Two problems
by Juergen Haenggi 20 Mar '07

20 Mar '07

Dear Freesurfer users I have two problems: I upgraded Freesurfer (from Linux CentOS4 v3.0.3 to v3.0.5) and recognized that the "foreach" command do not work any longer. The following error occured: ERROR: Flag -Patient03_2001 unrecognized. -Patient03_2001 -all ERROR: Flag -Patient03_2002 unrecognized. -Patient03_2002 -all The other problem concerns the selection of the tcsh shell on Mac OS X. I can change from a bash to a tcsh shell. Thanks for help in advance Best regards Juergen --------------------------------------------------------------------------- Juergen Haenggi, Ph.D. student Department of Neuropsychology Institute of Psychology University of Zurich Binzmuehlestrasse 14, PO Box 25 8050 Zurich, Switzerland 0041 44 635 73 97 (phone office) 0041 76 445 86 84 (phone mobile) 0041 44 635 74 09 (fax office) BIN 4.D.04 (office room number) j.haenggi(a)psychologie.uzh.ch (email) http://www.psychologie.uzh.ch/neuropsy/ (website) http://www.juergenhaenggi.ch (private website) ---------------------------------------------------------------------------

RE: [Freesurfer] RE: Version compatability
by Fornito, Alexander 19 Mar '07

19 Mar '07

Hi Nick, One thing I couldn't work out from the example image associated with the release notes is whether the different areas are located in the non-cortical regions of the midline. If they include cortical regions (and it appears that subgenual portions of the cingulate are) then I am interested in these areas.

Legacy flag
by Fornito, Alexander 19 Mar '07

19 Mar '07

Hi, I was just seeking some clarification re: the legacy flag in recon-all. Can I use it on subjects procssed with older versions of Freesurfer to reconstruct surfaces that will be consistent with those generated with older versions (i.e., I can collapse data from the two versions), or is the legacy flag intended to allow new versions of recon-all to be used on old data, effectively 'updating' the surfaces (meaning they should not be analyzed together with data generated using older versions). Thanks, Alex Alex Fornito JN Peters Research Fellow Melbourne Neuropsychiatry Centre and Department of Psychology National Neuroscience Facility The University of Melbourne Levels 2 & 3, Alan Gilbert Building 161 Barry St Carlton South Vic 3053 Australia Ph: +61 3 8344 1861 Fax: +61 3 9348 0469 email: alexander.fornito(a)wh.org.au

getting info from recon-all.log
by Sameer Walawalkar 16 Mar '07

16 Mar '07

Hello, My recon-all command (actually two of them) ran for some 30 hrs and 12 hours (the second one with nohup) before my windows macine rebooted. I wanted to see what was the status of the imlementation and so decided to look into the Status and Log Files. Both recon-all.log and recon-all-status.log files have the same entry given below. MNE software location set to /mnt/data/home/sameer/Software/MEGswdir/mne MATLAB software location set to /mnt/data/home/sameer/Software/MEGswdir/matl ab /mnt/data/home/sameer/Software/MEGswdir/mne/bin/mne already in PATH Note : Remember to set SUBJECTS_DIR and SUBJECT environment variables correctly. Note : FreeSurfer environment is needed to run mne_setup_source_space This really doesn't tell me anything. Can someone please shed some light on this? thanks, sameer

Announcement: open access MR data (OASIS)
by Daniel Marcus 15 Mar '07

15 Mar '07

Dear Colleagues, The Open Access Series of Imaging Studies (OASIS) is now available at www.oasis-brains.org <http://www.oasis-brains.org/> . The data are publicly available under to a liberal Data Use Agreement available here: http://www.oasis-brains.org/app/template/UsageAgreement.vm. The first data set includes structural MR obtained from 416 subjects aged 18 to 96, including 100 subjects diagnosed with very mild to moderate Alzheimer's Disease. A longitudinal data set will be released in the coming months. A manuscript describing the project is currently in press at Journal of Cognitive Neuroscience. For more information, please visit the website. Of particular interest to this group, Bruce Fischl's group is kindly churning the whole data set through Freesurfer. The resulting goodies will be made freely available as open access data. Make sure to thank Bruce and Jenni next time you see them.

importing cartesian coordinates file
by abel cruz vadell 14 Mar '07

14 Mar '07

Hi everyone Could I import in FreeSurfer (specifically in TKSurfer) a cartesian coordinates files? I need to locate the position of my EEG electrodes (previously translated to the brain and each one containing the information of one hemisphere) into the surfaces generated in FreeSurfer (orig and inflated). Is there any registration tool in FreeSurfer to do that? Or any other way? Thanks ______________________________________________ LLama Gratis a cualquier PC del Mundo.

mri_convert and recon-all
by Sameer Walawalkar 14 Mar '07

14 Mar '07

Hello, I have two questions. 1> I am following instructions from http://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer-Linux-platform-releas… Under GETTING STARTED WITH YOUR OWN DATA there are two directives: cp -r <path_to_dicoms>/95555-2-*.dcm 001/ cp -r <path_to_dicoms>/95555-3-*.dcm 002/ with special note: . Note that in your own case, the name of the dicom files will be different (in this example, 95555-2-*.dcm consisted of 128 files). My MRI data is essentially a directory (directory name is a many digit number like 123456789) with four subdirectories named 1, 2, 3 and 4. So I have used the following commands cp -r <path_to_dicoms>/12345..../1/*.dcm 001/ cp -r <path_to_dicoms>/12345.../2/.dcm 002/ This is because directories 2 and 3 have 256 slices whereas 1 and 4 had six slices. (this could change from subject to subject) After that I do mri_convert -it dicom -ot mgz 001/ 001.mgz mri_convert -it dicom -ot mgz 002/ 002.mgz Is this correct procedure? This does create the .mgz files. 2> After this, I gave the command recon-all -autorecon-all -subjid <subjid> and this has been running for many hours now (as warned on the website). It has already created slices and sets. My understanding is it will do just about everything INCLUDING triangulation which is used for BEM forward moderls using MNE. Is this correct? Thanks for your help. best, sameer
