Permission denied mri_surf2surf
by Ellen Ji 09 Sep '20

09 Sep '20

External Email - Use Caution Dear experts, I created a loop for mri_surf2surf so that it would run for 300+ subjects. For most of them, it ran successfully. However, it did not work for 30 subjects. I then went to investigate one by one and I am getting a Permission denied error for some reason. I confirm that recon-all has been performed and also that I have read/write/execute permissions. See below for the log. Any ideas why this could be happening to specific subjects? mri_surf2surf \ --srcsubject fsaverage_sym \ --trgsubject SPN01_CMH_0079_01 \ --hemi lh \ --sval-annot fsaverage_sym/label/lh.500_sym.aparc.annot \ --tval SPN01_CMH_0079_01/label/lh.500_sym.aparc.annot Setting mapmethod to nnf 7.1.0 setenv SUBJECTS_DIR /home/eji/projects/spins/preproc/freesurfer/subjects/w0 cd /home/eji/projects/spins/preproc/freesurfer/subjects/w0 mri_surf2surf --srcsubject fsaverage_sym --trgsubject SPN01_CMH_0079_01 --hemi lh --sval-annot fsaverage_sym/label/lh.500_sym.aparc.annot --tval SPN01_CMH_0079_01/label/lh.500_sym.aparc.annot sysname Linux hostname nu2 machine x86_64 user eji srcsubject = fsaverage_sym srcval = (null) srctype = trgsubject = SPN01_CMH_0079_01 trgval = SPN01_CMH_0079_01/label/lh.500_sym.aparc.annot trgtype = srcsurfreg = sphere.reg trgsurfreg = sphere.reg srchemi = lh trghemi = lh frame = 0 fwhm-in = 0 fwhm-out = 0 label-src = (null) label-trg = (null) OKToRevFaceOrder = 1 UseDualHemi = 0 Reading source surface reg /home/eji/projects/spins/preproc/freesurfer/subjects/w0/fsaverage_sym/surf/lh.sphere.reg Loading source data Reading surface file /home/eji/projects/spins/preproc/freesurfer/subjects/w0/fsaverage_sym/surf/lh.orig reading colortable from annotation file... colortable with 161 entries read (originally /scratch/tmpdir.annot2std.28231/seg.1.073.xhemi.ctab) Reading target surface reg /home/eji/projects/spins/preproc/freesurfer/subjects/w0/SPN01_CMH_0079_01/surf/lh.sphere.reg Done Using surf2surf_nnfr() Mapping Source Volume onto Source Subject Surface surf2surf_nnfr: building source hash (res=16).

Re: [Freesurfer] interpreting file (cache.th13.abs.y.ocn.dat) from longitudinal vertex-wise analysis
by Rizvi, Batool 08 Sep '20

External Email - Use Caution Thanks for the info, Dr. Greve! So for the files I used for the --y argument were stacked files of this file: lh.long.thickness-spc.fwhm10.fsaverage.mgh or rh.long.thickness-spc.fwhm10.fsaverage.mgh. So would my interpretation of the ocn.dat file be that each value is the symmetrized percent change in thickness of the significant cluster for each subject? Thanks again, Batool

BrainSegNotVent

External Email - Use Caution Hello, I am a student learning free surfer. I was able to obtain intracranial volume by running recon-all –i file.dcm –subject bert –autorecon1 and then mri_segstats --subject bert --etiv-only How can I obtain the BrainSegNotVent volume? I have tried mri_segstats --subject bert --brain-vol-from-seg however, “ERROR: must specify a segmentation volume” Can this be calculated using the data from autorecon1, or do I need to run -all? Which segmentation do I need to specify?

interpreting file (cache.th13.abs.y.ocn.dat) from longitudinal vertex-wise analysis
by Rizvi, Batool 08 Sep '20

08 Sep '20

External Email - Use Caution Hi FreeSurfer team, After running longitudinal FS, and running mri_glmfit using files that measured spc, we found clusters associated with our continuous variable (WMH volume) after controlling for other covariates. I was wondering though, do the values found in cache.th13.abs.y.ocn.dat reflect the change in thickness (as measured by spc) for each subject of the cluster found to be significantly associated? I read other posts that it was a value of thickness of each cluster, but I wasn't sure if the same was true for a longitudinal analysis (spc), as the file contains both positive and negative numbers. Thanks so much for your help! Batool

External Email - Use Caution Hi, Freesurfer Team My name is Wei Shao, as you can see, whenever I tried to Freeview Inflated image , it gives me the picture with mosaic. I was wondering this is because of hardware or the setting? Thanks Best, Wei [image: 3D freesurfer.PNG]

MEMPRAGE vs. MP2RAGE
by Caspar M. Schwiedrzik 08 Sep '20

08 Sep '20

External Email - Use Caution Hi! I was wondering whether the issues with surface reconstruction from MP2RAGE data that were reported for Freesurfer v5.1 in Fujimoto et al., 2014 still persist in more recent releases of Freesurfer, and whether there is information to what extent they apply to 3T data? Thank you! Caspar
