Re: [Freesurfer] AC/PC positions and other questions
by François Tadel 15 Jul '13

15 Jul '13

Hi Doug, Thanks for the quick reply. A few more details: > What do you mean by "position" (AC/PC)? Do you mean the col, row, slice? We don't find the actual AC or PC. Yes: 3D coordinates in any identified coordinate systems. For now, we are asking our users to mark those points manually. It would be great to skip that step and have those points placed automatically. We could get the AC point from the linear Talairach transform. To transform the TalXYZ=(0,0,0) for AC to the coordinate system of the surfaces (for instance: lh.pial), should I take the translation found in the file "talairach.xfm" (4th column) ? > What file should I read to get the labels corresponding to the aseg.mgz file? > $FREESURFER_HOME/ASegStatsLUT.txt Is there a file in the segmentation folder I could read it from? We are typically using the results of freesurfer segmentation on computers where FS is not installed... > Is there an easy way to generate surfaces for all the regions defined in aseg.mgz? Ok, mri_tesselate + mris_smooth work well for what I'm doing. Thanks Francois -- François Tadel, MSc MEG / McConnell Brain Imaging Center / MNI / McGill University 3801 rue University, Montreal, QC H3A2B4, Canada

using two vs one scan(s) for optimal surface reconstruction
by Marie Schaer 15 Jul '13

15 Jul '13

Hi all, Small question related to the number of structural runs required for optimal results: I was wondering whether someone tested the assumption that using two scans rather than one improves the segmentation process and the cortical surface reconstruction / thickness estimation? I've not been able to find any publication on it, but maybe my search was not extensive enough. Thanks a lot for your answer, Marie

Got it. Can you send me a listing of the contents of the xfms/ directory? Conversions b/w formats can be done with tkregister2, but the .dat file should normally be there since it's the default format for bbregister.

FSFAST funcroi-sess problem
by Joseph Dien 15 Jul '13

15 Jul '13

I'm using Freesurfer 5.3.0 (well, actually I ran the original analyses with 5.2.0 and then am running this ROI follow-up with 5.2.0, could that be a problem? From the release notes, it didn't look like it would be an issue) Anyway, I've run the following set of commands: funcroi-config -roi /Volumes/Data/CP1/fsfast/secondLevel/CPA.sm05.lh/AR-v-CS/AR-v-CS_HC.wls/HC/roi.AR-v-CS_HC.HC.th2.neg.cluster1.roicfg -annot /Volumes/Data/CP1/fsfast/secondLevel/CPA.sm05.lh/AR-v-CS/AR-v-CS_HC.wls/HC/cache.th20.neg.sig.ocn.annot cluster-001 -analysis CPA.sm05.lh funcroi-sess -roi /Volumes/Data/CP1/fsfast/secondLevel/CPA.sm05.lh/AR-v-CS/AR-v-CS_HC.wls/HC/roi.AR-v-CS_HC.HC.th2.neg.cluster1.roicfg -s CPA003 -d . I get the following output. When I checked the results with: tksurfer fsaverage lh inflated -overlay roi.AR-v-CS_HC.HC.th2.neg.cluster1.nii.gz -fthresh .5 sure enough, it didn't look right. Instead of the cluster, I got speckles all over the surface. I used the Matlab command: [vertex_coords, faces] = read_surf('lh.white'); and found sure enough that the size of the vertex array was only 143827 whereas mri_info indicates that the ocn file has 163842 Any suggestions what I might be doing wrong? Thanks!

Re: [Freesurfer] application of mri_cvs_register question

Hi Matt - The CVS morph under xfms/cvs/ maps the individual anatomical to the CVS template. To map from individual diffusion to the CVS template, you'd have to first use diffusion-to-anatomical affine transform file under xfms/.

pathstats.byvoxel.txt
by Susan Kuo 15 Jul '13

15 Jul '13

Hi Anastasia, I believe the issue I had with the pathstats.byvoxel.txt not displaying the last four values (AD_Avg RD_Avg MD_Avg FA_Avg ) is owing to the fact that trac-all was run with FREESURFER 5.1. I believe that FREESURFER 5.2 may be needed to generate path.pd.trk, and from that, the above values are derived. Is this correct?

Freesurfer for animal data
by Qasim Bukhari 15 Jul '13

15 Jul '13

Dear all, I attended the Seattle course a couple of weeks ago. Actually I m using mice data in my analysis, and I was wondering if I can use freesurfer for that as well ?I understand there is not so much sulci and gyria problem in mice data as in human, however a flattened surface registration and analysis might still be interesting to see. Is it possible at all to do that ? Thanks a lot and best,Qasim Qasim BukhariResearch Assistant and Doctoral CandidateInstitute for Biomedical EngineeringETH and University ZurichWolfgang-Pauli-Strasse 27, HIT E22webpages: MR-pagehttp://www.biomed.ee.ethz.ch/people/sybukhar

Re: [Freesurfer] FreeSurfer: plot activation foci

Dear FreeSurfer team, Firstall, thanks a lot to your great contribution in the neuroscientific and the free software world. I would like to know if is it possible to make a plot activation foci (i.e. example by PySurfer: http://pysurfer.github.io/auto_examples/plot_foci.html) by FreeSurfer directly, and how can it be done?

Generating a fsgd file for regression analyses
by Avram Holmes 15 Jul '13

15 Jul '13

Freesurfer et al., I'd like to try out some simple cortical thickness regression analysis in mri_glmfit. These would be analyses of one continuous score (e.g., Temperament) and several continuous nuisance variables (e.g., Age, IQ, Site, etc). However, before getting started I wanted to run my fsgd and contrast files by the mailing list to make sure I am entering things correctly. If any freesurfer pros have a free moment I've love to hear if I am on the right track. My fsgd file looks like the following: GroupDescriptorFile 1 Title Temp MeasurementName thickness Class Main Variables Temperament Age Scanner Console IQ Input Subj1 Main -2.65 22 3.00 4.00 103.0 Input Subj 2 Main -2.24 24 3.00 3.00 109.0 Input Subj 3 Main -1.82 20 1.00 4.00 121.0 Input Subj 4 Main -1.79 19 3.00 3.00 113.5 Input Subj 5 Main -1.77 19 1.00 3.00 101. 6 .... My contrast1.mat file is: 0 1 0 0 0 0 It is my hope that when I call: mri_glmfit --fsgd GLMFIT/fsgd.txt --y GLMFIT/lh.TEMP.mgh --C GLMFIT/c.txt --surf fsaverage lh --cortex --glmdir GLMFIT/lh.TEMP.output I am prepping to run a regression looking at the relationship between Temperament and cortical thickness, partialing out age, scanner, console, and IQ.
