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

FSL registration
by Jones, Richard 29 Apr '14

29 Apr '14

I have T1 data that has been run through freesurfer and I want to apply the subcortical parcellations from that analysis to some QSM data. The mailing list and website refer to using reg-feat2anat but this require an existing feat directory. If I make a "pseudo" feat directory with my QSM data so that I can use reg-feat2anat does it just need to contain the subfolder reg containing the the QSM data as "example_func.nii" and the registration matrix from using FLIRT to register the QSM data to MNI space as "example_func2standard.mat", or is there something else that needs to be included? Thanks, Richard

incongruent coordinates in freeview and *sig.cluster.summary
by charujing123 29 Apr '14

29 Apr '14

Hi all, I have done group analysis and see it in freeview. Also I can see my sig.cluster.summary file to find clusters those survived. As I know, the MNIX MNIY MNIZ in the cluster summary file is coordinates for the maximum. The coordinate system is MNI305. Also I input the vertex number at the maximum in freeview, but it echo different coordinate for the vertex from that in cluster summary file. Why? Another question. There is "RAS" symbol at the bottom of freeview window. However I see the coordinates : inferior, posterior, left is negtive, superior, anterior,and right is positive. I suspect the coordinate system is LPI. Is that right? Thanks. All the best. Rujing Zha 2014-04-26 charujing123
