Re: [Freesurfer] mean thickness over hemisphere in stats file
by Bruce Fischl 12 Aug '13

12 Aug '13

Hi Ines sorry, this was my mistake. The command is "mris_anatomical_stats" NOT "mris_anatomical_thickness". If your SUBJECTS_DIR is set properly, you can run: mris_anatomical_stats -l $SUBJECTS_DIR/$subject/label/$hemi.cortex \ $subject $hemi where $hemi is lh or rh and $subject is the subject id you want to quantify cheers Bruce On Mon, 12 Aug 2013, Mürner-Lavanchy, Ines wrote: > ________________________________________ > From: Bruce Fischl [fischl(a)nmr.mgh.harvard.edu] > Sent: Friday, 9 August 2013 3:36 PM > To: Mürner-Lavanchy, Ines > Cc: freesurfer(a)nmr.mgh.harvard.edu > Subject: Re: [Freesurfer] mean thickness over hemisphere in stats file > > Hi Ines > > I think mris_anatomical_thickness is your best bet.

Optseq2 with Cygwin
by Lukito, Steve 12 Aug '13

12 Aug '13

Dear optseq2 developers, I would like to use optseq2 to develop optimal sequence for my MRI experiment. I have a windows machine (Windows 7, SP1, 64-bit OS) so I installed Cygwin-64 to run the optseq2. What I've done so far: - Downloaded optseq2.exe (Cygwin version) and put this into the Cygwin-64 folder - I run Cygwin and change my directory to Cygwin-64 where the optseq2 is - I followed instructions from previous email trails so I typed in chmod a+x optseq2 (to make optseq2 executable within the shell?) - Then I typed in ./optseq2 (since typing in optseq2 on its own results in -bash: optseq2: command not found) On both occasions (chmod... and ./optseq2), the command prompt returns without output. As I understand it, at least, for the second command I should get the help text for optseq? Have I done something wrong? Would really appreciate you help! Steve PS I am not familiar with UNIX so please be patient if my question is trivial :). Steve Lukito, MSc.

Re: [Freesurfer] trac-all inquiry
by Anastasia Yendiki 12 Aug '13

12 Aug '13

When you apply a rotation to the DWIs (as eddy_correct does), you need to apply the same rotation to the corresponding gradient vectors. See for example: Leemans, A., Jones, D. K., Jun 2009. The B-matrix must be rotated when correcting for subject motion in DTI data. Magn Reson Med 61 (6), 1336–49. If you don't want to pass the dicoms to trac-all directly, you can use mri_convert to convert from dicom to nifti.

Hi freesurfers, Is it possible to transform the statistical results of a surface analysis into an anatomical volumen? I've been reading about tkregister2 and mri_surf2vol, but I'm not confident. Any help would be appreciated Fernando Valle-Inclan

Alternately, the resource file for the shell can be configured to source the file automatically each time the shell is started. In the home directory of the user who will be running FreeSurfer binaries, edit the file .cshrc if C-shell will be used, the .tcshrc for enhanced C-shell, the .bashrc file for Bash, and .profile for sh, to include the previous two lines (which setenv FREESURFER_HOME, and then source the SetUpFreeSurfer.csh(or sh) script).

Qdec and one discrete variable
by ye tian 09 Aug '13

09 Aug '13

Dear freesurfers, I am experimenting qdec with one of my discrete variables. Besides qdec.table.dat file, I do have a .levels file with the two levels of the variable (say level1 and level2). However, I keep getting the following error message: Reading discrete factor levels from config file /$SUBJECTS_DIR/qdec/meditation.levels level1 done. ERROR: /$SUBJECTS_DIR/qdec/meditation.levels is invalid. Must have at least two levels. Error loading the data table. Is there something that I have missed in the declaration of the variable? Thank you very much! Sincerely, Ye

Dear Freesurfer expert, I have a simple question that I hope you can help me decide: we want to buy a Linux computer with reasonable 3D graphic card to run freesurfer. We are thinking of "NVIDIA Quadro K2000". Will that card give us problem when we run freesurfer from vnc? Thank you very much! Jim
