nuiterations question
by Floris van Vugt 25 Aug '17

25 Aug '17

Dear Freesurfer developers and community, I am using recon-all as part of a pipeline and I am wondering about how to control the non-uniform intensity correction. When I run `recon-all -help` I get: -nuiterations Number of iterations in the non-uniform intensity correction. Default is 1. However, when I run `recon-all -i structural.nii -subjid foo -sd . -nuiterations 7` I get: ERROR: Flag -nuiterations unrecognized. -nuiterations 7 Linux colossus 4.4.0-92-generic #115-Ubuntu SMP Thu Aug 10 09:04:33 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux recon-all -s exited with ERRORS at Wed Aug 23 15:27:55 EDT 2017 For more details, see the log file To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting I am running this version of Freesurfer: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c Is this option deprecated? But then why is it still listed under freesurfer -help? Thanks, Floris -- Floris van Vugt, Ph.D. Motor Control Lab, Psychology Dept.

Tracula - QA for Forceps Minor
by Abigail Waters 25 Aug '17

25 Aug '17

Hello - We've processed approximately 500 DTI scans using Tracula and are in the process of visually inspecting the forceps minor for errors. For subjects with dramatic errors (see image 1) we will be redoing the -path step of Tracula with control points set to 7 and reinit = 1. Is this an appropriate solution? In order to generate the fminor_PP_avg33_mni_bbr_cpts_7 files, would we need to redo the whole pipeline, or just parts of it? We would also like to know if any of the following issues described below are errors or normal variation in white matter tracts: 1. Spread of white matter at the ends of the curve (see image 2) 2. Overlapping of the white matter across hemispheres in the prefrontal region (see image 3) 3. Non-smooth surfaces with small protrusions along the length of the forceps minor (see image 4_1 and 4_2) 4. Slightly larger single protrusions of white matter (see image 5) And if so, would increasing the number of control points to 7 increase the quality of the reconstruction? Please let me know if you need any additional information. Best Abby

recon-all
by John Anderson 25 Aug '17

25 Aug '17

Dear FS experts, Attached is a snapshot for orig.mgz overlayed by wm.mgz for one of my recons which finished with no errors. I am reviwing the data and I see a lot of holes in the brain stem, Are these needs to be filled manually. Do you recommend to fill this type of holes or just the ones in the hemispheric white matter? Thanks in advance John

Skull striping problems
by MATEUS ROZALEM ARANHA 25 Aug '17

25 Aug '17

Hi! When I run recon-all on my data, some skull and dura is left behind and affects the surfaces and the parcellation. I re-run the data using a lower watershed (I tried 20, 15, 10 and 05). The brainmask changed, but the remaining skull still affects the parcellation and surfaces. My doubt is: when I re-run my data using a lower watershed value, does it automatically create new surfaces and volumes or not? If not, how can I reset it? Best Mateus

Re: [Freesurfer] recon-all error
by Cara Bohon 24 Aug '17

24 Aug '17

This is the first time I have had the message that it exited with errors. The first times I ran it, it just stopped and the log file ended without a summary statement of why the job stopped. I assumed that time was because I was running it on a cluster with a 24 hour time limit, so I extended the job to 48 hours and started the job again - this time I got the error described below. How long is reasonable to be stuck on fix topology for one hemisphere? I guess my fear was that if it hadn't finished in 48 hours, there was something wrong. > does this happen every time you run it?

Re: [Freesurfer] recon_all error on MacOS 10.12.13 Sierra: during mris_smooth. dyld: lazy symbol binding
by Fred Lado 24 Aug '17

24 Aug '17

Dear FS gurus, I just want to give some feedback on an error message that has bedeviled some of us for the last few months even after running fs_update and turning off SIP. I have been getting this error when I ran mri_coreg or mris_convert: dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address Referenced from: /Applications/freesurfer/bin/../lib/gcc/lib/libgomp.1.dylib Expected in: /usr/lib/libSystem.B.dylib In my case there were multiple versions of libgomp.1.dylib. One in the current Freesurfer 6.0 install, one in the gcc-7.1 compiler library that I recently installed (after I ran into this error) and the third from an ANFI install from 2013. When I rearranged the order of the PATH as shown, the error went away. This was my old path: /usr/local/bioimagesuite35:/usr/local/bioimagesuite35/sbin:/usr/local/bioimagesuite35/bin:/usr/local/bioimagesuite35/bin:/Users/fred/Dropbox/Research_Scripts/EpiSurg-iElvis/iELVis/iELVis_BASH:/Users/fred/Dropbox/Research_Scripts/Linux-Scripts:/Applications/MATLAB_R2015a.app/bin/:/usr/local/cuda/bin:/usr/local/AFNI:/usr/local/fsl/bin:/Applications/freesurfer/bin:/Applications/freesurfer/fsfast/bin:/Applications/freesurfer/tktools:/usr/local/fsl/bin:/Applications/freesurfer/mni/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin:/usr/local/fsl/bin:/usr/local/afni This is my new path: /Users/fred/Dropbox/Research_Scripts/EpiSurg-iElvis/iELVis/iELVis_BASH:/Users/fred/Dropbox/Research_Scripts/Linux-Scripts:/usr/local/gcc-7.1/bin:/Applications/MATLAB_R2015a.app/bin/:/Applications/freesurfer/bin:/Applications/freesurfer/fsfast/bin:/Applications/freesurfer/tktools:/usr/local/fsl/bin:/Applications/freesurfer/mni/bin:/usr/local/fsl/bin:/usr/local/AFNI:/usr/local/bioimagesuite35:/usr/local/bioimagesuite35/sbin:/usr/local/bioimagesuite35/bin:/usr/local/bioimagesuite35/bin:/usr/local/cuda/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin:/usr/local/fsl/bin:/usr/local/afni Best, Fred Fred Lado, MD PhD Director, Epilepsy - Central and Eastern Regions Northwell Health 917-608-1881 (mobile) 516-325-7000 (practice) 516-325-7001 (fax) flado(a)northwell.edu Confidentiality Notice: This document is protected by EDUCATIONAL LAW 6527 PUBLIC HEALTH LAW 2085, J, K, L, M.

Cortical thickness map for a pediatric case
by Sneha Pandya 24 Aug '17

24 Aug '17

Dear team, I have completed cross-sectional pipeline on my pediatric case with a baseline and 4 follow up time points between 4-7 years of age. However, I was not able to run longitudinal pipeline on it as the base template creation failed with some topological errors. I assume this failure is due to large eTIV changes within 4-7 years of age. I wanted to compare cortical thickness map of follow-up time points to its baseline using qdec. However, I was not able to as running qdec with single subject failed with 0 dof error. Can you'll please suggest how can I generate cortical thickness map between follow-up and baseline scans for this subject if qdec is not an option. Thanks, Sneha

Discrepancy between estimated area of a label
by Sheraz Khan, PhD 24 Aug '17

24 Aug '17

Hi, I am trying to estimate, area of a label on the white surface. I calculated area by summing areas of all the triangles in the label (half of the magnitude of the cross product of the vectors spanning sides of a triangle), when I compared my result with "mris_anatomical_stats" there is a discrepancy, my code underestimate the area. I am wondering is there any correction factor, I am missing ? The gist of the code is at https://gist.github.com/SherazKhan/9cbb5520d4efb39bc90f5b175a60a3c5 Thanks __sk__

sub cortical analysis
by John Anderson 24 Aug '17

24 Aug '17

Hi Dr Greve, I am using pet surfer to analyze suv images. I followed all the steps in wiki, I used the option mgx then I fed the images mgx.{ctxgm,subctxgm,gm} into surface based analysis for left and right hemispheres. I want to inquire about the sub cortical analysis. 1. I assume the analysis for sub cortical gray matter (i.e. using the images subctxgm) is volumetric. Correct? 2. Are the following steps correct for sub cortical gray matter analysis mri_vol2vol --mov subctxgm.nii.gz --reg reg.dat --tal --talres 2 --talxfm talairach.xfm --nearest --no-save-reg --o subctxgm.tal2mm.nii.gz mri_mask subctxgm.tal2mm.nii.gz $FREESURFER_HOME/subjects/fsaverage/mri.2mm/subcort.mask.mgz subctxgm.tal2mm_subc.nii.gz & Concatenate all subjects together using mri_concat smooth using mri_fwhm (what is the recommended smoothing for suv)? Then Group analysis: mri_glmfit --y all.suvr.tal2mm.subc.sm10.nii --fsgd fsgd.dat --C contrast.mtx --glmdir dir mri_glmfit-sim --glmdir dir --grf 1.3 pos --cwpvalthresh 0.0166 for "mri_glmfit-sim" in subcortical structure is the flag grf correct or cache? Thanks in advance! John
