normalization problem (versions 5.1 and 5.3)
by Maia Pujara 23 May '14

23 May '14

Hi all, After running 200+ subjects through recon-all using version 5.1, all but 30 came back with complete surfaces. The 30 that failed seem to have the same problem with normalization. After re-running these 30 subjects with v5.3, we were able to get a good quality brainmask.mgz output, which was not the case when we ran these subjects through v5.1. See attached for comparisons of v5.1 and v5.3 outputs. Would we need to be adding additional flags to get 5.1 to produce usable results for these subjects? Or might there be some other workaround for this? Thanks in advance! Maia

Create gifti surfaces from lh.white for MATLAB
by Bastian Cheng 23 May '14

23 May '14

Dear Freesurfer-Experts, I would like to create gifti-surfaces to use in matlab. That's what I am doing so far: mris_convert lh.white lh.white.gii I then try to open it using the "gifti" command (http://www.artefact.tk/software/matlab/gifti/) however, I get an error message from matlab: >>>>>>>>>>> ??? Attempt to reference field of non-structure array. Error in ==> gifti.subsref at 28 varargout{1} = this.data{j}.space.MatrixData; Error in ==> gifti.struct at 17 [values{i,:}] = subsref(this(:), substruct('.',names{i})); Error in ==> gifti.display at 17 eval([display_name ' = struct(this);']); >>>>>>>>>>>>>>> Am I missing something? Is there anything special with the .gii file form FS? Any help is appreciated! Bastian

Differing OS X version and recon-all
by Chiu, Bryan (PHTH) 22 May '14

22 May '14

Hi, Wanted to check in about Mac OS X and any effects on recon-all that I may not be aware of. A while back the Mac was updated to 10.9.2 from some other version of 10.x.x. I ran half of my recon-all on 10.x.x, and am running my 2nd half on 10.9.2. The update was due to some IT person thinking the older version had security flaws. Will I need to rerun all of my subjects on 10.9.2, or has there been no reported differences between these two versions? Thanks, - Bryan

mri_vol2vol memory error
by Ben Mooneyham 22 May '14

22 May '14

Hello all, I am doing pre-processing for resting-state fMRI volumes, but I have encountered an error and am unsure of how to correct it: I have previously determined the nonlinear warping transformations from my subjects' anatomical (T1) space to the 2mm MNI template using ANTs. At the end of my pre-processing pipeline, I am trying to transform my subjects' functional volumes (206 TRs of 2sec) into this MNI space by 1) transforming the functional volumes into subject T1 space using mri_vol2vol, and 2) applying the nonlinear warp (from ANTs) to the volumes in subject-T1 space to ultimately have my subjects' functional data in MNI space. However, I am getting an error while running mri_vol2vol, where it "cannot allocate region." I gather from looking around online that this is a memory issue, but I am not sure how to fix it. Thoughts? It is crucial that I be able to translate my functional data into common MNI space before performing second-level analyses... I do not encounter this issue when performing this transformation on functional connectivity maps (where I take an ROI defined in MNI space, transform it into T1, and then subject-EPI space, calculate the FC with the rest of the brain, and then invert the process by transforming back into T1, and finally MNI space). How can I get this to work with a larger file?

installation recon-all
by Ashley Rose 22 May '14

22 May '14

Hi Freesurfers, I've downloaded and installed Freesurfer on in VirtualBox running Ubuntu 12.04 (on a Windows 7 host machine). In my shell, though, it's installed with CentOS4 (see below) I've been working through the page on testing the installation. Everything works nicely, until I get to the recon-all commands. When I try having it just run the -autorecon1 stage on its own, I get this error: -------- freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 -------- Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME /usr/local/freesurfer FSFAST_HOME /usr/local/freesurfer/fsfast FSF_OUTPUT_FORMAT nii.gz SUBJECTS_DIR /usr/local/freesurfer/subjects MNI_DIR /usr/local/freesurfer/mni arose@HarryCallahan:/usr/local/freesurfer/subjects/buckner_data/tutorial_subjs$ recon-all -s bert -autorecon1 WARNING: tcsh v6.17.06 has an exit code bug!

Classifying thickness question
by pfotiad＠nmr.mgh.harvard.edu 22 May '14

22 May '14

Hi Bruce, I had a few questions concerning the mris_classify_thickness algorithm that you wrote: 1) Are there any other options (i.e. other flags) that can be specified in the mris_classify_thickness -o <output subject> [options] <hemi> <surf> <curv> <c1_subject1> <c1_subject2>... : <c2_subject1> <c2_subject2>... commandline? Because in the description of the command there is nothing reported under the "valid options are:" I believe I saw some other options reported in the code of the specific function, but I wasn't sure whether they could be used. 2) Are the two classes defined as two different groups of subjects such as male/female or healthy/disease? 3) I ran the command on 4 subjects (class1: 2 diseased subj, class2: 2 healthy subjs) and the result was 2 data files with 202 pairs of cortical thickness values each. However, I'm not really sure what those values represent. Are they vertex-wise thickness values that correlate somehow between <c1_subject1> <c1_subject2>, and <c2_subject1> <c2_subject2>, respectively, or are they clustered-wise thickness values? 4) Are there any other outputs besides those two data files that the command can come up with? Thanks in advance for all your help! Panos

Hi Ben, please post questions to the list and not to us personally. Thanks! I do not have an alternative. I think you are using Thomas Yeo's stream which we are not supporting. He just uses binaries from FS. doug On 05/22/2014 12:16 PM, Ben Mooneyham wrote: > Hi Douglas, > > Thank you for your response.

wm and ctx labels - mri_aparc2aseg
by Andrea Tateo 22 May '14

22 May '14

Hi FreeSurfer expert, after that I have used the command "recon-all" I would like to obtain wm-lh and wm-rh information ( for example wm-lh-bankssts,wm-lh-caudalanteriorcingulate,wm-lh-caudalmiddlefrontal, ...). I have read that mri_aparc2aseg command can help me, but when I use it I have two problems: 1) When I use the command mri_aparc2aseg --s subject I obtain as output the image "aparc+aseg.mgz" which contains information only about cortical label. 2) When I use the command mri_aparc2aseg --s subject --a.2005 I get the following message: ERROR: Option --a2005 unknown Can you help me? Moreover, the recon-all output in directory /mri is: aparc.a2009s+aseg.mgz, aparc+aseg.mgz, aseg.auto.mgz, aseg.auto_noCCseg.label_intensities.txt , aseg.auto_noCCseg.mgz aseg.mgz, brain.finalsurfs.mgz, brainmask.auto.mgz, brainmask.mgz, brain.mgz, ctrl_pts.mgz, filled.mgz, lh.ribbon.mgz, mri_nu_correct.mni.log, norm.mgz, nu.mgz, nu_noneck.mgz, orig, orig.mgz, rawavg.mgz, rh.ribbon.mgz, ribbon.mgz, segment.dat , T1.mgz, talairach.label_intensities.txt , talairach.log, talairach_with_skull.log, transforms, wm.asegedit.mgz, wm.mgz, wmparc.mgz , wm.seg.mgz Do you think that the searched information is here? Thanks for your help. Best regards, Andrea

missing temporal lobes
by Daly, Eileen 22 May '14

22 May '14

Hello all, We are having trouble with the output after running recon-all -all -subjid subjectx on our scans. Registrations and skull striping look okay, but the white matter and pial surface segmentations leave outportions of the anterior temporal lobe. After adding control points to the left temporal lobe, we then ran recon-all -autorecon2 -cp -autorecon3 -subjid subjects. This made the the left lobe look better, but then we spotted new missing bits on the right side anterior temporal lobe. Any ideas on dealing with these missing temporal lobe issues? Thanks, Eileen Daly

creating custom color table & annotation file
by Maria Jalbrzikowski 21 May '14

21 May '14

Dear Freesurfer experts, I would like to get your help. I extracted cortical thickness values from each vertex from each of my individual subjects (example: path/subject_id/surf/lh.thickness.fsaverage.mgh). I then ran a covariance analysis over the whole group and identified "modules" or groups of vertices that covary together. The modules are given the names of colors. I end up with a module (color) assigned to each vertex. I now want to visualize this data (so I can if these module reflect specific neuroanatomical structures), but I'm not sure about how to do this. Does anyone know how to do this? I tried to make a new color table, with my different module colors as the structures. I don't know how to then incorporate this information so that I can view it. I've read the tutorials on the label and annotation files, but I have only become more confused. If anyone can help me with this problem, I'd be very greatful! Thank you, Maria -- Maria Jalbrzikowski, Ph.D. Department of Psychiatry & Biobehavioral Sciences University of California, Los Angeles
