Error in hippocampal subfield segmentation

Hippocampal subfield segmentation problem
by Artyom Zinchenko 22 May '17

22 May '17

Dear experts, I am running running hippocampal subfield segmentation using the most recent version of the FSv6.0 on LinuxMint 17.3 Rosa. For some (~ 25%, but not all) participants I did not get the subfields. I have later realized that although segmentation finished with out errors, I got the following message in the end: Error using kvlGEMSMatlab std: :bad_alloc Error in kvlRasterizeAtlasMesh (line 11) Error in segmentSubjectT1_autoEstimateAlveusML (line 628). I have read that I need to check whether the T1resampled.mgz actually exists in the temporary directory of the subject. I have checked and this file is indeed there: SBJ/tmp/hippoSF_T1_v10_right/T1resampled.mgz. Please, let me know if this is a known problem and if there is anything I can do to correct it? Thank you very much in advance, Artyom

wmsubseg and hippocampal subfield in gtmseg
by Chakmeedaj Sethanandha 22 May '17

22 May '17

Dear Freesurfer Experts, We have experiment on functional change based on PET in white matter and found that freesurfer's gtmpvc is very much helpful. We would like to ask if we can get gtmseg to subsegment wm in to gyral based parcellation instead of lobar wm? We know that we can create our own segmentation based on wmparc.mgz but it would be better to have a more automate way. On this matter, we also would like to add hippocampal subfield as segmented by "-hippocampal-subfields-T1" in recon-all for gtmseg results. Will this be allowed? Best, Jak

-usegpu vs -parallel in recon-all
by Octavian Lie 20 May '17

20 May '17

Dear All, With FS6, -parallel -openmp x can really speed things up. I inherited code from prior versions using -usegpu flag for GPU/CUDA (not supported more recently). Is the latter redundant or affecting in any way the -parallel -openmp x performance, should we take it out, please advise. Thank you, Octavian

Cuda 8, Centos 7, FreeSurfer 6
by neuroimage analyst 20 May '17

20 May '17

Hello. We recently installed Centos 7 with cuda 8 and tried to build the FreeSurfer 6.0 using the wiki instructions but were unsuccessful to do so. Has anyone successfully built FreeSurfer 6 on Cuda 8 (Centos 7) and willing to share the binaries with us or share their steps with us? We will greatly appreciate that. Thanks Regards V

ERROR: nu_correct
by Das S. 20 May '17

20 May '17

Dear Freesurfer Developers, I was trying to use the recon-all -autorecon1 -subjid bert and got an error. When I checked I found the error was coming while executing the below command: nu_correct -clobber ./tmp.mri_nu_correct.mni.7555/nu0.mnc ./tmp.mri_nu_correct.mni.7555/nu1.mnc -tmpdir ./tmp.mri_nu_correct.mni.7555/0/ -iterations 1000 -distance 50 When I executed the command separately I got below error message: Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at /usr/local/freesurfer/mni/bin/nu_estimate_np_and_em line 165. nu_correct: crashed while running nu_estimate_np_and_em (termination status=65280) ERROR: nu_correct Can you please suggest why the error is coming and how to remove it. Many thanks Sarbani

Dear Bruce, Thank you for answering my question. However, I'm still in a bit confused... Therefore, I have one more question: Would it then be best to choose a particular WM intensity value to rely upon for adding control points or to rely upon sight? Thank you very much!

Corrupted file (Matlab runtime 2012b Linux) on server?
by Marco Bucci 19 May '17

19 May '17

Hi all, I tried on a Linux server with Debian (also as sudo) curl "http://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime?action=AttachFile&do…" -o "runtime2012b.tar.gz" The transfer stops at about two minutes from the end. I tried to download the file manually from the website on a Mac, the transfer stops at 195 MB and does not finish, then timeout. Is it possible you have a corrupted file on the server at the moment? Can you help me? Best regards, Marco P.S. Also my colleague tried separately to download and the problem was still present. -- **************************************************** Marco Bucci, PhD in Clinical Physiology and Nuclear Medicine Turku PET Centre Turku University Central Hospital (TUCH) PL 52, Kiinanmyllynkatu 4-8, 20521 Turku, Finland tel. +358 2 3132798 fax. +358 2 2318191 mobile: +358 40 6873976 UTU e-mail: marbuc(a)utu.fi ****************************************************

Grey matter misclassified as white matter
by Maryam Kouchakidivkolaei 18 May '17

18 May '17

Dear experts, I am using freesurfer V5.3. I am trying to fix some error in freesurfer outputs. The issue is that grey matter misclassified as white matter in temporal lobe (lh). I tried to edit Wm.mgz and re-run with -autorecon2-wm, but it did not work. Looking at the brainmask.mgz, white matter boundary includes area with intensity normalization less than 60-50. Any suggestion? I appreciate any help, Maryam
