re finding sulcal folding values
by Anna Jonsson 30 Apr '14

30 Apr '14

Hi I would like get a mean sulcal folding value per hemisphere and roi data. I have two questions: Is possible do sulcal depth analysis using qdec? And What is the exact command to pass to mris_anatomical_stats to get a mean sulcal depth value /per hemisphere? I have tried some few variations with no luck. Thank you for your help, Kind Wishes, Anna

repost: mri_convert Siemens Skyra .IMA CentOS5.7 FS5.3
by prasser 29 Apr '14

29 Apr '14

Hi, I am still having some concerns using mri_convert on Skyra volumes that I'm hoping can please be addressed. On this occasion I have used mri_convert to convert a single dicom file to nifti from a volume collected on a siemens Skyra scanner using Freesurfer5.3 on CentOS5.7. When viewing this nifti image using tkmedit it appears 'cut-up' over many sagittal slices (please see attached) rather than the whole image appearing on one plane. Not sure if this is an issue with tkmedit or mri_convert? This problem persists if i convert the entire volume, with this 'cutting' appearing as vertical lines in the image. This is also the case when using the new mri_convert patch for OS X. Lastly, I can upload a dicom file if needed. Thanks, Paul

p values for within-subject t maps
by JacobML＠nmr.mgh.harvard.edu 29 Apr '14

29 Apr '14

---------- Forwarded message ---------- Hello Doug et al., I was wondering if anyone could give me some information about whether a p value can be associated with t maps generated in individual subjects (across one or two runs) for fMRI data. When doing group contrasts an uncorrected p value can be assigned based on the number of subjects (using that to determine degrees of freedom). However, what are the degrees of freedom for within subject analyses? Does it relate to number of TRs at all? The question stems from wishing to state the uncorrected p value associated with t thresholds from these maps that we used to extract BOLD timecourses. Thank you!

(Can never tell with R/L). So, FSLview is reading the orientation info correctly. Orientation, as coded in the NIFTI, is a completely separate issue from how a given viewing tool chooses to display the data. You may not like the manner in which FSLview displays the data, but it is respecting the orientation info. cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: mharms(a)wustl.edu From: "stdp82(a)virgilio.it" <stdp82(a)virgilio.it> Reply-To: "stdp82(a)virgilio.it" <stdp82(a)virgilio.it> Date: Tuesday, April 29, 2014 3:20 PM To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu>, "Harms, Michael" <mharms(a)wustl.edu> Subject: R: Re: [Freesurfer] R: Re: R: Re: R: Re: R: Re: thalami mask (nii.gz) to import in FSL Please, see the snapshot attached.

Hi Michael, please, see the file attached. They are reffered to FS and FSL visualization of the same file (R_thalamus overlapped on T1).

What matters is that the A/P/S/I/L/R labels are correct in FSLview, in which case the orientation info is read just fine, and it is solely a matter of how FSLview choses to display data that doesn't have an RAS/LAS orientation. cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: mharms(a)wustl.edu From: "stdp82(a)virgilio.it" <stdp82(a)virgilio.it> Reply-To: "stdp82(a)virgilio.it" <stdp82(a)virgilio.it>, Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Date: Tuesday, April 29, 2014 1:19 PM To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] R: Re: R: Re: thalami mask (nii.gz) to import in FSL Hi Bruce, in tkmedit the orientation is ok.

Problem with Monte Carlo Simulation
by Jacqueline Elaine Fitzgerald 29 Apr '14

29 Apr '14

Hi, I am having problem when running the Monte Carlo script. The script seems to fail after only a few simulations but it does not give me any error message, it just says 'killed'. I am running it on 126 participants (2 groups of 63) and I have tried it on a number of different measures (sulc, area etc.). I thought it may be an space issue but I cleared all other files but that did not seem to make any difference. This is what is printed out on the terminal: [fitzgeje@lonsdale01 qdec]$ mri_glmfit-sim --glmdir Rh_JacobianW_15 --sim mc-z 10000 1.3 mc-z.negative --sim-sign neg --overwritecmdline mri_glmfit --y /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/y.mgh --fsgd /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/qdec.fsgd dods --glmdir /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15 --surf fsaverage rh --label /projects/pi-lgallagh/HPC_12_00408/fsaverage/label/rh.cortex.label --C /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/contrasts/rh-Avg-Intercept-jacobian_white.mat --C /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/contrasts/rh-Diff-ASD-CTRL-Intercept-jacobian_white.mat WARNING: unrecognized mri_glmfit cmd option dods SURFACE: fsaverage rh /home/support/apps/apps/freesurfer/4.5.0/bin/mri_glmfit-sim--glmdir Rh_JacobianW_15 --sim mc-z 10000 1.3 mc-z.negative --sim-sign neg --overwrite$Id: mri_glmfit-sim,v 1.1.2.20 2009/07/16 16:36:47 greve Exp $Thu Apr 24 18:58:31 IST 2014Linux lonsdale01.cluster 2.6.32-358.23.2.el6.x86_64 #1 SMP Wed Oct 16 11:13:47 CDT 2013 x86_64 x86_64 x86_64 GNU/Linuxfitzgejesetenv SUBJECTS_DIR /projects/pi-lgallagh/HPC_12_00408/FREESURFER_HOME /home/support/apps/apps/freesurfer/4.5.0DoPoll = 0DoPBSubmit = 0DoBackground = 0DiagCluster = 0gd2mtx = dodsfwhm = 21.770250nSimPerJob = 100001/1 Thu Apr 24 18:58:31 IST 2014mri_glmfit --y /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/y.mgh --C Rh_JacobianW_15/tmp.mri_glmfit-sim-21064/rh-Avg-Intercept-jacobian_white.mtx --C Rh_JacobianW_15/tmp.mri_glmfit-sim-21064/rh-Diff-ASD-CTRL-Intercept-jacobian_white.mtx --mask Rh_JacobianW_15/mask.mgh --sim mc-z 10000 1.3 Rh_JacobianW_15/csd/mc-z.negative.j001 --sim-sign neg --fwhm 21.770250 --fsgd Rh_JacobianW_15/y.fsgd dods --label /projects/pi-lgallagh/HPC_12_00408/fsaverage/label/rh.cortex.label --surf fsaverage rh whiteINFO: ignoring tag Creator INFO: ignoring tag SUBJECTS_DIR INFO: ignoring tag SynthSeed reading group avg surface area 822 cm^2 from fileReading in average area /projects/pi-lgallagh/HPC_12_00408//fsaverage/surf/rh.white.avg.area.mghreading group avg surface area 822 cm^2 from fileReading in average area /projects/pi-lgallagh/HPC_12_00408//fsaverage/surf/rh.white.avg.area.mghsimbase Rh_JacobianW_15/csd/mc-z.negative.j001gdfReadHeader: reading Rh_JacobianW_15/y.fsgdINFO: demeaning continous variablesContinuous Variable Means (all subjects)Class Means of each Continuous Variable1 groupASD2 groupCTRLINFO: gd2mtx_method is dodsReading source surface /projects/pi-lgallagh/HPC_12_00408//fsaverage/surf/rh.whiteNumber of vertices 163842Number of faces 327680Total area 65020.765625AvgVtxArea 0.396850AvgVtxDist 0.717994StdVtxDist 0.193566INFO: fwhm2niters: NOT fixing group surface areaSurface smoothing by fwhm=21.770250, niters=441.000000 $Id: mri_glmfit.c,v 1.138.2.15 2009/07/27 17:43:10 greve Exp $cwd /projects/pi-lgallagh/HPC_12_00408/qdeccmdline mri_glmfit --y /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/y.mgh --C Rh_JacobianW_15/tmp.mri_glmfit-sim-21064/rh-Avg-Intercept-jacobian_white.mtx --C Rh_JacobianW_15/tmp.mri_glmfit-sim-21064/rh-Diff-ASD-CTRL-Intercept-jacobian_white.mtx --mask Rh_JacobianW_15/mask.mgh --sim mc-z 10000 1.3 Rh_JacobianW_15/csd/mc-z.negative.j001 --sim-sign neg --fwhm 21.770250 --fsgd Rh_JacobianW_15/y.fsgd dods --label /projects/pi-lgallagh/HPC_12_00408/fsaverage/label/rh.cortex.label --surf fsaverage rh white sysname Linuxhostname lonsdale01.clustermachine x86_64user fitzgejeFixVertexAreaFlag = 1UseMaskWithSmoothing 1fwhm 21.770250niters 441.000000OneSampleGroupMean 0y /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/y.mghlogyflag 0usedti 0FSGD Rh_JacobianW_15/y.fsgdlabelmask /projects/pi-lgallagh/HPC_12_00408/fsaverage/label/rh.cortex.labelmask Rh_JacobianW_15/mask.mghmaskinv 0glmdir (null)IllCondOK 0DoFFx 0Loading y from /projects/pi-lgallagh/HPC_12_00408/qdec/Rh_JacobianW_15/y.mghINFO: gd2mtx_method is dodsMatrix condition is 1/projects/pi-lgallagh/HPC_12_00408/fsaverage/label/rh.cortex.label /projects/pi-lgallagh/HPC_12_00408/fsaverage/label/rh.cortex.labelFound 149926 points in label.Found 149926 voxels in masksearch space = 75188.6DOF = 124thresh = 1.3, threshadj = 0.99897 Starting simulation sim over 10000 trialsSmoothing done, nsteps = 441, tsec = 69.733Smoothing done, nsteps = 441, tsec = 69.799Smoothing done, nsteps = 441, tsec = 69.754Smoothing done, nsteps = 441, tsec = 69.749Smoothing done, nsteps = 441, tsec = 69.743Smoothing done, nsteps = 441, tsec = 69.749Smoothing done, nsteps = 441, tsec = 69.737Smoothing done, nsteps = 441, tsec = 69.738Smoothing done, nsteps = 441, tsec = 69.734Smoothing done, nsteps = 441, tsec = 69.806Smoothing done, nsteps = 441, tsec = 70.012Smoothing done, nsteps = 441, tsec = 70.139 Killed Any suggestions that may help?

Xhemi: vertex-wise volume asymmetry analysis?
by Yizhou Ma 29 Apr '14

29 Apr '14

Dear freesurfer experts, I am working on a project on cortical asymmetry and I have analyzed vertex-wise cortical thickness/surface area asymmetry. However, I noticed that Freesurfer doesn't not seem to facilitate such analysis for gray matter volume, as after running surfreg -xhemi there is no ?h.volume file in subject/xhemi/surf. I searched the literature and found studies on gray matter density asymmetry with VBM and ROI-based volume asymmetry. Is it true that Freesurfer doesn't offer vertex-wise volume asymmetry analysis? And may I know the rationale? Thanks, Cherry
