fsaverage -> fsaverage3
by Itamar Kahn 26 Mar '14

26 Mar '14

Greetings, We would like to downsample surfaces (e.g. using mris_decimate) but we want to duplicate the way it was done with fsaverage (namely, find out how fsaverage3/4/5 were created from the original fsaverage). Also, we wish to be able to project using mri_surf2surf but we don’t have sphere registration available (these are fetal imaging surfaces). Thanks, Itamar _________________________________________________ Itamar Kahn, Ph.

Re: [Freesurfer] glmfit with correlated covariates
by L. Schweren 25 Mar '14

25 Mar '14

Dear FreeSurfer experts, Thank you for your fast reply. We are extracting cortical thickness values for statistical sub-analyses in SPSS (due to corrections required with regard to family relatedness within the data); therefore we want to be a 100% certain that the statistical model we use in SPSS is identical to the model used by mri_glmfit. Can you confirm that, out of the multiple linear regression types listed below, mri_glmfit makes use of the Direct (or Standard) regression model? Type Characteristics Direct (or Standard) . All IVs are entered simultaneously Hierarchical . IVs are entered in steps, i.e., some before others . Interpret: R2 change, F change Forward . The software enters IVs one by one until there are no more significant IVs to be entered Backward . The software removes IVs one to one until there are no more non-significant IVs to removed Stepwise . A combination of Forward and Backward MLR Thank you again for your help, Best wishes, Lizanne Date: Wed, 12 Mar 2014 11:04:00 -0400 From: Douglas Greve <greve(a)nmr.mgh.harvard.edu> Subject: Re: [Freesurfer] glmfit with correlated covariates To: freesurfer(a)nmr.mgh.harvard.edu Message-ID: <53207760.8010809(a)nmr.mgh.harvard.edu> Content-Type: text/plain; charset="iso-8859-1" It is just a standard multiple regression analysis where all regressors are fit simultaneously.

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
