visualize fsaverage
by Thục Trinh 20 Jan '16

20 Jan '16

Hello freesurfer experts, I'm having a trouble with visualize the first level analysis output of FSFAST on brain surface (fsaverage). When I open tksurfer tool to look at the contrast for the analysis on Right hemisphere space, the result display the contrast on left hemisphere and vice versa when I want to display the contrast on Left hemisphere space. I already checked the registration quality after run pre-processing and the results were quite good. I hope you can help me to figure out this problem. Thank you and have a nice day, Trinh

Longitudinal analysis with single timepoint scans
by Bronwyn Overs 19 Jan '16

19 Jan '16

Hi Freesurfer Mailing List, We are running a longitudinal analysis (in R) using 2 time points with scans that have been through the Freesurfer longitudinal pipeline. We were also hoping to incorporate individuals with only a single scan into our analysis. Does it make sense to use long images (2 timepoints) with cross images (1 timepoint) in the same analysis, or can they not be used together because the cross sectional images have not undergone the same processing steps? -- Kind regards, Bronwyn Overs Research Assistant Neuroscience Research Australia Neuroscience Research Australia Margarete Ainsworth Building Barker Street Randwick Sydney NSW 2031 Australia *M* 0411 308 769 *T* +61 2 9399 1883 neura.edu.au <http://neura.edu.au> Follow @neuraustralia on twitter <https://twitter.com/neuraustralia>Follow NeuRA on facebook <https://www.facebook.com/NeuroscienceResearchAustralia>Subscribe to the NeuRA Magazine <http://www.neura.edu.au/help-research/subscribe>

How to determine Freesurfer version used for trac-all
by Alicia Thomas 19 Jan '16

19 Jan '16

I’d like to determine which version of Freesurfer was used to recon-all and trac-all for a subject. Half of my subjects were run using version 5.1 and the other half using version 5.3. I want to determine which version was used for which subjects. Thanks for the help! Alicia

(no subject)
by EJ Nikelski 19 Jan '16

19 Jan '16

Hi all, I'm testing Freesurfer 5.3 and have a question about processing 1.5T versus 3.0T scans. Specifically, is there a switch in recon-all? I've observed some using a "-3T" switch, but I can't see this option documented in the "recon-all -help" output. I've executed test runs on a VM both with and without this option ... which seems to produce different results in the ROI quantification stats, although no change in the nu_correct arguments (I would have expected a different -distance value, but always appears to be set to 50). So, in sum, is there as 1.5T/3.0T switch in recon-all, and what does it do? Thanks, -jim -- ================================= Jim Nikelski, Ph.D. Bloomfield Centre for Research in Aging Lady Davis Institute for Medical Research Sir Mortimer B.

glmfit flag --frame-mask
by Victor Montal Blancafort 19 Jan '16

19 Jan '16

Dear FS Experts, I have seen few posts about this mri_glmfit flag, and I would like to know how it works. In an older post, ( https://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg32412.html) Doug suggested to use this flag when only some subjects should be exclude for each vertex (i, e. differnet number of subjects to exclude per vertex). Could anyone give me an insight on how this works? My intention is to perform a GLM analysis of some DTI metric volumes projected into the surface. However, some of the DWI volumes are cutted, so I would like exclude those vertexs where there is no signal (i,e value 0). Will --frame-mask work for this? Any other suggestion? Any help will be very appreciated! Thank you in advance, Victor Montal

Little cluster after FDR correction
by stdp82＠virgilio.it 19 Jan '16

19 Jan '16

Hi list, I have performed a seed-based fcMRI analysis by FAST.After mri_glmfit, I have obtained a sig.nii.gz which contains uncorrected results.I have corrected by FDR using the graphical interface provided in tksurfur. The FDR corrected contains some very small areas (<5-10 voxels) which I would like to hide in order to present a more clear map. How is possible to do it?I have tried with mri_surfcluster. To have vwsig.nii.gz I should have a CSD file. But this file could be also produced when FDR correction is applied? I'm very confused.Please, could you help me because from several days I'm trying to have a solution.Thank you very much for your work.Kind regards. Stefano

Using freesurfer on a partial brain
by Kevin Aquino 19 Jan '16

19 Jan '16

Dear Freesurfer list, I was wondering if anyone here has used freesurfer on anatomical scans acquired on a partial brain? I realise that recon-all and many of the tools are suited for a full brain, but I was wondering if anyone out there has had experience making the tools work for this scenario? Not necessarily the parcellations and the full set-up, but other tools such as segmentation, creating a white and pial surface and topology fixes.

postoc opportunity in Melbourne, Australia
by Sarah Whittle 19 Jan '16

19 Jan '16

Postdoctoral Research Fellow Position at The University of Melbourne Melbourne Neuropsychiatry Centre, Department of Psychiatry A/Prof Sarah Whittle and Dr. Julian Simmons seek a postdoctoral research fellow to work on a number of longitudinal studies that aim to characterise neurodevelopmental risk/resilience for mental health problems in children and adolescents. A full or part-time position is available; FTE is flexible to accommodate the most suitable applicant. This position is for one year (or longer if part-time), with the possibility of an extension depending on grant funding. Start date is asap. We are looking for a postdoctoral scientist with strong quantitative skills. The successful candidate will primarily be responsible for conducting data analysis for both cross-sectional and longitudinal data spanning a broad range of modalities (e.g., behavioural, neuroimaging, neuroendocrine); assisting the Investigators with data analyses; supervising postgraduate students; and writing scientific papers and presentations. Additional opportunities to work on other ongoing studies are also available. Position qualifications include a PhD in developmental or quantitative psychology, neuroscience, mathematics, or statistics (note that individuals close to completion of their PhD, or appropriately qualified individuals without a PhD may be considered); strong statistical skills and experience with statistical analysis packages (particularly SPSS, Stata, R, and/or MPlus); ability to work independently and in a team environment on multiple tasks and projects and to share expertise through training others. Desired (not required) skills include: Experience with longitudinal statistical analysis; experience with specialized software programs for neuroimaging analysis (FSL, MATLAB, SPM, FreeSurfer); experience with fMRI analysis; experience with neuroendocrine assaying and analysis; experience with structural equation modelling. Excellent scientific writing skills are also desired. Please send a letter of research interests, a CV, and contact information for three references to Sarah Whittle (swhittle(a)unimelb.edu.au<mailto:swhittle@unimelb.edu.au>) and Julian Simmons (jgs(a)unimelb.edu.au<mailto:jgs@unimelb.edu.au>).
