Postdoctoral Position in Infant MRI Analysis at UNC-Chapel Hill
by gangli 17 Jun '16

17 Jun '16

Postdoctoral research associate positions are available in the Department of Radiology and Biomedical Research Imaging Center (BRIC) at the University of North Carolina at Chapel Hill (UNC-Chapel Hill). Our current focuses are to better understand the dynamic and critical early brain development in both health and disease, via multimodal neuroimaging analysis. The successful candidate will support our efforts either in advancing neuroimaging analysis technologies or in neuroscience applications. We are seeking highly motivated individuals who have extensive research experience in neuroimaging analysis (e.g., structural, diffusion or functional MRI) and demonstrated academic excellence, including publications in first-class journals and conferences. The candidate should have a Ph.D. (or equivalent) in Neuroscience, Computer Science, Applied Mathematics/Statistics, Electrical Engineering, Biomedical Engineering, or related fields. Good command of programming tools including Matlab, C++, Linux, and scripting are necessary to carry out the research work in this group. The successful candidate will be part of a diverse group including neuroscientists, radiologists, psychologists, physicists, biostatistician, and computer scientists, and will build upon the group's extensive foundation on neuroimaging analysis. If interested, please email resume to Dr. Gang Li (gang_li(a)med.unc.edu <https://outlook.unc.edu/owa/redir.aspx?SURL=r-ilRGXKGkv6jOyzGz3FjAPbDG9VNfM…> ).

Hi, Is there a way to get all coordinates (x,y,z) of the particular volume of interest (e.g., left-insula, left-thalamus)? Best, Aziz. -- Aziz Nanthaamornphong, Ph.D., Faculty of Technology and Environment Prince of Songkla University, Phuket Campus +66 7627 6716 (v) http://research.te.psu.ac.th/aziz

modifying files on older versions of FS
by Alexopoulos, Dimitrios 16 Jun '16

16 Jun '16

I have successfully processed data with FS v5.3 (linux/CentOS) using recon-all -all. Is it possible to make modifications to the 5.3-generated brainmask.mgz (primarily dura removal) and wm.mgz files using a much older 4.4 version of FS and then re-run recon-all on 5.3 with these modified files. I'd also be generating control points (control.dat file) on 4.4 as well. In other works are there file formatting differences between these FS versions for just these 3 files that could pose a problem when re-running the dataset.

Brodmann annotation on fsaverage
by Reza Rajimehr 16 Jun '16

16 Jun '16

Hi, Freesurfer has an annotation file for Brodmann areas, which is ?h.PALS_B12_Brodmann.annot. This Brodmann parcellation doesn't seem to be accurate in certain regions (e.g. in retrosplenial and perirhinal cortex). Does anyone have an alternative Brodmann atlas that can be visualized in Freesurfer (i.e. on fsaverage)? We are particularly interested in medial structures in occipital, parietal, and temporal lobe. Best, Reza

FSFAST- Cerebellum

Hi all, I am trying to extract mean time series BOLD data using FSFAST from Cortical ROIs + sub cortical ROIs and cerebellum. preproc-sess -s rest210 -fsd bold -surface fsaverage lhrh -mni305 -fwhm 6 -per-run -stc odd mri_segstats --annot fsaverage lh aparc --i rest210/bold/001/fmcpr.odd.sm6.fsaverage.lh.nii.gz --excludeid 1000 --excludeid 1004 --avgwf CorticalTimeSeries_lh.txt mri_segstats --annot fsaverage rh aparc --i rest210/bold/001/fmcpr.odd.sm6.fsaverage.rh.nii.gz --excludeid 2000 --excludeid 2004 --avgwf CorticalTimeSeries_rh.txt and for cortical time series mri_segstats --seg fsaverage/mri.2mm/aseg.mgz --ctab /opt/freesurfer/FreeSurferColorLUT.txt --id 10 --id 11 --id 12 --id 13 --id 17 --id 18 --id 26 --id 49 --id 50 --id 51 --id 52 --id 53 --id 54 --id 58 --i rest210/bold/001/fmcpr.odd.sm6.mni305.2mm.nii.gz --avgwf subCorticalTimeSeries.txt But I am not sure on how exactly to extract time series from cerebellar regions. So if I want to extract time series from regions as described in Buckner et.al 2011. Could I just use mri_segstats for the labels 601-628 in FreeSurferCololLUT.txt? If not could you please direct me to processes that I can use. Cheers, Sabin Khadka

Hippocampal subfields error
by Greenberg, Jonathan 16 Jun '16

16 Jun '16

Hi all I ran recon-all on data from about 60 participants pre and post an intervention, with the hippocampal subfields flag (e.g. "recon-all -all -subjid SPS01-1910_pre_lazar -hippocampal-subfields-T1"). The recon-all.log file states that the process finished without errors. However, the hippocampal-subfieldsT1.log indicated the following: "Error:Cannot find CTF archive /autofs/cluster/freesurfer/centos6_x86_64/dev/bin/segmentSubjectT1_autoEstimateAlveusML.ctf" (see below for the full content of hippocampal-subfieldsT1.log). I tried to run only the hippocampal subfield recon-all again (e.g. "recon-all -s recon-all -all -subjid SPS01-1910_pre_lazar hippocampal-subfields-T1") and received the same error message. I tried to look in the indicated folder ("/autofs/cluster/freesurfer/centos6_x86_64/dev/bin") and found a file named segmentSubjectT1_autoEstimateAlveusML (without the ctf extension). I do not know if this is the source of the problem. My FREESURFER_HOME directory is /autofs/cluster/freesurfer/centos6_x86_64/stable6/. My SUBJECTS_DIR is /autofs/cluster/lazar/Projects/jonathan-miracle/unpacking-dicoms/SUBJECTS_DIR/. Any suggestions? (full hippocampal-subfieldsT1.log below) Thank you!

Hi FreeSurfer users, I've been running dcmunpack and I get an error that said Found 0 unique series, even though it has dicom files. What does this mean and what could I do to fix the problem? Best, Talia
