Percent signal change after resampling and combining FEAT analyses
by Manuel Spitschan 25 Mar '14

25 Mar '14

Dear FreeSurfer experts, I've performed a few first-level analyses of BOLD data with FSL, and have followed the instructions on the FS Wiki (http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/FslGroupFeat) to sample the COPEs of each run to a common surface (fsaverage) and run a fixed-effects analyses using 'mri_glmfit' across the runs. The resulting gamma.mgh contains the COPEs per vertex across the runs. How would I find out the appropriate scaling factor and the baseline image to calculate percent signal change per vertex following these analysis steps? Any help would be appreciated. Thanks in advance, Manuel Spitschan

thickness for "subcortical structures"
by Francesco Puccettone 25 Mar '14

25 Mar '14

Hello, I've read that cortical thickness analyses are limited to the cortex and cannot be used to examine subcortical grey matter. But does "subcortical grey matter" refer to deep gray matter structures such as the hippocampus, the basal ganglia or the nucleus accumbens - all of which are still technically part of the "cerebral cortex" - or does it in fact refer to gray matter nuclei surrounded by white matter, for which it would not be possible to model a white & a pial surface? Thank you! Francesco

Can we use both -use-gpu and -openmp options in recon-all?
by Tran, Kevin (NIH/NIMH) [C] 25 Mar '14

25 Mar '14

Hi, I have posted a question about the error while using recon-all command with -use–gpu option on a CentOS 6 machine a while back. CUDA Error in file 'mriconvolve_cuda.cu' on line 945 : unload of CUDA runtime fa iled. Abort (core dumped) ERROR: mri_ca_register with non-zero status 134 The problem apparently came from this command mri_ca_register_cuda -nobigventricles -T transforms/talairach.lta -align-after -mask brainmask.mgz norm.mgz /opt/freesurfer/average/RB_all_2008-03-26.gca transforms/talairach.m3z We are wondering if it was OK to change the recon-all script so that we would enable OpenMP for this mri_ca_register command but use GPU for the rest of recon-all script? That is, we would replace line 2273 in recon-all from if($UseCuda) set cmd = (mri_ca_register_cuda) To if($UseCuda) set cmd = (mri_ca_register) So, with the –openmp option, this command will run with multiple cores. By not using GPU for this command, we can avoid the CUDA Error message. However, we are wondering if it's OK that we combined both -use–gnu and –openmp? Could you help us out? -- Kevin Tran, Contractor UNIX System Administrator The National Institutes of Health NIMH, Laboratory of Brain and Cognition 10 Center Drive, Room 4C215 Bethesda MD 20892-1366 kevintran(a)mail.nih.gov

Hi Doug, Thanks for your help. I got the attached output for the MD calculation - do you know if these are reasonable results ? how come the values of the corpus-callosum so different ?

Re: [Freesurfer] major lobes
by Juranek, Jenifer 25 Mar '14

Hi Doug, I recently saw your solution to a reported problem with grabbing StrictLobes WM & GM (posted on the Freesurfer forum 12/04/2013; thread title= major lobes). I have successfully grabbed the StrictLobes WM, but I am having trouble with the GM. According to the forum (posted 12/04/2013), the solution that worked was a link (you provided) to download a new binary for mri_annotation2label from the following location:ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_… However, this link appears to be broken now that I am attempting to utilize your fix on my RHEL6 workstation. I checked the download site , but there is no new version of Freesurfer since May 2013. Any chance you could provide a link to the new binary for mri_annotation2label you had made available back in Dec 2013? Many Thanks, Jenifer Juranek

Convert volume label to surface label
by Karen Marie Sandø Ambrosen 25 Mar '14

25 Mar '14

Hi Freesurfer experts, I have a volume label only which is only different from zero in the white matter-gray matter boundary. I am trying to convert this volume label to a surface label in order to visualize it in tksurfer. I am using mri_vol2surf: mri_vol2surf --mov volume_label.nii --out volume_label2surf.mgh --out_type mgh --hemi lh --regheader H01 --surf white --ref volume_label.nii However, when I load this surface as an overlay in tksurfer, to check the correctness, the original surface is not fully covered by the surface created by mri_vol2surf. Is there any way to make the surface fully cover the original surface so it doesn't look speckled? After creating the surface I want to convert the surface to labels by mri_cor2label and finally to an annotation file by mris_label2annot. Best, Karen

Ciao Eugenio, thank you very much for your prompt and kind response.Yes, I'm looking average over the entire support of the path distribution and their differences among 2 pathological and 1 control groups.I haven't a strong hypothesis.When I performed MANOVA, Tukey or Bonferroni post hoc find differences but p for Wilk's lambda is not significant.If I understand your suggestion, I should performed a simple t-test for each tract.Bur, for Bonferroni's correction, I should consider: A. 0.05/18 tracts X 3 groups (I suspected that it should be too hard)orB. 0.05/18 tractsor more simplyC. 0.05/3 groups Thanks, Stefano ----Messaggio originale---- Da: iglesias(a)nmr.mgh.harvard.edu Data: 24-mar-2014 22.11 A: <stdp82(a)virgilio.it>, "Freesurfer support list"<freesurfer(a)nmr.mgh.harvard.edu> Ogg: Re: [Freesurfer] TRACULA statistics concern Ciao Stefano, can you be a bit more specific about what you're exactly trying to to? Am I correctly assuming that you are looking at differences between your groups? Are you looking at average FA/MD/RD/AD over whole tracts, or at values along them? Do you have any strong hypothesis on which tract will give you differences? In any case, people often look at the tracts of interest one by one (which a simple test, e.g., t-test) and then apply Bonferroni correction.
