Freesurfer - problem with automatic labeling of V1 using the Hinds method in 5.1.0
by Andrew Bock 08 Mar '13

08 Mar '13

Hello, I am having a similar problem to one described on the freesurfer mail archive, where I receive the following error when trying to identify V1 using the Hinds method (i.e. recon-all -s <subject> -label_v1): processing subject V1_average... MRISreadVertexPosition(white): could not open file /usr/local/freesurfer/ subjects/V1_average/surf/rh.white No such file or directory MRISreadOriginalProperties: could not read surface file white No such file or directory could not read surface positions from white No such file or directory As Prof. Krish Singh indicated in July, it appears the problem occurs when trying to open rh.white (or lh.white) from the surf subdirectory in V1_average, which doesn't exist. I have run recon-all -s <subject> -make all, but it returns "make: Nothing to be done for `all'." Any help you can provide would be greatly appreciated!

entorhinal cortex volume question
by Cat Chong 29 Jan '13

29 Jan '13

Hello experts, I am very new to freesurfer so please excuse my basic question: We want to get measurements of entorhinal cortex volumes on a group of people. I found these results listed in ?h.aparc.stats. I also noticed another ?h.entorhinal_exvivo.stats, with different results. Which should I use for a group analysis of entorhinal volume and surface area, and why are the results very different? very best regards, catherine

selxavg3 error : NaN in Xtmp.mat file
by Sid Kundu 07 Dec '12

07 Dec '12

Hi Doug, I created a new first level analysis along with new contrasts and event numbers for a group of subjects I had previously done analyses on. All but one of the subjects finished selxavg3 without error, but one subject gave the following error: Saving X matrix to /home/sidkundu/freesurfer/sessions/Heading-TTP/LMV2010_N19_Heading-TTP/bold/TTP-analysis-3/Xtmp.mat Error using svd Input to SVD must not contain NaN or Inf. Error in cond (line 39) s = svd(A); Error in fast_selxavg3 (line 248) XCond = cond(XtX); >> ------------------------------------------ ERROR: fast_selxavg3() failed\n I looked at the generated Xtmp.mat file and it shows the design matrix X has all zeros in 2 columns, resulting in NaNs in the same columns for Xn, and corresponding NaNs in XtX. I'm wondering what would cause this or why it would only occur for only one subject. _________________________________ Sid Kundu Biomedical Engineering Boston University

flipping surface data
by kelsi 04 Dec '12

04 Dec '12

Hi Freesurfers, Is there a tool to flip the orientation of surface data to the opposite hemisphere? We are working with stroke patients, and I would like to do analysis of the contralesional hemisphere of all the patients. However, this requires putting them on the same hemisphere for ttests, etc. I saw an earlier thread online about a program for flipping in the works, I was just wondering if this is now possible? Thank you! Kelsi

Fw:contrast matrix
by Meng Li 13 Nov '12

13 Nov '12

Hi Freesurfer experts, I'm very sorry to bother you, but I am very confused with the following questions: My experimental design includes 3 discrete factors: diagnosis with two levels (A, B); genotype with two levels (G, T); gender (F, M), and two covariates. So I can get 8 classes: AGF, AGM, ATF,ATM, BGF, BGM, BTF, BTM. 1) I want to perform 2 (diagnosis)* 2(genotype) interaction analysis with regressing out the effect of gender and two covariates, but I don't know the rules for setting the contrasts for the interaction. The contrast matrix I used is: 0.25 0.25 -0.25 -0.25 -0.25 -0.25 0.25 0.25 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 is it correct? If it is correct, how to explain the results, for example, what does the positive (or negative) clusters stand for? Or the clusters showed in the t-test statistical map are the regions that have the significant interaction? 2) When I perform the main effect of dignosis, is the following matrix I used correct? 0.25 0.25 0.25 0.25 -0.25 -0.25 -0.25 -0.25 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (I think it regressed out the effect of genotype and gender, that is it takes the genotype as a covariable) Or I should create another fsgd file, that has 4 classes: AF, AM, BF, BM. And I can use the matrix (0.5 0.5 -0.5 -0.5 0 0 0 0 0 0 0 0) to perform the main effect of diagnosis. which one is right? Any help will be very appreciated. Best wishes, Meng Li

AAL labels

Has anyone created an AAL label file for Freesurfer? I've done some ROI analysis using AAL regions and want to display regional values on the freesurfer surface.

Freesurfer and FSL
by Ana Arruda 10 Oct '12

10 Oct '12

Dear experts, I'm an MSc student and part of my final project is related to the measurement of the volume of the hippocampus. The last thing I have to do is to compare two softwares, FSL and Freesurfer. On Freesurfer, I've used the following commands: recon-all -i where_my_subject_is -autorecon1 -s output_name then, related to the same subject recon-all -autorecon2 -s output_name After approximately 12 hours, and after comparing the results of Freesurfer and FSL, I found that those obtained with Freesurfer are bigger than those obtained with FSL. According to the literature the results are the reverse. Do you know any idea what I'm doing wrong? Thank you for your attention, Ana Arruda

Re: [Freesurfer] integrating FSL and Freesurfer
by noam Schneck 09 Oct '12

09 Oct '12

Hi Doug Here are more detailed versions of my first two questions. 1) I used tkmedit to look at the mean_func produced by a gfeat analysis of one subject's three functional runs overlayed onto the anatomical image produced by recon-all on that same subject(bert/mri/orig.mgz). The registration matrix I used was the anat2std.dat that was produced by running reg-feat2anat on all three of the feat analyses from the individual runs. When I did this I saw that the mean_func image was outside the boundaries of the anatomical image. Correspondingly, when I overlayed the zstat.nii.gz from the gfeat analysis onto the anatomical image I had activation outside of the anatomical image brain. 2) Originally, I ran BBR on a subject that I had run Recon-all for. I used BBR to register the example_func.nii.gz to the bert/mri/orig.mgz. I had BBR output an fsl.mat. I then used ApplyXFM in fsl to apply BBR's fsl.mat to register the example_func.nii.gz onto a T1 image that had been created by converting bert/mri/brainmask.mgz into niftii with mri_convert. I tried it again, this time converting the orig.mgz to niftii. In both cases the example_func in T1 space image produced by ApplyXFM is rotated about 90 degrees and also inverted. This is viewed in fslview, The corresponding T1 images created by mri_convert are not. What can I do to allow me to use BBR's fsl.mat within ApplyXFM?

More than two time-points in longitudinal base = Memory allocation error?
by Liz Bowman 03 Oct '12

03 Oct '12

Hello, I have several patients scans taken over multiple time points (up to nine time points in some patients). I thought I might be able to use these to create a base template for longitudinal processing, however the process fails and exits with errors if I try to create a base with more than two time points from a patient. This is a sample of the error log of the most recent attempt, with three timepoints: Resolution: 1 S( 128 128 128 ) T( 128 128 128 ) Iteration(f): 1 -- diff. to prev. transform: 0.876663 Iteration(f): 2 -- diff. to prev. transform: 0.0148738 Iteration(f): 3 -- diff. to prev. transform: 0.00156813 < 0.01 :-) Resolution: 0 S( 256 256 256 ) T( 256 256 256 ) Iteration(f): 1 -- diff. to prev. transform: 0.263086 Iteration(f): 2mri_robust_template(1035) malloc: *** mmap(size=262144) failed (error code=12)*** error: can't allocate region*** set a breakpoint in malloc_error_break to debugMRIalloc(256, 256, 256): could not allocate 262144 bytes for 68th slice Cannot allocate memoryDarwin 550D-UOM88670.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:32:41 PDT 2011; root:xnu-1504.15.3~1/RELEASE_X86_64 x86_64 recon-all -s KSx3 exited with ERRORS at Mon Jul 23 10:15:13 EST 2012 For more details, see the log file /Applications/freesurfer/subjects/KSx3/scripts/recon-all.logTo report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting I would be grateful for any advice.
