Hello FreeSurfer Developers, This is Erik Jahner, I’m attempting to complete the final step in the tutorial concerning FSFast Functional connectivity walkthrough (http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastFunctionalConnectivityWalkth… ), but for I get the following error when I run the following command: selxavg3-sess -s subj439rest -a fc.lpccseed.surf.lh Mon Jul 4 11:01:41 PDT 2016 rawfunc2surf-sess completed ---------------------------------------- Started at Mon Jul 4 11:01:40 PDT 2016 Ended at Mon Jul 4 11:01:41 PDT 2016 preproc-sess done ------------------------------------------- /Applications/freesurfer/LagStructure/subj439rest Mon Jul 4 11:01:41 PDT 2016 anadir = /Applications/freesurfer/LagStructure/subj439rest/rest/fc.lpccseed.surf.lh DoGLMFit = 1 DoContrasts = 1 UpdateNeeded = 1 ------------------------------------------ ------- matlab output -------------------- matlab: Command not found. ------------------------------------------ ERROR: fast_selxavg3() failed\n I've searched the list and no similar errors have been reported.

cache.th13.neg.sig.cluster.mgh directionality
by Arkadiy Maksimovskiy 08 Jul '16

08 Jul '16

Hello, I apologize if the questions are trivial- I have checked the archives, but could not find anything on this. I have run a t-test between two groups on cortical thickness, and used mri_glmfit-sim for pos, neg, and abs versions. 1. If my FSGD is organized as: Group 1 Group 2 and my matrix file is 1 -1 Would a blue result in an absolute version indicate that Group 1 < Group 2? 2. When running the command: "less" on "cache.th13.pos.sig.cluster.mgh", I am getting 1 significant cluster, however, when running the same command on the "absolute" version of this file, there is nothing significant. Do you know why this might be the case? Much appreciated, Arkadiy

Error with MatlabR2016a and LGI
by Mahtab Farahbakhsh 08 Jul '16

08 Jul '16

Dear FreeSurfer, I am trying to calculate LGI for my images, but it seems like that it doesn't work. I have tried everything, but it's still giving me the same error. I'm using FreeSurfer on a mac and my Matlab version is R2016a. When I try to run "recon-all -s <subj> -localGI", I get this error: ERROR: Matlab is required to run mris_compute_lgi!. I have done these so far: PATH=/Applications/MATLAB_R2016a.app/bin/matlab:$PATH export PATH And my $PATH is: /Applications/MATLAB_R2016a.app/bin/matlab:/usr/local/fsl/bin:/Applications/freesurfer/bin:/Applications/freesurfer/fsfast/bin:/Applications/freesurfer/tktools:/usr/local/fsl/bin:/Applications/freesurfer/mni/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/opt/X11/bin: No such file or directory And when I write getmatlab, I get this: ERROR: Cannot find matlab. Does not exist or is not in path. My original Matlab is in the /Applications folder and I also have a folder named "matlab" in my FreeSurfer folder. Would you please guide me what I should do? Best Regards, Mahtab.

question about volume of the hippocampus
by kjunji＠med.kanazawa-u.ac.jp 07 Jul '16

07 Jul '16

Dear freesurfer developers. I am working at department of neurology in university Hospital, Japan. I am beginner of freesurfer, please forgive me to ask you a basic question. I want to measure the volume of the hippocampus in my patients. I was able to segment the MRI successfully and display the image in freeviewer. However, I could not recognize the way to obtain the volume of the hippocampus. *I saw the "mail acheive" (http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg14679.html) however, I could not understand the way to look at the the aseg.stats. Could you teach me the way for obtaining the volume of the hippocampus? I and very looking forward to hearing from you. Yours sincerely, Junji Komatsu

Dear FS experts, I am planning to use FS to analyze large dataset from population. I am wondering if there were software can automatically check T1 imaging quality for FS? such as monitoring head motion, noise, et al. thanks Lawrence Emory

fslaverage/MNI coordinates
by Li, Baojuan 07 Jul '16

07 Jul '16

Dear Freesurfer experts, I am using MNE (with MEG data) to define my ROIs for a connectivity analysis. I am going through the following steps to get the MNI coordinates of the regions: 1. Morph the subject's brain to fslaverage; 2. Load the inflated surface of fslaverage to MNE analyze; 3. Look for regions that are activated during my task; 3. Use view>show coordinates to show the coordinates of the vertex; 4. The surface RAS (MRI) coordinates are shown; 5. Used these coordinates as MNI coordinates. Because I was using SPM in the past and am quite new to freesurfer, I strongly hope someone can help me to check if I have done it correctly. Thank you so much for your help! Best wishes, Baojuan

BrainSeg Volume Clarification
by Cook, Bernie 07 Jul '16

07 Jul '16

All, Upon looking at online forums and the FreeSurfer wiki, I have come to the understanding that "BrainSeg" volume in the aseg.stats file includes all cortical and subcortical gray matter, cerebellar gray matter; cortical, subcortical and cerebellar white matter and white matter hypointensities; and all ventricle volumes, but excludes the brain stem. When using the aseg.stats file for included subject "bert" to check my understanding of which volumes are used, I cannot seem to produce identical "BrainSegVol-to-TIV" ratios. I am adding the following volumes, all in mm^3, to obtain the brain volume: TotalGrayVol: 658087.056198 CorticalWhiteMatterVol: 485627.161537 Left-Lateral-Ventricle: 6562.6 Left-Inf-Lat-Vent: 228.3 Left-Cerebellum-White-Matter: 15708.2 3rd-Ventricle: 997.5 4th Ventricle: 1714.2 Right-Lateral-Ventricle: 6039.9 Right-Inf-Lat-Vent: 160.3 Right-Cerebellum-White-Matter: 15694.5 5th-Ventricle: 14.1 WM-hypointensities: 1002.6 Sum of individual measures: 1191836.418 Output of BrainSegVol: 1193318 And when normalizing the subject's brain volume by the eTIV measure (1594882.911364), I obtain the following: Individual measures: 0.7473 BrainSegVol-to-eTIV: 0.7482 Is there a reason that these two measurements are slightly off? I'm wondering whether there's certain volumes used for BrainSegVol that I missed, or ones that I included that would not be present in the output. Moreover, I'm wondering whether this could potentially be a result of using surface volumes (BrainSegVol) versus using both surface and voxel-space calculations (my addition method). Any help is appreciated. Thank you in advance. Best, [1455168447449_PastedImage] Bernard L.
