Error Talairach registration
by Rajagopalan, Venkateswaran 16 Aug '12

16 Aug '12

Hi All, When I ran recon-all -autorecon1 in one of my subject I encountered the following error ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050) Manual Talairach alignment may be necessary, or include the -notal-check flag to skip this test, making sure the -notal-check flag follows -all or -autorecon1 in the command string. so I ran the command as follows recon-all -notal-check -autorecon1 -subjid nonhyper_44 still I encounter the above error I don't know what I am doing wrong here.

TRACULA -prep error
by Richard Binney 16 Aug '12

16 Aug '12

Hi Anastasia et al., I previously had TRACULA running wonderfully on a test dataset. I was tasked with writing an in-house step-by-step manual for dummies. Since then, a colleague has followed my manual with a new dataset and had problems. After trying to determine whether it was her install or something about her data and failing to find anything, I returned to re-run the subject I had already successfully processed. Nothing has changed in my install (TRAC-all version etc) ODDLY, this re-run is suffering from the same problem as my colleague. We ran trac-all -prep -dmrirc and it exited without any errors. However, there seem to be some files missing from the output: control.dat data.nii.gz nodif_brain_mask.nii.gz Bedpostx will not run due to the *data* file being missing and I'm sure the other missing files will cause problems. What is going on? I knew to look for these files as at some point I found the following list for the \dmri\. I can not re-find a post with this list so I'm sorry if it related to a solution to our current problem. Please help Richard brain_anat_mni.nii.gz dtifit_L2.nii.gz dwi_orig_flip.nii.gz brain_anat.nii.gz dtifit_L3.nii.gz dwi_orig.mghdti.bvals brain_anat_orig.nii.gz dtifit_MD.nii.gz dwi_orig.mghdti.bvecs bvals dtifit_MO.nii.gz dwi_orig.nii.gz bvecs dtifit_S0.nii.gz dwi_snr.txt bvecs.norot dtifit_V1.nii.gz lowb_brain.nii.gz control.dat dtifit_V2.nii.gz lowb.nii.gz data.nii.gz dtifit_V3.nii.gz mni dtifit_FA.nii.gz dwi.ecclog nodif_brain_mask.nii.gz dtifit_L1.nii.gz dwi.nii.gz xfms

Re: [Freesurfer] Whole brain vertex values?
by Douglas N Greve 15 Aug '12

Hi Molly, you can use the y.mgh file that is created by qdec. This is a stack of all of your subjects in the standard surface space. You can convert to nifti if that is more convenient. BTW, the stats table just gives you the stats for each ROI. If this is something you want, then use aparcstats2table and/or asegstats2table. doug On 08/15/2012 04:55 PM, Molly DuBray wrote: > thanks for the prompt reply- > > i'd like to export raw thickness values for each vertex for a number of subjects. > (i.e. as if the parcellation were 200,000 rois) > > in order to concatenate this for all subjects, i envisioned using qdec's 'generate stats table' function. > > my understanding is that freesurfer does not store an image file of thickness values, but instead computes these on the fly within qdec... > > the main reason we are trying to do this is because i am trying to run longitudinal study with multiple timepoints, and am having all kinds of trouble. i decided to run the stats models in another package (outside of qdec) with the hope of reimporting the analyzed data. > > thanks again. > ________________________________________ > 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, August 15, 2012 2:41 PM > To: freesurfer(a)nmr.mgh.harvard.edu > Subject: Re: [Freesurfer] Whole brain vertex values? > > Hi Molly, I don't understand what you are asking.

Whole brain vertex values?

Hello, Is there a way to export cortical thickness values for each vertex across the entire cortex? Can this be done using Qdec to generate a larger stats table for a group of participants?

Converting data from fsaverage to SPM
by Eduardo Europa 15 Aug '12

15 Aug '12

Hello, I have two questions: First: I made left hemisphere anatomical ROIs using the freesurfer cortical parcellation atlas and fsaverage's data. However, when I convert these ROIs from .mgz to an SPM-compatible format (.img), the LH ROIs show up on the right. Any idea on how to resolve this problem? The ROIs I need are customized (i.e., I needed to merge some of the areas, and did so via relabeling), but for simpler purposes let's just say I used lh.BA44.label for now. Here are the commands I used: cd $FREESURFER_HOME/subjects/fsaverage mri_label2vol --label label/lh.BA44.label --temp mri/T1.mgz --identity --o lh.BA44.mgz mri_convert lh.BA44.mgz lh.BA44.img Second: I would like to normalize these anatomical ROIs to MNI space in SPM. To do this I was thinking about taking fsaverage's anatomical file, converting it to an SPM-compatible format, estimate the normalization parameters from fsaverage's anatomical to SPM's T1 template, and then writing those parameters to the anatomical ROIs. Therefore am I correct in converting fsaverage's T1.mgz to .img since I am specifying that as the template in the mri_label2vol above?

T-value intensity overlayed onto 2009 Destrieux Parcellations
by David Vazquez 15 Aug '12

15 Aug '12

Hi, We would like to visually display some t-values onto a brain using the 2009 Destrieux freesurfer parcellations. We have our own t-values for each parcellation. We would like to display a color-coded spm map for all parcellations, and would like each parcellation to represent the same intensity, instead of voxel by voxel, as was done by Watkins et al. (2001). Has anyone done this? Or have a clue where to find the relevant options? Thank you, David Vazquez Watkins, K.E., Paus, T., Lerch, J.P., Zijdenbos, A., Collins, D.L., Neelin, P., Taylor, J., Worsley., K.J., and Evans, A.C. (2001).

Re: [Freesurfer] sulcal depth/cortical folding
by Douglas N Greve 14 Aug '12

14 Aug '12

Hi Hugh, you can run mris_anatomical_stats passing it the sulc file as input. This will give you averages within aparc. I'm not sure what you mean by "measuring cortical folding". What measure would you accept? There's the sulcal depth and then there's curvature (?h.curv). There are two types of "normalization". One is intensity normalization which is a preprocessing step before the segmentation. "Normalization" is also refers to intersubject registration. Probably you mean the latter. doug On 08/13/2012 09:56 PM, Hugh Pemberton wrote: > Hi Doug, > > Thanks so much for getting back to my original question (have included > below) and apologies if my question seems trivial but I'm a bit of a > novice with freesurfer..
