FreeSurfer MRI segmentation
by Maheen Siddiqui 11 Feb '16

11 Feb '16

Dear FreeSurfer Users, I have a T1 weighted MRI scan and have run the recon-all command on it. For my steps moving forward I need to have 4 layers of tissue i.e. 4 segmentation files - GM, WM, CSF and extra cerebral tissue. Which of the outputs from recon-all will give me the segmentation? I thought at first that brain.mgz was what I needed but having viewed brain.mgz in Freeview, it is just the skull stripped version of the T1 scan. Is there any document that details all the outputs of recon-all? Many thanks for any advice I can get! Maheen

Processing of young children using Freesurfer
by Zoellner, Frank 11 Feb '16

11 Feb '16

Hi, I am currently working on a project involving brain morphometry of 2 year old children. We are interested in segmenting the ventricle and I tried to run freesurfer using the standard recon-all -all for a first test. Unfortunately, freesurfer reports an error (see attached log file). I also read about that it is advised to run freesurfer with patient age >5 but maybe someone has an idea how to solve this. As far as I get from the step it crashes at the intensity correction step? Do I need to calculate some sort of template maybe ?

difference in 001.mgz found
by Krieger, Donald N. 10 Feb '16

10 Feb '16

These runs were executed on the Open Science Grid. So the data file, the scan, was uploaded to grid worker machine, placed in a transitory directory, and processed. The full pathname of the file is included in 001.mgz. I got it by: zcat mri/orig/001.mgz | strings Here are the input and output file names for 2 of the runs: /var/lib/condor/execute/dir_31034/MRN_1_defaced.mgz /scratch/tmp.FFTGBhmgp8/MRN_1/mri/orig/001.mgz /var/lib/condor/execute/dir_3734674/glide_HRFaAm/execute/dir_3741395/MRN_1_defaced.mgz /scratch/tmp.ghJfB4leGR/MRN_1/mri/orig/001.mgz Best - Don > -----Original Message----- > From: freesurfer-bounces(a)nmr.mgh.harvard.edu [mailto:freesurfer- > bounces(a)nmr.mgh.harvard.edu] On Behalf Of Krieger, Donald N. > Sent: Wednesday, February 10, 2016 6:38 PM > To: Freesurfer support list > Subject: Re: [Freesurfer] comparing multiple runs on the same scan > > It looks like they do give the same results. > I have to write something to go through everything systematically which I may > not get to till tomorrow. > Also I am checking to see whether there was some difference in how 001.mgz > was created. > The source image file on which we are running freesurfer is a defaced.mgz . > It's possible that it was sitting in a different directory for the different runs > since the runs were executed by a work flow management system (Pegasus) on > the Open Science Grid. > > Don > > ________________________________________ > From: freesurfer-bounces(a)nmr.mgh.harvard.edu [freesurfer- > bounces(a)nmr.mgh.harvard.edu] on behalf of Douglas N Greve > [greve(a)nmr.mgh.harvard.edu] > Sent: Wednesday, February 10, 2016 6:13 PM > To: freesurfer(a)nmr.mgh.harvard.edu > Subject: Re: [Freesurfer] comparing multiple runs on the same scan > > That probably means that there is something in the header that is different.

comparing multiple runs on the same scan
by Krieger, Donald N. 10 Feb '16

10 Feb '16

We would like to confirm that we are getting identical results from multiple freesurfer runs on the same data set. To do so we are comparing identically named files using md5sum and would very much appreciate your thoughts on our results. For multiple files, we concatenate them and pipe the output into md5sum. Below is a table showing what we've found so far. I take hope from the positive matches we get from all of the .annot files and from the fact that 001.mgz does not match. This latter suggests that there is a date or something embedded in some of the files from separate runs which defeats the match. Please let us know what you know about this and thanks. file(s) md5sum result label/*.annot match label/*.label match mri/wmparc.mgz mismatch surf/qsphere.nofix surf/rh.sphere mismatch mri/orig/001.mgz mismatch mri/transforms/talairach.m3z match mri/transforms/talairach.m3z.inv.x.mgz mri/transforms/talairach.m3z.inv.y.mgz mri/transforms/talairach.m3z.inv.z.mgz mismatch mismatch mismatch Best - Don Don Krieger, Ph.D. Department of Neurological Surgery University of Pittsburgh

Dear. Freesurfer team. Hi. I'm using freesurfer 4.5 version. While doing the motion correction, an error occurred. the command I used: mc-sess -s $SUBJECT -df sessdirfile -fsd bold_retino -targrun $DATA_DIR/$SUBJECT/bold_decode/003 the error I have: /home/jbang/Projects/replay/epi/replay01/bold_retino 3dvolreg -verbose -dfile 025/fmc.mcdat -base 025/tmp.mc-afni2.32291/tempvol.nii.gz -prefix 025/tmp.mc-afni2.32291/outvol.nii.gz 025/tmp.mc-afni2.32291/invol.nii.gz ++ 3dvolreg: AFNI version=AFNI_2008_07_18_1710 (Feb 10 2009) [64-bit] ++ Authored by: RW Cox *+ WARNING: If you are performing spatial transformations on an oblique dset, such as 025/tmp.mc-afni2.32291/tempvol.nii.gz, or viewing/combining it with volumes of differing obliquity, you should consider running: 3dWarp -deoblique on this and other oblique datasets in the same session.

FS 5.3 and OS X 10.11
by prasser 10 Feb '16

10 Feb '16

Hi, On the download page it mentions that Freesurfer v5.3 is not compatible with OS X 10.11 because of an implementation of SIP. As a test, I have run a few subjects with v5.3 under OS X 10.11.3 with SIP enabled but was unable to see any problems, with all test subjects completing without error. I was wondering what I should be looking for (i.e. in the .log etc?) that would indicate that v5.3 is not compatible with OS X 10.11.3. Thanks.

Free surfer- correcting for head size
by Christina van den Brink 10 Feb '16

10 Feb '16

Hello, I have a question regarding volume-correction for the morphometry stats obtained via recon-all. I’ve noted that eTIV is derived using the atlas scaling factor in order to account for head size. I’m wondering whether the other volumes given, e.g. TotalGray or lhCorticalWhiteMatter, have also been corrected for head size? If not, is there a recommended method in which to do so so that regional volumes can be compared between participants? Many thanks for your help! Best, Christina
