Binary Mask Overlay
by Dincer, Aylin 12 Jan '17

12 Jan '17

Hi FreeSurfer Team, I used QDEC to do a group analysis and from that I generated a surface-based mask using the command "mri_binarize --i sig.mgh --min 3 --o mask.mgz" Ultimately, I would like to overlay this mask on an individual subject (other than the fsaverage "lh.inflated" surface). Using freeview, I uploaded the lh.inflated surface of an individual subject and tried to overlay the "mask.mgz" file, but it doesn't seem to work. There are no error messages and it is visible in the "overlay" drop down menu. However, nothing appears on the surface. The chosen subject was in the QDEC group analysis and all subjects were run with FreeSurfer v5.3. I did try this on the fsaverage surface and the mask is visible. What are your suggestions for this overlay issue? Let me know if you need any more information!

error: mean: DIM must be an integer and a valid dimension / selxavg3-sess with octave
by Michael Schirner 12 Jan '17

12 Jan '17

Dear FreeSurfers, I just wanted to share a solution for an issue that can arise when running selxavg3-sess with octave instead of Matlab. In fast_selxavg3.m (which is called by selxavg3) there is a line (579 in my version) that computes the mean of an array by calling the mean function with the DIM argument, which specifies the dimension over which the average should be computed (4th dimension in this case): rho1mn.vol = mean(rho1.vol,4); This line will throw an error under octave if the number of dimensions of the array rho1.vol is smaller than 4. In Matlab it will simply return the array. To solve this issue for octave users one can use a simple if-else statement to check for the number of dimensions and return the unchanged volume if the number of dimensions is smaller than four or if the fourth dimension is a singleton, like this: if 4 > ndims(rho1.vol) || size(rho1.vol,4) == 1 rho1mn.vol = rho1.vol; else rho1mn.vol = mean(rho1.vol,4); end Best, Michael

bbregister surfaces
by Christopher Markiewicz 12 Jan '17

12 Jan '17

Hi all, According to https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg25476.html, bbregister uses the white matter surface and cortical thickness measures to perform its registrations, though there was some possibility of using the pial surface in further releases. I just want to verify that this is still the case, and the pial surface is not currently being used. Thanks, Chris Markiewicz

pial surface vs. aparc segmentation inconsistency
by Gabor Perlaki 12 Jan '17

12 Jan '17

Dear all, In some of our subjects the border of ctx_lh_parahippocampal (green color) is inconsistent with the border of pial surface (red color) in the sense that some small region within the pial surface is segmented as cerebellum (orange) coming from the subcortical segmentation stream. This problem is present in all three planes. It is hard to decide whether the colored border of ctx_lh_parahippocampal or the pial surface is more realistic, but it would be nice to know which one is used for the parahippocampal statistics in lh.aparc.stats file. Do I need to correct for this inaccuracy? How should I correct this type of missegmentation? Best Regards, Gabor <petzinger.gabor(a)gmail.com>

Editing annot files
by Martin Juneja 12 Jan '17

Hi, I was wondering if there is any way to edit annot file e.g. I would like to edit *lh.Yeo2011_7Networks_N1000.annot* file in such a way when I overlay this file in freeview, I just display limbic network from Yeo 7 network atlas and hide other 6 networks. I would prefer to use MATLAB for this but would really appreciate any other simple way to do that. Thanks.

Hi experts, I ran the command $recon-all -all -subjid 0696 I have got these error messages *CORRECTING DEFECT 46 (vertices=66623, convex hull=8931)* *Excessive topologic defect encountered: could not allocate 322592700 edges for retessellation* *Cannot allocate memory* *Linux xubuntu-VirtualBox 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:41:14 UTC 2012 i686 i686 i386 GNU/Linux* I am not sure if this problem came from the insufficient memory on my computer. Otherwise, please let me suggestions for solving this problem. Thank you, Aziz.

Hello FreeSurfer Developers, I am attempting to repeat the group analysis with the tutorial data on FreeSurfer website, as described on the FsTutorial/GroupAnalysis ( https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis) But I received an error message when running the mri_glmfit command lines. At first, the command lines that I types: mri_glmfit --y xiuyi_lh_thickness.10.mgh --fsgd gender_age.fsgd dods --C lh-Avg-thickness-age-Cor.mtx \ —-surf fsaverage lh \—-cortex —glmdir xiuyi_lh.gender_age.glmdir Errors: MRISread(/Users/xiuyi/Documents/tutorial_data/buckner_data/tutorial_subjs/ group_analysis_tutorial/glm/fsaverage/surf/lh. —-cortex): could not open file No such file or directory mri_glmfit: could not read surface /Users/xiuyi/Documents/tutorial_data/ buckner_data/tutorial_subjs/group_analysis_tutorial/glm/fsaverage/surf/lh. —-cortex No such file or directory Then I changed the command lines, replacing "surf fsaverage lh.white" with "surf fsaverage lh". The exact command lines are: mri_glmfit --y xiuyi_lh_thickness.10.mgh --fsgd gender_age.fsgd dods --C lh-Avg-thickness-age-Cor.mtx \ —-surf fsaverage lh.white \—-cortex —glmdir xiuyi_lh.gender_age.glmdir The error message is: gdfReadHeader: reading gender_age.fsgd INFO: DeMeanFlag keyword not found, DeMeaning will NOT be done. Continuous Variable Means (all subjects) 0 age 57.175 26.6006 Class Means of each Continuous Variable 1 genderFemale 59.1429 2 genderMale 55.0000 INFO: gd2mtx_method is dods *ERROR: Option fsaverage unknown.* I have searched the list and found this type of error has been reported by another person but no reply was found.(https://mail.nmr.mgh. harvard.edu/pipermail//freesurfer/2010-May/014401.html) 1) FreeSurfer Version: freesurfer-Darwin-lion-stable-pub-v5.3.0 2) Flatform: macOS Sierra version 10:12 Thank you for your reply.
