Clarification about "Per-Run" Motion Correction and Registration in Preproc-Sess
by Taylor, Johnmark 07 Dec '17

07 Dec '17

Thanks once again for all the help on this. I am running the GLM in native space, typically so that I can get the beta values to use in an MVPA analysis. So it sounds like if you specify per-run motion-correction and registration, and don't tell it to resample to anything (e.g., the MNI brain or the surface), then there's no guarantee that the voxels will properly line up if you want to do, for instance, a single-subject GLM in the subject's native space? So in this case, per-session motion correction would be better so that all the functional volumes in the session are registered properly? > Thank you, this is very helpful!

In what space are you doing the GLM? Usually, the raw data are resampled onto the surface (eg, fmc.fsaverage.lh.sm05.nii.gz), and the GLM is done in this spae.so no registration is needed. > > Apologies for these (probably basic) questions, I just want to make > sure I am crystal-clear on what preproc-sess is doing. > > Cheers, and many thanks, > > JohnMark

PET partial volume correction:mri_gtmpvc error
by Herranz Muelas, Elena 07 Dec '17

07 Dec '17

Dear Freesurfers, I am trying to apply partial volume correction to my PET images, following the steps explained in the PetSurfer wiki. When I run the mri_gtmpvc command, it works fine for most of the subjects but for some of them I get the following error message: /autofs/space/alicudi_002/users/mscat/users/caterina/MR-PET/MSPET06/PET/PET-space Loading input /autofs/space/alicudi_002/users/mscat/users/caterina/MR-PET/MSPET06/PET/PET-space/SUVR.nii.gz done loading input 1 frames $Id: mri_gtmpvc.c,v 1.69.2.1 2016/07/08 19:50:25 zkaufman Exp $ setenv SUBJECTS_DIR /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3 cd /autofs/space/alicudi_002/users/mscat/users/elena/scripts/PVC mri_gtmpvc --i /autofs/space/alicudi_002/users/mscat/users/caterina/MR-PET/MSPET06/PET/PET-space/SUVR.nii.gz --reg /autofs/space/alicudi_002/users/mscat/users/caterina/MR-PET/MSPET06/PET/PET-space/SUVR.reg.lta --psf 6 --seg gtmseg.mgz --default-seg-merge --auto-mask PSF .01 --mgx .01 --o /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3/MSPET06_recon/gtmpvc.output sysname Linux hostname alicudi.nmr.mgh.harvard.edu machine x86_64 user ehmuelas vgthresh 0.001000 nReplace 18 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 40 avail.processors, using 1 Creating output directory /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3/MSPET06_recon/gtmpvc.output Loading seg for gtm /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3/MSPET06_recon/mri/gtmseg.mgz Loading seg ctab /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3/MSPET06_recon/mri/gtmseg.ctab Reading /autofs/space/alicudi_002/users/mscat/users/caterina/3T/recons_fsv5.3/MSPET06_recon/mri/gtmseg.lta Replacing 18 Pruning ctab Checking tissue type ERROR: CheckSegTissueType() tissue type for seg 64 Right-F3orb not set Failed tissue type check And the command line that I ran: mri_gtmpvc --i $path_to_suvr/SUVR.nii.gz --reg $path_to_suvr/SUVR.reg.lta --psf 6 --seg gtmseg.mgz --default-seg-merge --auto-mask PSF .01 --mgx .01 --o $path_to_recon/$subj"_recon"/gtmpvc.output Could you please help me out with this?

Freeview problem: ROIs showing in wrong slice when loaded with certain volumes
by Sims, Sara A 06 Dec '17

06 Dec '17

Hello, I am having an issues with freeview ROIs. When I use the command line to load the orig and the ROIs by themselves they display correctly, however when I display the orig volume and the volume versions of the ROIs- the label ROIs suddenly change to be in the wrong plane. I have done this same thing before and this hasn’t happened. Right now I am having to load just the orig and ROI labels then run the command within freeview to load the label volumes to get it to display all the images at the same time correctly. I would like to do it all in one command line at the same time. Thanks, Sara Sims Graduate Research Fellow University of Alabama at Birmingham Department of Psychology 205-975-4060 snolin(a)uab.edu

Stats test
by Daya P 06 Dec '17

06 Dec '17

Hi all, I have a group of 31 subjects scanned at two time points.I have mean BOLD activation for each region of aparc2009. I would like to test if there is any significant difference in terms of mean BOLD activation between time point 1 and time point 2 in each region, and then introduce thickness as a covariate to see if that explains the differences. Is there any statistical test that you can recommend? Thank you, Daiana

Re: [Freesurfer] Clarification about "Per-Run" Motion Correction and Registration in Preproc-Sess
by Taylor, Johnmark 06 Dec '17

Thank you, this is very helpful! A few quick followup questions: 1) If you don't specifically tell preproc-sess what space to resample too (e.g., by using the "-surface" or "-mni305" flags), does it automatically resample to the subject's anatomical volume, then? 2) If fmc.nii.gz is already registered to the subject's volume, then how come a registration file has to be specified when visualizing GLM results using tksurfer? If fmc.nii.gz is already resampled to anatomical space, then surely any GLM contrasts should be as well, no? 3) If per-run motion correction and registration is specified in pre-proc sess, then there will be a different functional-->structural transformation for each run, correct? If this is the case, then when visualizing session-wide GLM results using tksurfer, which registration file should be specified when loading up the overlay, since there'll be a different registration file for each run? Apologies for these (probably basic) questions, I just want to make sure I am crystal-clear on what preproc-sess is doing.

Infant Atlas

Hi experts, We are presently involved in a project for analyzing MRI data of 1-3 year old children using FreeSurfer. We cannot find a correct infant atlas. From online search, I know that an infant atlas is being developed which will be integrated into FreeSurfer in the future. （link https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4332305/ [https://www.ncbi.nlm.nih.gov/corehtml/pmc/pmcgifs/pmc-logo-share.png]<https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4332305/> A FreeSurfer-compliant consistent manual segmentation of ...<https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4332305/> www.ncbi.nlm.nih.gov We present a detailed description of a set of FreeSurfer compatible segmentation guidelines tailored to infant MRI scans, and a unique data set of manually segmented ... ） Can I know when this will be available? If not soon, is there any other methods for us to generate an infant(kid) atlas? Also I know there are infant atlas from UNC(http://www.med.unc.edu/bric/ideagroup/free-softwares/unc-infant-0-1-2-a…, how can I use this atlas in Freesurfer?

subcortical structures volume
by 郑凤莲 04 Dec '17

04 Dec '17

Hi professor, I am using Freesurfer 6.0 and get the volume of subcortical structures. I want to get the relationship between age and volume. I only have one group, is it necessary to take gender and eTIV as a covariate? If it is necessary, Which statistical analysis should be used? I really appreciate your help. Thanks a lot. Sincerely, Zheng
