FS 5.1 MNI305 aparc+aseg registration with FSL MNI152
by raij＠nmr.mgh.harvard.edu 13 Mar '13

13 Mar '13

Dear fellow Surfers, I am trying to overlay FreeSurfer 5.1 MNI305 (=fsaverage) aparc+aseg.mgz 3D volumes (caudate, putamen, pallidum, etc) onto FSL MNI152 2mm resolution volume. I first extract the nuclei from MNI305 aparc+aseg.mgz, for example: mri_extract_label $FREESURFER_HOME/subjects/fsaverage/mri/aparc+aseg.mgz 11 MNI305_3D_masks/mask_lh_caudate.nii I then try to resample the extracted volume into FSL MNI152 2mm space, using the registration that comes with FS 5.1 (.dat format): mri_vol2vol --mov MNI305_3D_masks/mask_lh_caudate.nii --targ $FSLDIR/data/standard/MNI152_T1_2mm_brain.nii.gz --reg $FREESURFER_HOME/average/mni152.register.dat --o MNI152_3D_masks/mask_lh_caudate.nii Unfortunately, caudate appears in a clearly incorrect location, both when checking the result with tkmedit2, and when viewing the volumes with freeview. Adding --inv does not fix this either. However, if I simply overlay the volume extracted from MNI305 aparc+aseg on the FSL MNI152 2 mm volume, the location looks just fine. It therefore appears that MNI305 and MNI152 are in the same space, and mri_vol2vol is not needed. Is this correct? Or am I just using an incorrect register.dat file? Thanks!

Re: [Freesurfer] bbregister error

Hi Salil - I'm cc-ing Doug who may be able to help. The error happens when bbregister invokes fslregister, in this particular line of fslregister: set refvol = `stem2fname $SUBJECTS_DIR/$subjid/mri/$fsvol` When run on brainmask.mgz, it returns "ERROR: could not determine file". a.y On Wed, 6 Mar 2013, Salil Soman wrote: > > Thank you for your email.

Divisions for "anterior" and "posterior" insula?
by Maleki, Nasim 13 Mar '13

13 Mar '13

Hi all, I have a hard time relating the boundaries of the insula defined by Freesurfer (Destrieux a2009s) with what is out there in the literature. Most of what is out there is described in terms of anterior and posterior insula, and I'm not sure if most of them match well with what is described in Destrieux et al. paper (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937159/?tool=pubmed) as the "anterior" and "posterior" insula as described below: "The central sulcus of the insula ran antero-inferiorly from the superior segment of the circular segment of the insula. It was a small sulcus that was not always visible on its whole course on the inflated views. It divided the insula in two parts: the short insular gyri [G_insular_short, 18] (anterior) and the long insular gyrus (posterior). Due to their small size, the central sulcus of the insula and the long insular gyri were grouped in the same label [G_Ins_lg_and_S_cent_ins, 17]." Based on these definitions, would it be fair to say: Anterior insula = "G_insular_short" and "S_circular_insula_ant" Posterior insula = "G_Ins_lg_and_S_cent_ins" and "S_circular_insula_inf" Thank you for your help, Nasim

FS 5.2 tkmedit X11 - Xquartz Snow-Leopard
by Garikoitz Lerma-Usabiaga 13 Mar '13

13 Mar '13

Hi FS experts, I just installed 5.2 for Snow Leopard in a machine who already had 5.1. When running tkmedit in 5.1 X11 works well, but when running it from 5.2 it gives the following error: BRODMANN80:~ glerma$ tkmedit bert T1.mgz dyld: Library not loaded: /opt/X11/lib/libGLU.1.dylib Referenced from: /Users/glerma/Apps/freesurfer/tktools/tkmedit.bin Reason: image not found Trace/BPT trap I've seen in the mail list that when this happens, Xquartz should be installed. But, is it a requirement for freesurfer 5.2 in Snow Leopard to run with Xquartz? Should I remove X11 and install Xquartz then? (it may affect other programs and I am reluctant to do it...) Many thanks, Gari

mean thickness covariate, mean area covariate, & mri_anatomical_stats for multiple subjects
by Laura M. Tully 12 Mar '13

12 Mar '13

Hello freesurfers, It appears that prior discussions on the listserv have recommended using mean cortical thickness (rather than ICV) as a covariate for thickness analyses (predominantly recommended by Michael Harms). I have three questions about this: 1. Is there a paper that I could cite that recommends using mean cortical thickness rather than ICV? 2. Would the same logic be applied to surface area analyses? i.e. would it make more sense to use mean surface area as a covariate in surface area analyses? If so, which mean surface area calculation should be used? mri_anatomical_stats can produce both pial and white matter mean surface area stats. 3. Is there a way to run mri_anatomical_stats on multiple subjects at once and write to a tablefile (similar to asegstats2table output)? Thanks! Laura. -- -- Laura M.

Re: [Freesurfer] does mkcontrast-sess correct for multiple comparisons?
by Douglas Greve 12 Mar '13

12 Mar '13

Hi Rosa, the sig maps are uncorrected at the individual level. To correct them, run selxavg3-sess with the -fwhm option. This will compute the FWHM of the residuals. When that is done, look for the fwhm.dat file and get its contents. Did you run this in the subject's native space? If so, then you will need to run a simulation. Let me know and I'll tell you how If you can the analysis in the fsaverage space, then run mri_surfcluster --in sig.nii.gz --thmin TT --sign abs --subject fsaverage --hemi lh --annot aparc \ --csd $FREESURFER_HOME/average/mult-comp-cor/fsaverage/lh/cortex/fwhmXX/abs/th20/mc-z.csd \ --vwsig vwsig.nii.gz --cwsig cwsig.nii.gz --fwhm fwhm.dat --mask mask.nii.gz --sum sum.dat Where TT is the voxel-wise threshold (cluster forming threshold), --sign abs means take positive or negative, XX is the FWHM (rounded up to next integer). The output vwsig is the volume corrected for voxel-wise significance, cwsig is the clusteriwise significance. doug On 3/12/13 8:35 PM, Rosa Lafer-Sousa wrote: > Hi Doug, I am analyzing data for two monkeys and I am under the > impression that I should be correcting each independently for every > contrast I generate.
