vtkMultiThreader error
by Don Hagler 08 Jun '09

08 Jun '09

When we run v430 on our cluster, running rocks redhat 4.3, we get the error message below when mris_volmask is run. From a google search, I see that someone had the same error message back in Oct 2007. Was a solution found for this? It runs fine on our desktop machines as well as when we log in directly to a node and run the job interactively. mris_volmask --label_left_white 2 --label_left_ribbon 3 --label_right_white 41 --label_right_ribbon 42 --save_ribbon --save_distance FREESURFERRECON_NTNU_PRE_095v2_20071126.173245.968000_1 SUBJECTS_DIR is /home/dhagler/data_test ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x1306ec80): Unable to create a thread. pthread_create() returned 12 Segmentation fault Linux compute-0-12.local 2.6.9-55.0.2.ELsmp #1 SMP Tue Jun 26 14:14:47 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux recon-all exited with ERRORS at Fri Jun 5 18:58:09 PDT 2009 _________________________________________________________________ Hotmail® has ever-growing storage!

Talairach coordinates
by Rafa x 08 Jun '09

08 Jun '09

Dear Freesurfer team, I used the lh.inflated file in an average subject to obtain its vertex’s coordinates. My question is: What anatomical space or reference system was use in this file? or instead, How I could obtain the Talairach coordinates of each vertex? Thank you in advance, Rafa.

about ROI
by Gabriel Go.Es. 08 Jun '09

08 Jun '09

hello freesurfers i have a doubt: i have convert a subject brainmask from freesurfer to nii and then i've convert a label that i create on freesurfer to *.nii using for registration the brainmask.mgz, i've made that for working in SPM, but when i open the ROI just not match with my subject...

extracting bval and bvecs from Siemens trio DWI
by raka maitra 08 Jun '09

08 Jun '09

Hello Doug The Siemen's Trio gives us Diffusion weighted images in the form of MR.10284.746.There are no extensions such as .dcm or .ima I can convert the dicom to nifti .nii format using SPM or FSL.But neither program extracts the bval or bvec information. I am working on Mac OsX 10.5 and am using FS v4.3.1 I tried using mri_convert subject/MR* dwi.nii -it siemens_dicom I am trying to ckeck the quality of the DWI and hence would like to perform eddy current correction and preprocess the images to generate FA maps. Thanks in advanceRaka

Disentangling age effects
by mmoayedi＠uhnres.utoronto.ca 08 Jun '09

08 Jun '09

Hi, I am studying two groups and have found that age is a confound (or is a covariate with an interaction between the two groups). Simply, when I correlate age between the two groups, there is an interaction (i.e., the slopes are different). My questions are: 1) is it appropriate to proceed with a map-wise t-test (with or without age as a nuisance covariate)? 2) is there a way to pull out age effects on each group specifically, i.e., use age as a covariate of interest? If neither of these methods is statistically sound, is there a method that can be used to describe age effects in each group, or characterize the findings? Thanks, Massih Moayedi

Color scale for the probability maps
by Eylem Kirlangic 08 Jun '09

08 Jun '09

Hi, When I plot the probability maps, the color scale bar takes negative values too (e.g., setting the threshold min 0 max 0.5, you get a scale bar between -0.5 and +0.5). How can I change the color scale bar so that it shows percentages? Thanks!

Temporal lobe segmentation
by Seyed Shahab Sharifi 08 Jun '09

08 Jun '09

Subject: Temporal lobe segmentation Date: Tue, 2 Jun 2009 17:40:21 +0100 Hi all, I am interested in automated segmentation of temporal lobe using freesurfer. I understand that it is possible to add up the individual regions of a specific lobe, create one massive label for that lobe, and get statistics on those. But I am not sure about the practicality of this approach for two reasons; first if all the regions of a temporal lobe can be labeled by Free Surfer, second because I am thinking that the most medial border of the superior temporal lobe could be my arbitrary cut off point of segmenting the temporal lobe, what anatomical/imaging feature has been defined for Free Surfer that distinguishes the white matter of the superior temporal lobe from the stem of temporal lobe (or say putamen) . I would appreciate it if one can guide me through this process if possible. cheers Shahab View your Twitter and Flickr updates from one place - Learn more! _________________________________________________________________ Share your photos with Windows Live Photos – Free. http://clk.atdmt.com/UKM/go/134665338/direct/01/

how to?
by Hoptman, Matthew 06 Jun '09

06 Jun '09

Hi all, How do I apply a Talairach registration to a segmentation? I can apply the transformation to the main volume and auxiliary volume in tkmedit, but I am not sure how to apply it to a segmentation volume. It looks like I can't load an aseg.mgz file as a main or auxiliary volume. --Matt Matthew J. Hoptman, PhD Research Scientist V Nathan S.

ROI analysis in average space
by adrzezga＠nmr.mgh.harvard.edu 05 Jun '09

05 Jun '09

Hi, my question is strongly related to Nr. 4 and 5 below (Alex Fornito). I am trying to run a surface-based ROI-analysis using one freesurfer-label on several subjects' imaging data which is already in standard space (fsaverage). These are resting state images from a SPM-based analysis which have been converted into surface-data. It seems that "mris_anatomical_stats" does not work on these average images, even when I try to use fsaverge as the corresponding space. I used: mris_anatomical_stats -l LABEL -t IMAGE -b -f DIRECTORY/LABEL.stats fsaverage lh Any advice would be appreciated !

Other stats will of course then be incorrect. You also have to be careful as the fsaverage surfaces contain less surface area (due to averaging) than individual subjects. There is a correction factor stored in the fsaverage surface files you can use if you want, I think mris_info will print it out. cheers Bruce On Fri, 5 Jun 2009, Alex Fornito wrote: > Hi, > I'm playing around with different ways of generating custom annotation files > using the fsaverage surface, and would like to estimate the surface area of > each ROI.

It seems like this should be possible with func2roi-sess (with the -anatlabel option) but it appears to need an analysis for some reason. I'm using continuous data, no event-related or block design paradigm, so I don't have an FS-FAST analysis. I just want the time series for a given ROI, so I don't see why I should need an analysis, but I can't figure out how to tell func2roi-sess not to use one. Perhaps I'm misunderstanding func2roi-sess or maybe there's a better function for me to use for this. What is the best way to extract the time series from a given ROI (e.g. rh.medialorbitofrontal) using FreeSurfer? Thanks,-- Alessandro D.
