RHEL 7 and tkmedit {Disarmed}
by Tracy Riggins 29 Nov '20

29 Nov '20

External Email - Use Caution Dear Freesurfer Gurus We just upgraded our server to RHEL 7. However, we want to do some white/pial edits on some brains using Freesurfer 5.1.0. We know this is an old version, but we are combining some new data with a lot of old data that had been processed before in 5.1.0 and ... we want to use the old version. However, when using tkmedit the error below was received. Can you help? Thanks in advance, Tracy =================================== ERROR: A segfault has occurred. This is not your fault, : but is most likely an unrecoverable error and has : made the program unstable. : : Please send the contents of the file .xdebug_tkmedit : that should be in this directory to freesurfer(a)nmr.mgh.harvard.edu : : Now exiting... *Contents of the the file .xdebug_tkmedit here:* tkmedit started: Wed Nov 18 10:50:06 2020 /cell_root/software/freesurfer/5.1.0/sys/tktools/tkmedit.bin SLP003_practice_KK brainmask.mgz -aux wm.mgz -surfs $Id: tkmedit.c,v 1.343 2011/03/01 01:41:22 nicks Exp $ $Name: stable5 $ Set user home dir to /export/data/seahorse_ncdl/SLP/data/white_pial_practice Set subject home dir to /export/data/seahorse_ncdl/SLP/data/white_pial_practice//SLP003_practice_KK Segfault Importing volume with MRIread xDebug stack (length: 5) 04: Volm_ImportData( this=0x27f57890, isSource=/export/data/seahorse_ncdl/SLP/data/white_pial_practice//SLP003_practice_KK/mri/brainmask.mgz ) 04: Importing volume with MRIread 03: LoadVolume( iType=0, isName=brainmask.mgz, ibConform = 0 ) 03: Reading data into volume 02: ParseCmdLineArgs( argc=6, argv=/cell_root/software/freesurfer/5.1.0/sys/tktools/tkmedit.bin ) 02: Loading volume brainmask.mgz 01: main() 01: Parsing command line arguments 00: 00: ] -- Tracy Riggins, Ph.D. Associate Professor Secretary, Cognitive Development Society Department of Psychology 4094 Campus Drive Biology/Psychology Building Room 2147J University of Maryland College Park, MD 20742 (301) 405-5905 http://secure-web.cisco.com/1BXBdC5OSLi3H7WL6XT9HhLP6upr-VMDdJcVP0_Zi60l0rJ… https://secure-web.cisco.com/1707dQrUylXr-ioQLaAeJuIXFc8V8l-3l8Gsf5fqQmfGql… riggins(a)umd.edu Pronouns: she/her/hers

calculating hemisphere total grey matter volume
by Vicente Ferrer 29 Nov '20

29 Nov '20

External Email - Use Caution Hello Freesurfer, Once I had run reconall, I tried to calculating left hemisphere total grey matter volume and right hemisphere total grey matter volume by doing the sum of: TGM_left=lhcortexvol + Left-Cerebellum-Cortex + (Left-Thalamus-Proper + Left-Caudate + Left-Putamen + Left-Pallidum + Left-Hippocampus +Left-Amygdala +Left-Accumbens-area +Left-VentralDC) using the volumes values of the aseg.stats file. I did it like this because of the definitions of TGM in this webpage: https://secure-web.cisco.com/18pk-Ax0hgeQLjPCil_KNGcr0ZuCL3RBLq8NqkvLiWHU5V… However I did a saninty check and compared the TGM_estimated=TGM_left + TGM_right. with the measurement in the aseg file: Measure TotalGray, TotalGrayVol, Total gray matter volume. They are similar but not the same. Which makes me wonder if this is not the proper ay of calculating it. Therefore: which is the best way of calculating left hemisphere total grey matter volume and right hemisphere total grey matter volume in a separated manner? Thanks in advance, Vicente Ferrer Predoctoral Researcher BCBL http://secure-web.cisco.com/1Y80FAmAIDLnW-nPDCMBRDUQbmyy9_KQJaimWnm60B6mbmp… Legal disclaimer/Aviso legal/Lege-oharra: http://secure-web.cisco.com/1HBxObiSRumyzSCM72mU7-knka-loKiKejfXjeLERlyDL2E…

qdec replacement
by Pagliaccio, David (NYSPI) 29 Nov '20

29 Nov '20

External Email - Use Caution Hello I was just wondering if there were any updates on a FSv7 replacement for QDEC for vertex-wise cortical thickness analyses? Or if there were any recommendations for analyses in other programs? Thanks!

smoothing on ?h.w-g.pct.mgh files
by Enrico Collantoni 29 Nov '20

29 Nov '20

External Email - Use Caution Dear Freesurfer experts, I computed the gray to white matter signal intensity ratio using the pctsurfcon command and extracted the ?h.w-g.pct.mgh files. How can I conduct a smoothing procedure on these surface files? Thanks for your help, -- Enrico Collantoni MD, Ph.D., Psychiatrist University of Padua Neuroscience Department

use different parameters of MRI DICOM
by 王颖喆 29 Nov '20

29 Nov '20

External Email - Use Caution Hello Freesurfer Developers, I'm attempting to analyze data using freesurfer. The dataset we used includes two different series of MRI DICOM: The first series (n=562) was collected using the following paremeters: t1_fl3d (Voxel Size = 0.9×0.9×1.5mm, FOV = 220 mm, TR = 21ms, TE = 7.65ms, Flip Angle = 30⁰); The second series (n=300) : MPRAGE(Voxel Size = 1×1×1mm, FOV = 256mm, TR = 2300ms, TE = 2.98ms, Flip Angle = 9⁰). All brain MRIs were performed on the same 3.0T Siemens scanner. I'd like to know if it is accpetable to include both of these imagings in one analysis? Is there any pre-processing step need to be done? Thank you! Yingzhe Wang

External Email - Use Caution Hi FreeSurfer experts Recently I started working on the longitudinal data. I followed the pipeline described in the below link. Also, I attached my longitudinal table along with freesurfer data. https://secure-web.cisco.com/1DF2osKRIq2P6tkekGvGP9JanombamauC9_0TALJPJG645… I got the error while executing the following commands: CM.C = [zeros(3,5) [1 0 0 0 0 0 0;-1 0 0 1 0 0 0;0 0 0 -1 0 0 1] zeros(3,5)]; F_lhstats = lme_mass_F(lhstats,CM); And the Matlab threw an error shown below >> CM.C = [zeros(3,5) [1 0 0 0 0 0 0;-1 0 0 1 0 0 0;0 0 0 -1 0 0 1] > zeros(3,5)]; > >> F_lhstats = lme_mass_F(lhstats,CM); > Error using lme_mass_F (line 50) > The number of colums in the contrast matrix CM(1).C is different from the > corresponding number of fixed effects in stats(1).Bhat Any help would be appreciated!
