.g., cognitive neuroscience, neuroscience, psychology, developmental psychology, medicine) or a background in electrical engineering, biomedical engineering or computer science. The successful applicant must possess excellent English verbal and written communication skills. Applicants are expected to have a very strong research background in the design and analysis of functional brain-imaging experiments. Experience with (f)MRI analyses programs (e.g., SPM, FSL, Freesurfer, AFNI) a must. Programming skills (MATLAB, C++; Python) are desirable and experience with MVPA or connectivity analyses a plus. Experience with the analysis of pediatric neuroimaging data sets and language and reading research are useful. Approximate start date is fall 2016 (the earlier the better). Successful applicants will be appointed at Children's Hospital Boston and Harvard Medical School. For consideration please send a statement of interest, a CV and a list of three potential referees via email to Nadine Gaab, PhD (nadine.gaab(a)childrens.harvard.edu<mailto:nadine.gaab@childrens.harvard.edu>). The search will continue until the position is filled. "If we knew what it was we were doing, it would not be called research, would it?" A.

Inter-rater and intra-rater reliability
by Annemarie Brandhofe 12 Aug '16

12 Aug '16

Dear FreeSurfer experts, I have a question regarding manual interventions during the recon-all script of FreeSurfer 5.3.0 (i.e. setting control points, performing white matter edits). How can we check for inter- and intra-rater reliability? In an earlier post you mentioned an intra- and inter-rater reliability study you did. Could you tell me the name of this publication? Thank you in advance for your help! Best regards, Anne

Performing GLM within a Mask Specified by Another GLM
by Timothy Hendrickson 11 Aug '16

11 Aug '16

Freesurfer Support, Here is what I would like to do: I have run a GLM on the entire cortex to determine whether there are significant differences in LGI between patients and controls. I then would like run a different GLM just with the clusters outputted from the previous GLM. It would seem that the best thing to do is to set a mask representing the clusters from the first GLM and then run the second GLM on the mask. Is this a reasonable thing to do? What steps/commands would I perform in order to do something like this? Respectfully, -Tim Hendrickson Timothy Hendrickson Department of Psychiatry University of Minnesota Mobile: 507-259-3434 (texts okay)
