07 Mar '13

FYI ---------- Forwarded message ---------- Date: Thu, 7 Mar 2013 11:27:02 -0500 From: Dara Manoach <dara(a)nmr.mgh.harvard.edu> To: all(a)nmr.mgh.harvard.edu Subject: [All] post-doc position available Postdoctoral Fellowship at the Martinos Center for Biomedical Imaging and the Psychiatric Neuroimaging Division of the Psychiatry Department at Massachusetts General Hospital, Charlestown, MA Project: Multimodal neuroimaging studies of sleep and memory PI: Dara S. Manoach, Ph.D. The position will involve investigating the role of sleep in memory consolidation, how these processes go awry in schizophrenia and autism, and the efficacy of pharmacological and other interventions. Our work has linked a specific cognitive deficit in schizophrenia (the reduction of sleep-dependent memory consolidation) to a particular mechanism (sleep spindles) and we have preliminary evidence of an effective intervention. In collaboration with Dr. Robert Stickgold?s lab at Beth Israel Deaconess Medical Center, we are extending and expanding this basic and clinical research program using state-of-the art tools including high density EEG (polysomnography), MEG, functional connectivity MRI, fMRI, and behavioral studies. We are seeking someone to participate in these NIMH-funded investigations who is familiar with MEG/EEG methodology and data analysis, comfortable with methodological innovation, and an interested in optimizing and developing analysis streams tailored to the study aims and populations. New approaches and ideas are encouraged, as are independent projects that dovetail with current studies. The position requires working closely with the PI, as well as with Dr. Stickgold, other Martinos Center investigators, particularly Dr. Matti Hamalainen, Director of the MEG Core Lab, and lab mates to design studies, acquire data, and develop, explore, improve and apply data analytic techniques. Training in clinical research and in the acquisition, analysis, and interpretation of neuroimaging data will be provided. Requirements: PhD, Experience with MEG/EEG data analysis/methodology and/or other signal processing. Background in cognitive neuroscience, experimental psychology, and an interest in clinical applications are a plus. Position available immediately. Interested applicants should email: (a) CV, (b) statement of post-doctoral and career goals, (c) writing sample (e.g., a published manuscript), and (d) letters and/or contact information for three references to Dara Manoach at dara(a)nmr.mgh.harvard.edu. Stipend levels are in line with NIMH. A two-year commitment is required. Dara S.

optimizing output
by Linn Mittlestein 07 Mar '13

07 Mar '13

Dear list, I was wondering whether you have any suggestions on how to optimize accuracy of the Freesurfer output (both cortical and subcortical) in images aquired on lower scanning resolutions than 3 T (for examle 1 T)? Kind Regards, Linn

Re: [Freesurfer] Error

Hi Chikku-- What is your discrete variable? does it have more than one level? is it entered in the fsgd file? It looks like your discrete variable(s) is not defined properly. It must have at least two levels (e.g. Male/Female, RightHanded/LeftHanded, etc.). Check your fsgd file to so it is properly constructed: check the following link for formatting a legal fsgd file. http://surfer.nmr.mgh.harvard.edu/fswiki/FsgdFormat shantanu On Thu, March 7, 2013 7:40 am, Varghese Chikku wrote: > shantanu, > Many Thanks > Still error loading data, > this is what i am getting. > - freesurfer-Darwin-leopard-i686-stable-pub-v5.1.0 -------- > 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 > chikkus-MacBook-Pro:~ chikkuvarghese$ cat > /Users/chikkuvarghese/subject/qdec/anatomy.levels > right hippocampus > left hippocampuschikkus-MacBook-Pro:~ chikkuvarghese$ qdec > > Reading /Applications/freesurfer/tktools/tkUtils.tcl > > Using /Applications/freesurfer/lib/tcl/fsgdfPlot.tcl > > Loading data table /Users/chikkuvarghese/subject/qdec/qdec.table.dat... > Number of columns: 4 > fsid column: 1 > Number of factors: 3 > Number of subjects: 2 > Reading discrete factor levels from config file > /Users/chikkuvarghese/subject/qdec/age.levels > age > 70 > 71 > done. > Reading discrete factor levels from config file > /Users/chikkuvarghese/subject/qdec/anatomy.levels > right hippocampus > done. > ERROR: /Users/chikkuvarghese/subject/qdec/anatomy.levels is invalid.

Dear All I have a question about upcoming Freesurfer course registration (April 29 _ May 1). The registration link was supposed to be open and sent by today, but I still have not received it. I was wondering if you have any information and can help me. Thanks a lot Nooshin

Advice on integrating FSL's BET with recon-all
by Winter, Warren 06 Mar '13

06 Mar '13

Hi again, We have had some suboptimal results from FreeSurfer's skullstripping algorithm, even after iteratively trying different watershed thresholds and after checking the quality of Talairach registration. The results are pretty good, but often leave some dura matter and bits of neck behind whose higher intensity values, I believe, may end up skewing recon-all's later estimation of the range of intensity values within grey matter, and consequently compromising the accuracy of pial surface estimation. FSL's BET, however, seems to do a better job of extracting the brain, at least for our dataset. So, I was wondering if I might be able to skip over mri_watershed and feed autorecon2 and autorecon3 a brainmask.mgz file created using BET. I tried this procedure: 1) mri_convert <path/to/T1dcm> T1.nii.gz 2) bet T1.nii.gz BET_brainmask.nii.gz -A 3) mri_convert BET_brainmask.nii.gz BET_brainmask.mgz 4) recon-all -s <subjid> -autorecon1 -noskullstrip 5) mv BET_brainmask.nii.gz ./<subjid>/mri/brainmask.mgz 6) recon-all -s <subjid> -autorecon2 -autorecon3 And I got this error message, right after normalization2: " #@# Mask BFS Tue Mar 5 22:52:05 EST 2013 /net/rc-fs-nfs/ifs/data/Shares/DMC-Sheridan2/projects/FOCUS/FreeSurfer/2012_bet/mri mri_mask -T 5 brain.mgz brainmask.mgz brain.finalsurfs.mgz threshold mask volume at 5 ERROR: dimension mismatch between source and mask Linux rc-thunderball 3.2.21-mosix #1 SMP Mon Jul 2 08:55:48 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux recon-all -s 2012_bet exited with ERRORS at Tue Mar 5 22:52:06 EST 2013 " I'm guessing that the dimensions of norm.mgz and aseg.mgz didn't match those of brainmask.mgz, resulting during normalization2 in a mismatch between brain.mgz and brainmask.mgz. Does that seem right, and is there a possible workaround? Thank you!

Cannot see control points in tkmedit and freeview when connecting through X11
by Caspar M. Schwiedrzik 06 Mar '13

06 Mar '13

Dear Freesurfer Team, when I am trying to set control points in tkmedit (FS 5.1 or 4.5) or to see control points in Freeview (FS 5.1), I run into a strange problem when I connect to our server through X11. Namely, I cannot see the control points, although they are being set when I place them (they are saved in the respective .dat file). When I switch to a mosaic view, I can sometimes briefly see them, but as soon as I try to place new ones, the old ones disappear again. Any known workaround (apart from using VNC)? Thank you very much, Caspar

Hi all, I am running: preproc-sess -s sess01 -fsd bold -fwhm 5 -stc up -per-run However at the end it did not create an output like fmcsm. I only have fmc.nii, fmc.up.nii and fmcpr.up.nii. Am I doing something wrong, or these outputs are smoothed too? Thanks, Meryem

Hi Sean - This works on our redhat centos 4 and centos 6. I can dig around some more, but it'll have to wait for Monday b/c I'll be out of the office the next couple of days.

Question re: paradigm files for event-related design
by Cesar Echavarria 06 Mar '13

06 Mar '13

Hi freesurfers, I have an event-related design experiment which outputs a file with a line corresponding to every TR. i.e. for TR = 1 the first 3 columns of the file look like: 0 0 1 1 0 1 2 0 1 3 0 1 4 0 1 5 1 1 6 1 1 7 1 1 8 1 1 9 1 1 Assuming I have 5 seconds of fixation followed by seconds of condition 1. Is this the correct way to format this file? or should it have aline for every condition onset such as: 0 0 5 5 1 5 Perhaps, it makes no difference. Please let me know if you have insight into this Thanks, Cesar
